Advancing Technology for RAIL Applications
Leach relays and contactors are designed for critical, fail-safe applications. Their unique design ensures that if, in the unlikely event that one contact welds,then no contact will close to the opposite state.
Dust and iron filings from brakes and tracks can penetrate into a relay's plastic can, this is attracted by the coil's magnetism. Leach's components, which are hermetically sealed in metal cans and then filled with nitrogen gas are not subject to these contaminants and pollutants.
Leach relays can withstand the temperatures of harsh environments and also have the ability to endure high vibration (20G) and shock (200G). Most components are manufactured to the ISO-9000 certification.
