Description

1.33 mV/µm or 0.417 µA/µm (12 mm range), −40 to 180 °C, Ø18 mm tip, standard-mount.

The TQ403 proximity sensor is a high-quality, high-reliability sensor for use with an EA403 extension cable and IQS900 signal conditioner, which provides either a voltage output or a current output.

The TQ403 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).
