C&K Switches MPSR Ruggedized Magnetic Proximity Sensor offers a robust 30V 3W rating with a long lifecycle that lasts for more than 4 million actions. This sensor is manufactured for quick, easy, and cheaper installations with zero leakage current. The MPSR ruggedized sensor and magnet are both sealed in a tough aluminum housing combined with stainless steel wire sleeves. This provides environmental protection from grease, oil, water, or volatile chemicals and gases environments. The hermetically sealed contacts ensure inherent insulation of electrical switch contacts from the outside environment resulting in no spark risk. Typical applications include automotive sensors, off-road equipment, IoT, industrial automation, factory automation equipment, remote monitoring, and anti-tamper detections.
