Lightweight relays

Leach International has developed two small, lightweight relay series - KX and KUL - designed to carry high-current loads up to 300 A.

The KX series can switch 75 and carry 160 A. This series is designed for aircraft, space, rail and high-reliability applications.

Additional features include a single pole, double break configuration, and a temperature range of -55 to 125°C.

For longer life and greater reliability, the relays are hermetically sealed. All relays are designed to MIL-PRF-6106 standards. The series offers various options: model KXL-X9N features a magnetic latch configuration, while KXD-X9N offers an auxiliary switch.

A slightly larger version, the KUL relay series is designed to carry up to 300 A in low voltage space applications. A single pole, double throw auxiliary contact is standard on this relay.

The voltage drop across the terminals is minimised to keep the relay cool while carrying high current.

This relay's light weight of 150 g makes it suitable for space-borne applications. The KUL is hermetically sealed and designed to MIL-PRF-6106 standards.
