Proximity Sensors are designed to detect and respond to movement outside of the component and within the range of the sensor (0” (0 mm) to 50’ (15.2 m)). The sensor types include capacitive, inductive, infrared, light, and ultrasonic with output types of analog current, voltage, configurable, I2C, NC, NO, NPN, 2-wire, 3-wire, 4-wire, 5-wire, PNP, push-pull, relay, requires amplifier, and SCR.

Understand how a comparator switches at a voltage threshold, why hysteresis prevents chatter, and which output and input specs matter.
