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.

In the world of embedded electronics, getting a device to “think” is only half the battle. The other half is getting it to communicate…
