High Voltage Reed Relays

Pickering Reed Relays for high voltage applications can stand-off from 1kV to 15kV and switching 500V to 12.5kV at up to 50W. Available with PCB pins, chassis or PCB mounting & flying leads for HV connections.

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.

Pickering Series 60 & 65

High Voltage Dry Reed Relays
For up to 15 kV

• SoftCenter ® construction
• Up to 15 kV stand-off
• 12.5 kV switching
• Small size
• Easy mounting
• Long life
• Fully encapsulated

Series 60 Chassis mounting with solder connections on the top face

Series 65 Printed circuit mounting

The Series 60 and 65 ranges of high voltage reed relays have been manufactured for many years and remain popular due to their small size and ease of use.

They are available for up to 15kV stand-off, 12.5kV switching at 50 Watts maximum. Tungsten plated contacts ensure a long and reliable life.

Pickering Series 62 & 63

High Voltage Dry Reed Relays
For up to 15 kV

• SoftCenter ® construction
• Up to 15 kV stand-off
• 12.5 kV switching
• Small size
• Easy mounting
• Long life
• Fully encapsulated

Series 62 Chassis mounting with push-on connections on the top face

Series 63 Printed circuit mounting with push-on high voltage connections on the top face

The Series 62 and 63 ranges of high voltage reed relays feature push-on terminals and are supplied complete with the appropriate connectors and insulating boots.

They are available for up to 15kV stand-off, 12.5kV switching at 50 Watts maximum. Tungsten plated contacts ensure a long and reliable life.

Both Form A (energize to make) and Form B (energize to break) configurations are available and it is usually possible to achieve a Form C (change-over) function by using a Form A and a Form B type together.

Pickering Series 67 & 68

High Voltage Dry Reed Relays
For up to 10kV

• Option of flying leads for high voltage connections
• Up to 10kV stand-off, 7.5kV switching
• SoftCenter ® construction
• Small size
• Easy mounting with pins on Single-in-Line format
• Robust tungsten plated contacts
• Fully encapsulated
• Internal mu-metal magnetic screen
• Option of internal diode across the coil connections

Series 67 PCB mounting with switch and coil connections in a Single-in-Line format.

Series 68 PCB connections on the underside for coil connections. Flying leads from the top face for high voltage connections.

The Series 67 and 68 are constructed using former-less coils. The absence of a coil supporting bobbin allows a device smaller than the industry norm. The unusual package design gives some interesting possibilities for high density packing.

The option of flying leads for the high voltage connections makes it possible to keep this away from lower voltage circuitry on the pcb.

Form A (energize to make) contacts are available with the option of 5, 12 and 24 volt operating coils.

Pickering Series 104

High Voltage SIL Reed Relays
For up to 3 kilovolts

• SoftCenter ® construction
• Highest quality instrumentation grade switches
• Small size
• Internal mu-metal magnetic screen
• One or two switches in a single package
• Form A (energize to make) or Form B (energize to break) configurations
• Dry and mercury wetted switches available
• 5, 12 and 24 Volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance

The Series 104 is a range of Single-In-Line reed relays intended for voltages that are beyond the capabilities of conventional SIL reed relays.

They are ideal for such applications as transformer or cable testing or any other automatic test equipment where high voltages are involved.

Pickering Series 119

High Voltage Micro-SIL Reed Relays
For up to 3 kilovolts

• SoftCenter ® construction
• Smallest high voltage relays currently available
• Highest quality Instrumentation Grade vacuum reed switches
• Internal mu-metal magnetic screen
• One or two switches in a single package
• 1 Form A (energize to make) up to 3kV
• 2 Form A (energize to make) up to 1kV
• 1 Form B (energize to break) up to 1kV or 2kV
• 3, 5 and 12 Volt coils are standard, with or without
internal diode
• 100% tested for dynamic contact resistance

The Series 119 is a range of Micro-SIL Single-In-Line reed relays intended for voltages that are beyond the capabilities of conventional SIL reed relays. The 1 Form A, 1kV version is pin and package compatible with the established and popular Series 109P.

They are an ideal choice for Cable testers, Mixed signal ATE or any other applications where high voltage capability is required and where space is at a premium.

Pickering Series 131

SoftCentre-Formerless-Coil

High Voltage Mini-SIL / SIP Reed Relays
Minimum 1500V Stand-off

• Choice of 3, 5 or 12 Volt coils, with optional internal diode
• 1 Form A (energize to make) SPST N.O configuration
• Smallest high voltage relay currently available
• Switching up to 0.7 Amps, 10 Watts
• Ideal for cable testers, mixed signal/semiconductor
testers, backplane testers, high voltage instrumentation,
in-circuit test equipment or other applications where
high voltage capability is required.
• Internal mu-metal magnetic screen allows side by side
stacking without magnetic interaction
• 100% tested for dynamic contact resistance
• Unique SoftCenter ® construction (see diagram)
• Highest quality vacuumed, sputtered ruthenium reed
switches

The Pickering Series 131 is a new range of very small Single-In-Line reed relays intended for voltages very much higher than standard small SIL relays. The vacuumed, sputtered ruthenium reed switches have a superb low level performance also, which makes them an ideal choice where a wide range of signals are involved.

The range is based on the long established Series 113 style of plastic package with an internal mu-metal magnetic screen which allows high packing density and are made using Pickering's SoftCentre® construction.
