Description

8 mV/µm or 2.5 µA/µm (2 mm range), −40 to 180 °C, Ø5 mm tip, standard-mount.

The TQ401 proximity sensor is a high-quality, high-reliability sensor for use with an EA401 extension cable and IQS900 signal conditioner, which provides either a voltage output or a current output.

The TQ401 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).
