JEMTECH has released the VSX fully-sealed safety switches. They can detect a coded tag at distances of up to 30mm from the sensing head.
Advantages of 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 fully-sealed operation and suitability for use in hygienic and hose-down environments.
The VSX-TA switch version interfaces with Jemtech safety blocks including the SO safety relays and Vigilante control units. When interfacing with the Vigilante controllers as many as eight switches may be wired in series using a single pair of controller inputs. This simplifies wiring and significantly 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 IP68 when installed.
