E50 Mechanical Limit Switch
E50 Heavy Duty Plug-in Limit Switch
The E50 Modular Plug-in Limit switch has components from the electrical sector are versatile switches that are industry standard in reliability in environments that require exceptional chemical resistance. Viton gaskets, seals and boots and a zinc die-cast enclosure ensure resistance to coolants, cleansing agents, and hydraulic fluids. Modular, plug-in components provide flexibility, reducing inventory and downtime. Mounting dimensions accommodate both U.S. and DIN standards for easy retrofit installations., Super bright 24-120Vac/dc LED indication light versions to simplify setup and troubleshooting operations.
