HIGH VOLTAGE RELAYS
Please see Pickering’s full range of high-performance reed relays for high voltage applications below. These small relays can stand off from 1.5kV to 15kV and switch 500V to 12.5kV at up to 200W. 1 Form A, 2 Form A, 1 Form B and 1 Form C configurations available. Available with PCB pins, chassis, PCB mounting, & flying leads for HV connections.
High voltage isolation relays for many applications include mixed-signal semiconductor testers, high-end cable testers, backplane testers, medical electronics, electric vehicles, solar energy, excellent physics, in-circuit test equipment, and high voltage instrumentation.
Series 131 Mini SIL up to 1.5kV
The smallest high voltage relays available. 1 Form A. Up to 1500 V stand-off, 1000 V switching. 3, 5, or 12 V coils. Suitable for mixed signal semiconductor testers.
These SPST N.O. relays switch up to 0.7 Amp, 10 Watts and feature the highest quality, vacuumed, sputtered ruthenium reed switches. An internal mu-metal magnetic screen allows side by side stacking without magnetic interaction.
Series 119 Mini SIL up to 3kV
Very small isolation reed relays in Form A and Form B configurations. Up to 3000 V stand-off, 1000 V switching. 3, 5 or 12 V coils. Suitable for cable testers.
The Series 119 is a range of Micro-SIL reed relays intended for voltages that are beyond the capabilities of conventional single-in-line reed relays. Insulation resistance >1012Ω. The 1 Form A, 1kV version is pin & package compatible with the industry standard Series 109P.
Series 104 Mini SIL up to 5kV
Small high voltage reed relays in Form A and Form B. Up to 5000 V stand-off, 1500 V switching. 5, 12 or 24 V coils.
If your application is in a high temperature environment, the 104HT can withstand temperatures up to 125°C (& up to 150°C as a standard build option). Suitable for transformer testing.
Stacking on a 0.25-inch pitch. Dry and mercury wetted switches available. A good choice for automatic test equipment where high voltages are involved. Where mains voltages are switched, for example to control and isolate S.C.R. or triac gates, they are an ideal choice.
There is also an option for an electrostatic shield between the switch and the coil to help minimize noise between the coil drive and high voltage circuits.
Series 100HV SIL for up to 3kV
HV + high coil resistance reed relays in Form A and Form B. 3000 V stand-off, 1000 V switching. 5, 12 or 24 V coils. Up to 6800 Ohms coil resistance.
The relays are suitable for mixed signal applications as the lower coil power reduces the Thermal EMF voltages generated across the switch. The 3 kV version has an increased clearance between the switch and coil pins to accommodate the higher voltage.
Series 67 & 68 SIL up to 10kV
Option of PCB & flying lead connections in Form A and Form C Changeover. Up to 10 kV, 7.5 kV switching. High power 200 W switch available. 5, 12 or 24 V coils.
The relays feature tungsten plated contacts to ensure a long and reliable life. Series 68 PCB contains connections on the underside for coil connections. Flying leads from the top face makes it possible to keep the higher voltage away from lower voltage circuitry on the PCB. There is also an option for an electrostatic shield between the switch and the coil to help minimise noise between the coil drive and high voltage circuits.
Series 62 & 63 up to 15kV
Option of chassis or PCB mounting with push-on HV connections. Form A & Form B. Up to 15 kV, 12.5 kV switching at 50 W max. 5, 12 & 24 V coils.
The Series 62 & 63 ranges of high voltage relays feature push-on terminals & are supplied complete with the appropriate connectors & insulating boots. Special versions with an electrostatic screen and/or earth connection to the magnetic screen are available on request.
Series 219 up to 5kV
All contact configurations are offered with three coil voltages, 3V, 5V, or 12V. Switch stand-off is up to 1.5kV in the 2 Form A package, up to 2kV in 1 Form B, and up to 3kV in the 1 Form A package, while switch-coil isolation is up to 5kV stand-off in 1 Form A and 1 Form B types.
Switching is up to 0.7A and 10W, while the operating temperature range spans from -40°C to +105°C.
Series 60 & 65 up to 15kV
Option of chassis or PCB mounting with push-on HV connections. Form A & Form B. Up to 15 kV, 12.5 kV switching at 50 W max. 5, 12 & 24 V coils.
1 Form A version switch up to 12.5 kV, 1 Form B versions switch up to 7.5 kV. Series 60 feature chassis mounting with solder connections on the top face. Series 65 are for printed circuit mounting. Tungsten plated contacts ensure a long and reliable life.
Series 144 – up to 3kV
2 A switching at up to 60 W, or 1 A switching up to 80 W, with a continuous carry current of up to 3 Amps. High-voltage capability, with a switching voltage of 1000VDC up to 10W and up to 3kV standoff. 1 or 2 Form A (energize to make) or 1 Form B (energize to break) configurations. 5 , 12 or 24 V coils.
