The Pickering Series 111 is a range of magnetically screened single-in-line reed relays that stack on 0.15 inches by 0.4 inches pitch. They have an identical footprint to the Series 110 and 112 but the height is reduced to only 0.26 inches (6.6mm).

The switch rating of 10 Watts is adequate for most instrumentation applications. If a higher power rating is required, please look at our Series 110  which has a 20 Watts rating and an identical pin-out. The range also includes the type 111RF, a 50 ohms coaxial device suitable for use up to 1.5 GHz.

These relays require around one third the board area of the more usual 0.2 x 0.8 inch devices and are ideal for high density applications.

Two package styles are available:
The type 111 is encapsulated in a mu-metal can. The coaxial version, type 111RF, is also available in this
package style.
The type 111P is encapsulated in a plastic package and features an internal mu-metal screen. An internal diode is an option in both types.

Magnetic screening is essential to avoid magnetic interaction problems. Interaction is usually measured as a percentage increase in the voltage required to operate a relay when two additional relays, stacked one each side, are themselves operated. An unscreened device mounted on this pitch would have an interaction figure of around 40%. Relays of this size would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 111 have an interaction figure of around 1 percent.

Pickering Series 112


Single-in-Line Reed Relays
For stacking on 0.15 x 0.4 inches pitch giving SUPERB PACKING DENSITY

SoftCenter™ construction
• Highest quality instrumentation grade switches
• Ideal for high density card based systems and Automatic Test Equipment
• Plastic package with internal mu-metal magnetic screen
• They take up the minimum of board area, conserving
board space
• Many benefits compared to industry standard relays. Learn more here >.
• Insulation resistance greater than 10E12 Ohms (1TOhms)
• 5 Volt coils of 500 ohms may be driven directly from TTL logic
• 5, and 12 Volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance

The Pickering Series 112 is a range of magnetically screened single-in-line reed relays that require a board area of only 0.15 inches (3.8mm.) by 0.4 inches (10mm.) while retaining the 10 Watts, 0.5 Amps rating associated with larger relays.

This small footprint is achieved by mounting the reed switch diagonally within the package.

These relays require around one third the board area of the more usual 0.2 x 0.8 inch devices and the height of only 0.43 inches (11mm.) is suitable for high density card based systems such as VME, VXI, Compact PCI, and PXI. The high quality, sputtered ruthenium switch contacts also makes them ideal for Automatic Test
Equipment.

The Series 112 is encapsulated in a plastic package using a very high resistivity resin to achieve an insulation resistance greater than 1012 ohms. The relay has an internal mumetal screen which totally eliminates the risk of magnetic interaction problems. An unscreened device mounted on this pitch would have an interaction figure of around 40 percent. Relays of this size without magnetic screening would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 112 have a typical interaction
figure of 5 percent.

3, 5 and 12 Volt coils are standard, with the option of an internal diode. 5 Volt coils have a resistance of 500 ohms and may be driven directly from TTL logic.

Pickering Series 113

Single-in-Line Reed Relays

SoftCenter™ construction
• Highest quality instrumentation grade switches
• Plastic package with internal mu-metal magnetic screen
• They take up very little area, conserving board space
• High insulation resistance - greater than 10E12 Ohms (1TOhms) for Form A types and greater than 1E10 (10G ohms) for Form C types

• 5 and 12 Volt coils are standard, with or without internal diode
• 1 Form A, 5 volt version has a coil resistance of 500 ohms - drives directly from TTL logic
• 100% tested for dynamic contact resistance

The Pickering Series 113 is a range of magnetically screened single-in-line reed relays that require a board area of only 0.15 inches (3.8mm.) by 0.5 inches (12.7mm.)

The Form A (energize to make) versions retain the 10 Watts, 0.5 Amps rating associated with larger relays. The changeover version has a 2 Watts rating.

These relays require less than half the board area of the more usual 0.2 x 0.8 inch devices and have a height of only 0.26 inches (6.6mm.) for the 1 Form A and 1 Form C types and 0.35 inches (8.9 mm.) for the 2 Form A type.

The Series 113 is encapsulated in a plastic package using a very high resistivity resin to achieve an insulation resistance greater than 1012 ohms for the Form A types. The relay has an internal mu-metal screen which totally eliminates the risk of magnetic interaction problems. An unscreened device mounted on this pitch would have an interaction figure of around 40 percent. Relays of this size without magnetic screening would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 113 have a typical interaction figure of 5 percent.

3, 5 and 12 Volt coils are standard, with the option of an internal diode. 1 Form A, 5 Volt coils have a resistance of 500 ohms and may be driven directly from TTL logic.

 

Pickering Series 114

High Power Dry SIL Reed Relays

SoftCenter™ construction
• Highest quality instrumentation grade switches
• Small size
• Internal mu-metal magnetic screen
• One or two switches in a single package
• Many benefits compared to industry standard relays. Learn more here >.
• Form A (energize to make) or Form B (energize to break) configurations
• 5, 12 and 24 Volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance

The Series 114 is a range of Single-In-Line reed relays intended for power levels that are beyond the capabilities of conventional dry SIL reed relays.

The more usual dry relays are rated at 0.5 amps at 10 Watts. The Series 114 have a rating of 1 amp switching at up to 40 watts and will carry 2 amps. In many cases, this higher rating will allow them to be used as an alternative to mercury wetted reed relays.

Unusually for high power relays, they feature sputtered ruthenium contacts instead of the more common electroplated rhodium or tungsten types. This makes them suitable for low level or “dry” switching also.

They are able to switch a.c. mains voltages so are suitable for interfacing to larger electromechanical relays or contactors. It is important however, to suppress back EMFs from inductive loads. This is achievable by using an RC snubber, varistor or similar voltage limiting device.

1 or 2 Form A (energize to make) or 1 Form B (energize to break) configurations are available.

The range features an internal mu-metal screen to minimize problems that would otherwise be experienced due to magnetic interaction when they are closely stacked.

Form A versions may be stacked side-by-side.

Due to the fact that the Form B types feature an internal biasing magnet, a gap of 0.4 inches minimum should be left between adjacent relays.

 

 

 

Pickering Series 115

Single-in-Line Reed Relays
10 or 15 Watts switching - Very high packing density Stacks on 0.15 x 0.27 inches pitch

SoftCenter™ construction
• Highest quality instrumentation grade switches
• Plastic package with internal mu-metal magnetic screen
• They take up the minimum of board area, conserving board space
• Insulation resistance greater than 1E12 Ohms
Many benefits compared to industry standard relays. Learn more here >.
100% tested for dynamic contact resistance for guaranteed performance
5 or 12 Volt coils with optional internal diode

The Pickering Series 115 is a range of Single-in-Line relays intended for very high density applications such as A.T.E. switching matrices or multiplexers.

They are pin compatible with the Pickering Series 116 and 117 but have a slightly higher profile.

The reed switch/coil assemblies used in this series are the same as used in the long established and well proven, Series 109 and 109P.

Two switch types are available. Both types have sputtered ruthenium contacts for long life and high reliability.

Switch type number 1 is better suited for general purpose applications. It has a layer of copper beneath the ruthenium to help dissipate the heat from the contact area. This gives an improved current inrush handling ability.

Switch type number 2 should be chosen for low level or 'cold' switching applications.

Single switch versions require a board area of only 0.15 inches x 0.27 inches. This is one quarter of the board area of the industry standard 0.2 x 0.8 inches Single-in-Line package. The very small size of these relays often makes it possible to increase the functionality of existing designs without increasing the size of printed circuit boards.

The relays feature an internal mu-metal magnetic screen. Mu-metal has the advantage of a high permeability and low magnetic remanence and eliminates problems that would otherwise occur due to magnetic interaction. Relays of this size without magnetic screening would be totally unsuitable for applications
where dense packing is required.

3 volt, 5 volt or 12 volt coils are available. An internal Back E.M.F suppression diode is available as an option.

• Plastic package with internal mu-metal magnetic screen
• They take up the minimum of board area, conserving board space
• Insulation resistance greater than 10E12 ohms
• Many benefits compared to industry standard relays. Learn more here >.

The Pickering Series 116 is a range of Single-in-Line relays intended for very high density applications such as A.T.E. switching matrices or multiplexers.

They have a switch rating of 10 Watts, 0.5 Amps and are pin compatible with the Pickering Series 117 which have a lower power rating of 3 Watts and a lower profile height of 0.38 inches (9.65 mm).

Switches have sputtered ruthenium contacts making them ideal for low level or “cold” switching applications.

1 or 2 pole, Form A (energize to make) versions are available.

The single pole version uses the same switch and coil assembly as the Pickering Series 112.

Single switch versions require a board area of only 0.15 inches x 0.27 inches. This is one quarter of the board area of the industry standard 0.2 x 0.8 inches Single-in-Line package. The very small size of these relays often makes it possible to increase the functionality of existing designs without increasing the size of printed
circuit boards.

The relays feature an internal mu-metal magnetic screen. Mu-metal has the advantage of a high permeability and low magnetic remanence and eliminates problems that would otherwise occur due to magnetic interaction. Interaction is usually measured as a percentage increase in the voltage required to operate a relay when additional relays, st
