JEMTECH has released the VSX electronic safety switches. They are able to detect a coded tag at distances of up to 20mm from the sensing head.
The RFID-coded safety switches include the vibration tolerance that comes from the long sensing distance with no mechanical parts. The lack of tongues and other mechanical interlocks allows for sealed operation and suitability for use in hygienic and hose-down environments.
The VSX-TB switch version interfaces with JEMTECH safety relays and Vigilante control units. When interfacing with the Vigilante controllers the devices provide CAT-3 protection using a single pair switch and controller inputs.
They can also be series connected which simplifies wiring and increases the number of switches that may be included in a system.
The basic unit is a 33mm barrel design. Various brackets and mountings are available for the basic unit. The unit uses a quick-connect plug and is rated at IP66 when installed.
