StoneL PQ2SC2R Valve Position Sensor E70

StoneL PQ2SC2R Quartz PQ Valve Position Sensor, E70 is a valve-position transmitter that provides feedback on a valve's opening for integration with process-control systems. The unit uses SPDT contacts and is specified for 0.3 A at 120 VAC, making it suitable for signaling valve status to control circuits. It is designed for harsh environments with a -40°C to 80°C operating range and enclosure ratings of NEMA 4, 4X, and 6, supporting washdown and outdoor installations. The PQ2SC2R has a reported weight of 5.0 lb. The model is listed as discontinued by the manufacturer, so availability may be limited to remaining stock or third-party sources. In typical applications, it serves as the valve-position feedback element in automated valve assemblies, enabling accurate open/closed or proportional position sensing for process control loops.
