Reed relay company Pickering Electronics has increased the stand-off voltage values for its prevalent small-size Series 104 high voltage reed relays for up to 4kV. This is a 1,000VDC stand-off voltage improvement from the previous Series 104 reed relay product offering. The new Series 104 has reed relays which are suitable for applications that involve high voltages like transformers, cable testing or other automatic test equipment.

Commented Kevin Mallett, Technical Specialist at Pickering Electronics: “The higher stand-off voltage improves the performance of the relay and allows for an increase in the equipment specification.” “It also means an increased high voltage protection margin for extra safety and security,” he added.

There are four types of dry switches available that are equipped for stacking on 0.25 inches pitch and standing-off 1.5, 2, 3 or 4kV d.c. The 3kV and 4kV versions have a higher clearance between the switch and coil pins to integrate the higher voltage. Mercury wetted devices are usable for applications where bounce free switching is required. It is rated at 1,500 volts d.c. minimum stand-off, 500 volts d.c. switching at up to 50 watts.
