The Swiss sensor manufacturer Contrinex, specialized in long operating distance and miniature devices, now offers a large selection of the world's smallest, fully self-contained inductive and photoelectric proximity switches.
With housing diameters of just 3 mm up to M5, plus cuboid 5 x 5 x 25 mm formats, the sensors have electrical characteristics equivalent to larger types. In addition, they also contain all the usual built-in protection functions, such as short-circuit, voltage-reversal and overload protection, and feature high levels of EMC.
Despite their small dimensions, the inductive models offer operating distances of 0.6 to 1.5 mm. Mechanically robust, with stainless-steel housings and full potting, these devices are highly suitable for rugged applications.
The photoelectric models are available with housing diameters of 4 mm and M5, as diffuse and through-beam executions, and have operating distances from 10 to 250 mm.
These tiny sensors are ideally suited for applications where space is limited. They require no separate amplifiers, and are thus easier to install and considerably cheaper than equivalent fibre-optic solutions.

Compact housing 10 x 14 x 27 mm
Small mass of just 4 grams
Scanning range of 200 mm
Teach-in button and external Teach-in input
Very small blind range
The new miniature ultrasonic sensor generation SONUS with its great performance is in the focus of general interest for good reason.
SONUS, currently the most compact ultrasonic sensors on the market, excel with their tiny housing of just 10 x 14 x 27 mm. A housing for countless applications, particularly for installation in the smallest spaces or for the assembly of several sensors in the tightest places. Ultrasonic technology permits objects to be detected regardless of their color or transparency. Due to their small mass of less than 4 grams, they are optimally suited for installation in all light, quickly-moving handling units. However, the performance data is anything but minute. The scanning range is astounding at 200 mm, for the digitally switching proximity sensors and retro-reflective types and also for the distance measuring versions with analog voltage outputs. All three sensors have a means of electronic Teach-in with a standardized Teach-in sequence. Conveniently by pushing a button on the unit or alternatively via a control input, the desired switching points and scanning ranges of the sensors and the polarity of the 0...10 VDC analog output can be adjusted to any conceivable application. Industrial applications make high demands on the installation, electrical wiring and user-friendliness of sensors. The various sensor variants, such as the cable type, M8x1 plug or cable plug, fulfill these demands. The range is completed by customized package of accessories.

Different object colours and surfaces can heavily effect the detection behaviour of an energetic switch. With purely energetic evaluation, it is, for example, not possible to detect a black object in front of a white background.The white background reflects more light than the object itself.
In order to deal with such applications reliably, the background suppression procedure was developed. In this procedure, both the light reflected by the background and by the object is evaluated.The light is captured by two different receiver elements. With this procedure, it is possible to reliably detect e.g. a dark object on a light color conveyor belt.
There are two different procedures for the physical realisation of background suppression. In general, a distinction is made between a fixed and adjustable background suppression. With a fixed background suppression, the transmitter and receiver elements are rigidly mounted.
The laser units are particularly suitable for the detection of very small objects. With larger objects, a red-light or infrared sensor should be used. Only the background suppression procedure enables the detection of a dark object on a light conveyor belt.

Safety-/ position switches
Monitoring safe positions with LS-Titan
safety position switches From material handling systems to plastic injection moulding; from car washes to doors on trams: the position switches LS-Titan are used wherever there is exact positioning requirement.
The analog position switch with a voltage or current output also enables a range of new applications for the LS-Titan, where mechanical position detection could only provide insufficient information up to now – for example, detecting the position with opened flaps for flue gasses.
World innovation – the electronic position switch LSE-Titan®
electronic position switch The electronic position switch LSE has an operating point that can be set variably. Two fast and bounce-free PNP switch outputs enable high switching frequencies. They are protected against short-circuit and overload and are equipped with an abrupt switching behaviour. This guarantees a defined and reproducible operating point.
The actual operation point is in a range between 0.5 mm to 5.5 mm (supplied ex-works = 3 mm). The setting to the “new” operating point is performed as follows: The plunger must be moved from the “old” to the “new” operating position. Now the set button should be pressed for a duration of 1 sec. The LED now flashes with a higher pulse frequency and the new operation point is set retentively.
