CMOS Drive SIL / SIP 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 101

CMOS Drive SIL/SIP Reed Relays

SoftCenter construction
• Highest quality instrumentation grade switches
• Board space may be saved by eliminating the need for drivers
• Direct drive from 74HC logic
• Encapsulated in a plastic package with internal mu-metal magnetic screen
• Wide range of switch confi gurations - 1 Form A, 1 Form B, 2 Form A, 1 Form C
• Two pole relay requires the same board area as the single pole type
• Dry and mercury wetted switches are available with the same pin configuration and footprint
• 5, 12 and 24 Volt coils are standard, with or without internal diode
• Insulation resistance greater than 10E12 Ohms (1TOhms) for dry Form A devices
• 100% tested for dynamic contact resistance

The Series 101 have very high coil resistances. 5 Volt dry versions may be driven directly from 74HC or 74HCT logic without the need for additional drivers.

74HC logic will drive up to 4mA at 5 Volts, therefore a coil resistance of 1600 ohms is desirable to avoid running the IC at its maximum rating.
