Description：

The system is based around a TQ402 or TQ412non-contact sensor and an IQS900 signalconditioner. Together, these form a calibratedproximity measurement system in which eachcomponent is interchangeable. The systemoutputs a voltage or a current proportional to thedistance between the transducer tip and thetarget, such as a machine shaft.The active part of the transducer is a coil of wirethat is moulded inside the tip of the device, madeof Torlon® (polyamide-imide). The transducerbody is made of stainless steel. The target materialmust, in all cases, be metallic.The transducer body is available with metric orimperial thread.

The TQ412 version is intended forreverse-mount applications. Both the TQ402 andTQ412 have an integral coaxial cable, terminatedwith a self-locking miniature coaxial connector.Various cable lengths (integral and extension)can be ordered.
