Contrinex through-beam ring sensors are available in three different sizes, and consequently suitable for a large range of applications. They feature a very robust, compact and universally mountable housing. They are used mainly in assembly technology for material-flow monitoring of small parts, such as screws, springs, plastic parts, etc, in transparent feeder tubes.

Thru-Beam Ring Sensor

The devices consist of an amplifier and a connectable sensing head, which contains several throughbeam sensors. Consequently, small metallic and non-metallic parts from Ø 1 mm can be detected.

The sensing heads can be combined with dynamically or statically operating amplifiers. The advantage of the dynamic operating principle is that it does not require re-adjusting when the feeder tube is soiled or scratched. On the other hand, static amplifiers also detect non-moving parts, i.e. can for instance be used for monitoring jams.

A Wide-Gap Model is available for loose-fitting doors and windows. The 1055 series of magnetic contacts is designed for tight-fitting installations. The 1/4-inch diameter makes the contacts perfect for applications such as casements or awning-style windows and security screens. The contacts can be either recessed or surface mounted in window frame channels, and are difficult to detect in recessed door applications.

Weidmuller Isolators

The PRO RTD Isolating Transformers come with either a screw or tension-clamp wire connection. The 24 V DC supply voltage can be bridged using pluggable ZQV 2.5N jumpers on the module side.
