Pickering’s Series 100 and 101 have low levels of thermal EMF for improved resolution when used to switch thermocouples.
We understand that choosing the right Reed Relay for your application can be daunting. If you are unsure which Reed Relay will best suit your product, please do not hesitate to contact us. Our technical experts will be happy to assist you in any queries you may have regarding Reed Relays.
Low Thermal EMF Relays
Direct drive from CMOS
• SoftCenter™ construction
• Highest quality instrumentation grade switches
• Thermal EMF about 1 microvolt or less
• Low power consumption, ideal for portable equipment
• Encapsulated in a plastic package with internalmu-metal magnetic screen
• 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
• Insulation resistance greater than 10E12 Ohms (1TOhms) for dry Form A devices
• 5, 12 and 24 volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance
The Pickering Series 100 is a complete range of Single-in- Line (SIL) reed relays primarily intended for direct drive from 4000B CMOS or similar low current sources. They feature a very low level of thermal EMF.
CMOS Drive High Voltage SIL 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
• Many benefits compared to industry standard relays. Learn more here >.
• 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.
