Reed Relays for High Power and High Carry Current

Pickering Series 114

High Power Dry SIL / SIP Reed Relays

• One or two switches in a single package
• 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
Customisable options available
• Many benefits compared to industry standard relays. Learn more here >.
• May be used as an alternative to mercury wetted reed relay
• Unique SoftCenter™ construction
• Highest quality instrumentation grade reed switches
• Small size
• Internal mu-metal magnetic screen

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.

Pickering Series 100HC

High Power Dry SIL / SIP Reed Relays

• Up to 3 Amps continuous carry current
• 1 A switching at up to 40 W
• Highest quality instrumentation grade switches
• High coil resistances for low power consumption
• Thermal EMF levels less than 10 μV
• Stacking on 0.40 inches pitch
• Internal mu-metal magnetic screen 
• One or two switches in a single package 
• Form A (energise to make) or Form B (energise to break) configurations
• 5, 12 or 24 V coils with optional internal diode
• Suitable for high power applications and in many cases may be used as an alternative to mercury wetted reed relays

The Pickering Series 100HC offers higher coil resistance than the similar specification Series 114, the greater winding space allowing for the use of switches rated to 3 Amps continuous carry current and even higher levels in pulsed current applications.

Featuring sputtered ruthenium contacts, this also makes them suitable for low level or 'dry' switching applications and the reduced heating effect from the higher coil resistances gives them thermal EMF performance less than 10 μV.

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 67 1 Form A 200W switching

High Power / High Voltage Reed Relays

• 3 A switching at up to 200W
• 8kV stand-off and 6kV switching
• Up to 5 Amps continuous carry current
• Robust Tungsten plated contacts
• Internal mu-metal magnetic screen
• Form A (energise to make)
• 5, 12 or 24 V coils with optional internal diode
• Suitable for high power applications

With a stand-off voltage of up to 8 kV, and capable of 6kV switching at 200W, Series 67 relays are constructed using a lead frame in a Single-in-Line (SIP) format and feature former-less coils which results in a smaller package than is usual for this type of device.

The 67 stands out from our range of relays as it offers higher power and a high current carry. Suitable for high voltage, electro solar and cable testing.
