Migatron's RPS-409A-IS ultrasonic sensor
The RPS-409A-IS is an intrinsically safe, UL-listed analog ultrasonic sensor. It is a self-contained sensor in a 30 mm PVC barrel housing. It is powered by 16-30 Vdc with reverse polarity protection. It also has a narrow beam angle, designed for tight places. A flat target can tilt up to 10° and be detected. The RPS-409A-IS has a short-circuit-protected analog 0-10 Vdc output. The RPS-409A-IS has built-in temperature compensation, designed to provide accurate readings throughout the entire operating temperature range.
