Welcome to the world of sensors Crafted by Contrinex

Sensors are about detecting movement. Movements, which can be of a complex nature, and which occur for instance in machine components of automated production processes. Keeping track of these movements is necessary in order for the machines to function smoothly, both independently and in relation to each other.
Enormous amounts of information concerning movement and position need to be passed to and from the main control unit. And this in working environments that frequently mean dirt, oil, vibrations, and high temperatures.

Contrinex sensors reliably deal with the most critical demands for information. Efficiently, effortlessly, and under practically all working conditions.


A sensor manufacturer unlike any other Contrinex is a leading manufacturer of inductive and photoelectric sensors. The Swiss company, with headquarters in Givisiez, has developed a unique range of products whose performance far exceeds that of standard devices. Since its foundation in 1972, Contrinex has grown from a one-man concern into a small multi-national Group employing over 500 people worldwide. However, it still concentrates exclusively on the development, manufacturing and sales of sensing equipment for industrial applications.

In particular, Contrinex has specialized in:


- miniature devices
- long operating distances
- resistance to extreme environmental conditions
- devices in all-metal housings


Sensors for peak performance Contrinex produces a wide range of sensing equipment, including virtually all conventional standardized inductive and photoelectric sensors. However, the Contrinex specialty is high-performance devices. Advanced high performance developed using innovative techniques, i.e.

All-inclusive inductive and photoelectric miniature sensors

Inductive sensors with up to 4-times operating distances

Inductive sensors for tough operating conditions, i.e.


- Mechanically and chemically rugged all-metal sensors
- Sensors for permanent pressures up to 500 bar (peaks 800 bar)
- Sensors for operating temperatures up to 230 °C
- All-metal sensors for food industry (IP 68 & IP 69K)
- All-metal sensors for sea-water applications (IP 68 & IP 69K)


Photoelectric sensors with background suppression

Production is one thing to design high-performance sensors, but it is another thing to produce them. The quality must be impeccable, while production costs must be kept within reason.

Whereas automation is used wherever possible, highly trained employees with good eyesight, steady hands, concentration, and strong nerves are irreplaceable. For example, the assembly of miniature devices demands extraordinary dexterity, which not everybody possesses. Another example is the assembly of sensors with long operating distances, where high process reliability and uniformity is a prerequisite for consistent parameters of the final product. Thus, the selection and training of suitable employees is extremely costly and time-consuming.

Only the most recent production technology is used in assembling Contrinex's high-tech products. Our techniques include printed ASIC technology, SMD assembly, die and wire bonding of semi-conductor chips, plasma surface treatment, vacuum potting, and ultrasonic welding. And these are just a few of the key words.

The old saying, “If you want a job done well, do it yourself”, is particularly true where perfection is concerned. In order to ensure constant quality of critical production processes, Contrinex has therefore chosen to have a high degree of self-sufficiency.

If Contrinex sensors are held in high regard by a worldwide demanding clientele, it is not only because of their technical performance, but also because of their uncompromising quality and reliability. The latter is achieved by involving all departments and all management levels in our ISO 14001:2004 and ISO 9001:2008 certified management systems.

The strictest quality standards are applied to the manufacture of every Contrinex sensor. Nothing is left to chance. Only suppliers who also manufacture to the highest quality standards are qualified to deliver components. Before each component is released into production, it must pass our rigorous incoming inspection. At each production stage, intermediate testing is carried out. And before packing, highly developed automatic systems perform a comprehensive test on every switch, where all important parameters are checked, documented and statistically analyzed. In addition, the entire manufacturing process is set up for full traceability using the most up-to-date computer technology. The consistent high quality of Contrinex sensors is certainly not just the result of pure coincidence
