Standex Electronics introduces a new BH series of high-power reed relays. This relay series can switch up to 1 kVDC while providing a breakdown voltage of 3 kVDC and higher across the open contacts.

The integrated Electrostatic Shield and axial switch leads ensure high insulation resistance of 10 TOhm across the open contacts as well as between the coil and contacts. Also, as a result, very Low Leakage Current in the picoamperes range. The outer Magnetic Shield protects the relays against a mutual interaction and therefore allows an assembly with higher density.

This variable Multi-channel Dry-switch design can be built with up to 4 switches Form A and, thanks to its features such as reliable switching behavior, long lifetime, and low contact resistance (ON-Resistance), it makes an ideal relay for precise testers, automated test equipment or an alternative for mercury relays. Typical applications include automated and semiconductor test equipment, high-insulation/high-accuracy testers, test and measurement, high-voltage industrial, general purpose, and mercury wetted replacement.

Features include 1,000 VDC switching voltage, breakdown voltage 3 kVDC and higher across the open switch, off-state leakage current in picoampere range, multi-channel dry-switch design with up to 4 Form A switches, magnetic shield for high-density assembly, and compliance with RoHS and REACH.
