TQ902-011 111-902-000-011 A5-B1-C75-D2-E10000-F2-G9800-H10 Proximity Sensor

Description

The active part of a TQ9xx proximity sensor is a coil of wire that is moulded inside the tip of the device, made of PPS (polyphenylene sulfide), a high-performance, high-temperature engineering thermoplastic. The sensor body is made of stainless steel. The target material must, in all cases, be metallic.

The TQ902 and TQ912 proximity sensors are essentially the same except that the TQ902 is intended for standard-mount and the TQ912 is for reverse-mount applications. Both sensor bodies are available with metric or imperial threads and  have an integral coaxial cable terminated with a self-locking miniature coaxial connector. A TQ9xx sensor’s integral cable and the EA90x extension cables are available in various lengths, which can be combined to obtain a particular total system length (TSL) for an application.

Optional interconnection protectors (IP172), junction boxes (JB118) and other housings are available for the mechanical and environmental protection of the connection between a TQ9xx sensor’s integral cable and an EA90x extension cable.
