Sealed contactor

27 June 2012 Switches, Relays & Keypads

Gigavac announced an addition to its line of EPIC sealed contactors with the MX56 side-mount model. The single-pole, single-throw, normally-open (SPST-NO) device is rated for continuous duty up to 600 A and capable of switching 600 A at 24 V d.c. or a.c., 100 000 times.

The MX56 was developed for high-reliability applications such as military vehicles, buses, emergency vehicles, mining equipment and power backup systems. Lightweight and compact, it utilises Gigavac’s cut throat coil technology, defined as low coil hold power without the noise issues associated with pulse-width modulation coils.

The contactor can be used in nearly any harsh environment including underwater, as well as at temperatures from –55°C to 90°C (up to 200°C with special coils). The MX56 is not position sensitive. An optional SPST-NO auxiliary contact driven off the main armature gives true indication of the main contact position.

Designed and manufactured in the USA, the MX56 is RoHS compliant and engineered to meet the requirements of the MIL-R-6106 military specification. The side mount option has been a request from several customers and provides an important configuration choice for engineers looking to optimise chassis designs. Since it has the EPIC seal, the MX56 can be mounted virtually anywhere in a system.
