Non-contact safety switch for two adjacent doors
With the Mechan Controls HED safety switch you can monitor two adjacent doors with a single switch and a magnetically coded actuator on each door. This saves installation time, cabling, use of parts and costs.
One HED switch costs half the price of two separate switches. The non-contact actuators can approach the switch from most angles with a switching distance of 7 mm. The safety switch complies with PLe, Category 4 and SIL 3.
2 safety contacts
Each HED switch has two NC safety contacts. When opening one of the doors, the safety contacts break and the associated auxiliary contact is closed. Both doors must be closed for the machine to work. LEDs indicate the status of the switch. Three positions are available for the cable connection: left, right or center. In addition, an M12 connector version is available.
