8 mV/µm or 2.5 µA/µm (2 mm range), 4 mV/µm or 1.25 µA/µm (4 mm range), −40 to 180 °C, Ø8.2 mm tip, standard-mount.

The TQ902 proximity sensor is a high-quality, high-reliability sensor for use with an EA902 extension cable and IQS900 signal conditioner, which provides either a voltage output or a current output.

The TQ902 is a standard-mount sensor that is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).

Note: The TQ902 and the TQ912 have the same specifications and performance characteristics but are intended for applications with different installation (mounting) requirements: the TQ902 is a standard-mount sensor and the TQ912 is a reverse-mount sensor.
