"The MSA Non-contact Coded Switches have been developed as standalone mountable devices to provide a high level of fault detection and functional safety. These non-contact switches can be mounted to guard doors to provide and maintain a high level of functional safety without the need to connect to a safety relay or safety controller. They have their own internal monitoring system and use force guided mechanical contacts which maintain PLe\/Category 4 (ISO13849-1) even when the switches are connected in series. Made from stainless steel 316 with a mirror polished (Ra4) surface finish these safety switches are suitable for CIP and SIP process applications and have IP69K ingress protection. The typical sensing distance of the switch when it is on is 12mm, with wide tolerance to guard misalignment after setting.Standalone device with interlocking control without the need for additional controllers. Feedback circuit check option is included for use when incorporating reset buttons and external contactor feedback checks. Maintains PLe Cat.4 by internally checking the internal mechanical relays at each safety demand. Connect up to 20 switches in series. Ability to connect other switches and E Stops in series. Two diagnostic LED’s to indicate: Guard closed, Actuator present\/removed, Feedback Circuit checked. Output contacts will switch up to 230Vac 3A. The housings are compact and easy to fit on frame sections of less than 40mm. Stainless steel 316 housing (mirror polished finish to Ra4).
