UK-based reed relay maker Pickering Electronics has introduced a high-temperature, high-voltage single-in-line relay that can work at up to 125° C.

The Pickering Series 104HT miniature high-voltage reed relays are offered in the SIL package on a 6.35 mm (0.25 in) pitch and have a stand-off voltage of up to 4 kV. They have built-in mu-metal screening to block magnetic interference. Electrostatic shielding is available as an added option. 

The relays come in a range of configurations, including 1 Form A, 2 Form A and 1 Form B, and can be fitted with coils of either 5, 12 or 24 V, with optional internal diode protection. They can withstand 1.5, 2, 3, or 4 kV DC with four dry switch options. Customized designs for even higher voltage ratings are also offered. For bounce-free switching, mercury-wetted devices are available. These are rated at 1,500 V DC minimum stand-off, 500 V DC switching and up to 50 W.

“By designing these devices with increased magnetic drive and using specialist potting materials to sustain insulation resistance, Pickering offers reed relays that perform at elevated temperatures, and which can be stored at up to 150º C,” said Kevin Mallett, Technical Specialist at Pickering Electronics.
