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.

Choose LED drivers by current, string voltage, dimming and thermal limits. Understand constant-current operation and the checks needed for your load.
