SIL/SIP reed relays handling higher maximum continuous currents

4
(1)

Pickering Electronics has launched the high-power SIL/SIP reed relay 100 HC Series that offers a switching current of 1 A up to 40 W and a maximum continuous current of up to 3 A.

These top quality, instrumentation-grade switches with cathodic sputtered ruthenium contacts are suitable for low level or 'dry' switching applications.

The 100 HC Series high-power SIL/SIP reed relays feature internal mu-metal shielding to minimise the risk of problems caused by magnetic interaction when stacking is dense.

They are available with 5, 12 or 24 V coils with optional internal diode and one or two switches in a single package.

The new SIL/SIP reed relays are suitable for high-power applications and in many cases can be used as an alternative to mercury reed relays.

Comments

Kevin Mallett, Technical Specialist at Pickering Electronics, comments: "The 100HC series offers more than double the coil resistance of other similar products and the maximum continuous current specification of 3A can be increased in pulsed current applications". He added: "The higher coil resistance of the HC Series reed relays also means less heating and therefore a thermo-electromotive force of less than 10 μV."
