Jemtech has upgraded its range of fully-sealed safety switches. The new VSY types can detect a coded tag at distances of up to 30mm from the sensing head with reduced power consumption and high temperature operation.
Advantages of RFID-coded safety switches include the vibration tolerance that comes from the long sensing distance with no mechanical parts. The lack of interlocking tongues and other mechanical parts allows for fully-sealed operation and suitability for use in hygienic and hose-down environments.
High visibility LED indicators makes it easy to see the status of the switch in any location.The VSY switches are available with sensing heads on the front, side and back. They work with a variety of coded tags that trade size, cost, sensing distance and area. Tags are available which allow 30mm sensing range over an area of 30mm x 60mm. The various of tags ensures that there is a safe and convenient mechanical solution for all types of gates and doors.
These switches interface with JEMTECH safety controllers and relays and provide CAT-3 and CAT-4 protection using a single switch and a pair of controller inputs. The units are fully molded parts rated to IP68. They are available in low-cost cable tail versions or M12 quick release connectors. Additionally the units are 100% production tested for extreme temperature operation to 60C.
