Magnetically Screened up to 20W Reed Relay

All Pickering reed relays feature the highest quality instrumentation grade reed switches making them suitable for the most demanding applications. Internal mu-metal magnetic screens (optional on Series 103) allow very high packing density. Diodes are optional.

Pickering Series 107

Mini-SIL / SIP Reed Relays
For stacking on 0.2 inches pitch

SoftCenter construction
• Highest quality instrumentation grade reed switches
• Encapsulated in patented mu-metal can
• Insulation resistance greater than 10E12 Ohms (1TOhms) for Form A devices
• Dry and mercury wetted reed switches available
• Many benefits compared to industry standard relays. Learn more here >.
• Wide range of switch configurations - 1 Form A, 1 Form B, 2 Form A, 1 Form C, and 2 Form C
• For R.F. or high speed digital applications, 50 ohms coaxial reed relays are available in the same package style, see Series 102M reed relays
• 5, 12 and 24 Volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance

The Series 107 Mini-SIL range of reed relays are intended for stacking on 0.2 inches (5.08mm) pitch.

Single or double pole Form C (changeover) reed relays switching 0.25 Amps at 3 Watts

Their small size, superb contact resistance stability and ultra high insulation resistance, make these relays an ideal choice for high quality instrumentation.

The mu-metal case ensures virtually total magnetic screening, see explanation below.

Both dry and mercury wetted switches are available in a wide range of configurations.

If even greater packing density is required, smaller devices are available in other Pickering SIL ranges (except for two pole changeover types).

Magnetic Interaction - An explanation
Magnetic interaction between relays is normally expressed as a percentage increase in the voltage required to operate the relay, due to the extraneous fields from adjacent relay coils.

An unscreened SIL relay of this size would have an interaction figure of around 30 percent, i.e. the voltage required to operate it will increase by this amount when relays alongside are operated also. It may prove impossible to use such a relay at its nominal coil voltage in high density applications.
