Models from Cherry Switches' MP1013 Series of sensors are Hall-effect position switches, integrated with snap-fit mounting features. They sport comprehensive temperature balance rates, zero mechanical contacts to wear out, and high resistance to dirt, moisture, and more. They also feature 3-wire sinking outputs, 24 AWG PVC-material leads, and either a South Pole-sensitive swtich or a Bipolar latch.
Both the MP101301 and MP101302 models of the series exhibit reverse-battery protective capabilities (-24-V DC).
