The RPS-40-5 is a compact, high frequency sensor. It was introduced to the Migatron family of ultrasonic sensors to better meet the needs of the machine manufacturing industry. This sensor has a wide array of application solutions not found in other proximity sensor manufacturers technologies. The RPS-40-5 has a fixed 0.5-5" sensing range with background suppression (meaning any object with the range is detected, while objects out of the range are ignored). It cannot be affected by changes in target color or material.
