Sick CM Series Capacitive Proximity Sensors Sick CM series capacitive proximity sensors offers high electromagnetic compatibility (EMC), which prevents switching errors. Sensitivity adjustment can be performed quickly and easily using a potentiometer or teach-in button, saving valuable time during commissioning. Sensors installed in inaccessible locations can be equipped with an external, cabled teach-in button. The CM capacitive proximity sensors feature high shock and vibration resistance and minimal sensitivity to dust and moisture. Together with optical adjustment indicators, these features ensure reliable object detection, in turn ensuring reduced machine downtime. Plastic body DC four-wire with PNP normally open and normally closed outputs Extended sensing range with adjustable sensitivity Short circuit and reverse polarity protection Output status LED indication High EMC immunity Output type NO/NC Note ( 786-5958 ) - AC 2-wire
