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.
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
• 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
• Two pole relay requires the same board area as the single pole type
• Many benefits compared to industry standard relays. Learn more here >
• 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; 1600 ohms is the coil resistance of the single pole dry Series
101. They may be stacked on 0.3 inches pitch (7.6mm) and as they have an internal mu-metal magnetic screen, there is no risk of magnetic interaction problems.
Both dry and mercury wetted switches are available in a range of configurations and coil voltages. The switches in the 2 Form A version are vertically stacked so the relay requires the same board area as the 1 Form A type.
A special 1 Form A, 5 Volt version is available with an even higher coil resistance of 3000 ohms. This is particularly suited to applications such as battery powered portable equipment as it requires a coil current of only 1.7 mA. This part, the 101-1-A-5/17 or 17D has the advantage of a lower level of thermal EMF of 3 microvolts or less.
Other special parts are also available that may be operated from 3 Volt logic.
