Proximity Switches

Contrinex produces a wide range of proximity switches, including virtually all the common standardized inductive and photoelectric types. However, our specialty is high- performance devices; advanced high performance developed using innovative techniques. That’s why the Contrinex product range stands head and shoulders above the rest.

Subminiature devices with no compromise on electrical specifications.

• The world’s smallest self-contained inductive proximity switch, only 3 mm in diameter and 22 mm long
  
• The world’s smallest self-contained photoelectric proximity switch, only 4 mm in diameter and 35 mm long
• A complete range of other miniature devices to cover all needs
• Devices with very long operating distances
  

The pioneer of devices with very long operating distances, Contrinex has been producing inductive proximity switches for over 20 years. It is the undisputed market leader in this field, as confirmed by its two patented technologies Condist and Condet.

Devices made using Condist technology have operating distances 2.2 to 4 times greater than the standard requires. These are the longest operating distances available on the
market and far exceed anything the competition can offer.

The use of the recently introduced Condet technology permits long operating distances even on non-ferrous metals. In the case of aluminum for instance, they are up to eight times greater than with standard devices.

Severe operating conditions: (high pressure, extreme temperatures, aggressive media)

Two new ranges of proximity switches, one completely sealed and the other pressure-resistant, have recently been made available. Both exhibit outstanding behavior under the most severe operating conditions. Not only that, but they also resist extreme pressure and temperature cycles .

The secret? A new technology from Contrinex which allows perfect seals to be made between metals and ceramics. Highly effective, low cost, and above all, uniform and lasting quality..

Extreme physical robustness, all-metal housings

The most sensitive part of a conventional proximity switch is its sensing face. Unfortunately, it is also where it is the most vulnerable to mechanical damage from moving objects. Even more unfortunately, because it usually needs to be electro-magnetically transparent in order for the magnetic field to pass through, it is generally made of plastic, an inherently weak material. This problem is entirely overcome by using devices made using Contrinex’s Condet technology. They have a one-piece stainless steel housing, sensing face included. Not only does this give greater mechanical resistance, but the seam-free housing also eliminates permeability problems. Two birds killed with one stone!
