The UK6 series is a line of M18 short body ultrasonic sensors engineered by MD. It is enclosed in a plastic casing for protection from electrical damages.
The sensor features digital outputs. It also provides current, or voltage analog output with programmable switching points, and slope outputs for optimizing resolution. The unit is equipped with an external teach-in, which adjusts the working area to eliminate tampering of sensing distance. It comes in two adjustment modes, and two LEDs.
