TQ422 proximity sensor
4 mV/µm or 1.25 µA/µm (4 mm range), −25 to 140 °C, Ø12.7 mm tip, standard-mount, 100 bar (tip).
The TQ422 proximity sensor is a high-quality, high-reliability sensor for use with an EA402 extension cable and IQS450 signal conditioner, which provides either a voltage output or a current output.
The TQ422 is a standard-mount, high-pressure sensor that is designed and built for long-term use in extreme environments characterised by high temperatures, high pressures and/or hazardous areas (potentially explosive atmospheres).
Note: The TQ422 and the TQ432 have the same specifications and performance characteristics but are intended for applications with different installation (mounting) requirements: the TQ422 is a standard-mount sensor and the TQ432 is a reverse-mount sensor.
