3W, 10W & 20W Standard Size Reed Relays

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 106

Single-In-Line (SIP) Reed Relay
For stacking on 0.2 x 0.8 inches pitch

• SoftCenter construction
• Highest quality instrumentation grade reed switches
• Internal mu-metal screen
• Insulation resistance greater than 10E12 Ohms (1TOhms) for Form A devices
• Many benefits compared to industry standard relays. Learn more here >.
• Dry reed switches available in both 1 Form A / SPST (N.O.) and 1 Form C / SPDT (changeover) configurations
• 5, and 12 Volt coils are standard, with or without internal diode
• 5 Volt coils are 500 ohms and may be driven directly from TTL logic
• 100% tested for dynamic contact resistance

The Series 106 is a range of Single-In-Line reed relays intended for stacking on 0.2 inches pitch. Their small size, superb contact resistance stability and ultra high insulation resistance, make these relays an ideal choice for Automatic Test Equipment & Semiconductor Test.

They have an internal mu-metal screen to eliminate problems that would otherwise be experienced due to magnetic interaction.

While the screening is not quite as efficient as the complete mu-metal can of the Series 107108 or 109, it is more than adequate for most applications.

If even greater packing density is required, smaller devices are available in other Pickering SIL ranges.

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. A Pickering Series 106 reed relay has an interaction figure of
approximately 5 percent.

While the screening is not quite as efficient as the complete mu-metal can of the Series 107, 108 or 109, it is more than adequate for most applications.
