| The outstanding feature of the Contrinex series 700 inductive proximity switch is its one-piece stainless steel housing which, at one fell swoop, manages to eliminate the most critical weakness of this type of device. Forget damaged plastic caps, forget breakdowns due to inadequate sealing; they are things of the past! These switches are also exceptional in having very long operating distances, for instance 6 mm for the size M12 embeddable version. As a further bonus, these operating distances are also achieved on non-ferrous metals, e.g. aluminum and brass. These improvements result in completely new application possibilities for traditional inductive devices, without having to forego any of their advantages. In all others ways, they are normal proximity detectors with the usual data and protection functions. Embeddable and non-embeddable versions in sizes M12, M18 and M30 are available immediately. |

| All the electronic sensors work on a non-contacting basis using industrial magnets - this includes Hall and magnetoresistive sensors. The exceptions are the gear-wheel sensors which use a ferrous gear-wheel. The advantage of magnetoresistive sensors is that the same sensor, a standard small model, can be used for different operational distances. The operational distances which can be achieved depend only on the strength of the magnet used. All the models can also be delivered with non-wearing Hall sensors. Besides the various standard models, we also manufacture customised housings to your requirements. |

Non-contact magnetic detection proximity detector produces a digital output. The output produced by Hall-Effect Proximity Switch sensor switches between logic low (operate point) and logic high (release point) with presence and absence of a magnet as a target. The difference between the magnetic operate and release points is called the hysteresis of the device. The built-in hysteresis circuitry allows clean switching of the output even in the presence of external mechanical vibration and electrical noise.

|
| The range includes different size devices for operating pressures from 100 to 500 bars. Their main applications are in high-pressure hydraulic systems. They feature a stainless-steel housing imperviously shrunk onto a ceramic disk at the sensing face. |

For demanding applications in high-temperature areas, inductive proximity switches with good long-term reliability have become increasingly popular. Contrinex offers a series of embeddable and non-embeddable HT switches in sizes M8 to M50. The devices have operating distances from 2 to 25 mm, and are respectively suitable for applications up to 140°C, 150°C, 180°C and 230°C.
The executions for 140°C, 150°C and 180°C feature built-in amplifiers. Connections by means of a 2 m silicone or Teflon cable is standard. Other cable lengths and types are available on request.
For 230°C types, the amplifiers are built into an M12 stainless-steel housing, which is connected by means of a standard 2 m Teflon cable, and thus removed from the hot area. This cable carries a pure DC, rather than a high-frequency signal, and its length can thus be chosen freely, without having a negative influence on the switching behavior of the device, and without the need for adjustment. Connection of the amplifier is by means of a 2 m PUR cable.
All the usual protection functions, such as short-circuit, overload and voltage-reversal protection are built in. Furthermore, the devices feature good protection against environmental influences (IP 67). |

A proximity switch is a device which causes a switching action without physical contact. SCHMERSAL proximity detectors respond to targets that come within the active range of their generated sensing fields. These units are completely self-contained, and house a field industrial generator, amplifier, and other necessary circuitry to accomplish electronic switching.
The units are all solid state and have no moving parts that can wear out. The electronic switches are not susceptible to contact contamination, contact erosion, or material transfer as are mechanical switches.
Their service life, within their specified ratings, is virtually unlimited. The switching is insensitive to vibration, and is positive (full step function) without chatter, regardles of how slowly the target approaches or recedes from the sensor |
|
Inductive proximity switches are designed for wear-free and non-contact detection of metal objects. For this they use a high-frequency electro-magnetic AC field that interacts with the target.
Moreover uprox+ detection offer highest switching disntance with their unique professional coil concept, factor 1 and highest operational safety from the start by simple and safe mounting. |

| These new Contrinex size M8 analog detection are distinguished by their unusually large sensing range from 0 to 4 mm with, at the same time, excellent temperature stability between -25°C and +70°C, as well as outstanding repeat accuracy. Thus, the distances achieved using these devices are far in excess of those achieved with conventional standard detection where, in order to obtain similar detection values, a model with a diameter of at least M18 would have to be used. In addition, since intermediate digitization has been done away with, the resolution of the Contrinex devices is virtually unlimited. The use of analog sensor technology permits the realization of numerous applications. For instance, the regulated approach to end positions at minimum cost, the realization of several switch points with a single device, monitoring concentricity or the detection of vibrations. The switches are available with output voltage ranges of 0 … 5 V or 0 … 10 V. As a result of the non-linearized transfer function, the Contrinex devices are inexpensive but nevertheless efficient. Contrinex inductive analog sensors are also available in sizes M12, M18 and M30. |

| There has always been an industrial demand for small and reliable proximity switches with very long operating distances. Thanks to the CONDIST® technology, developed and patented by the innovative Swiss company CONTRINEX, inductive proximity switches with quadruple operating distance have been launched onto the market. These switches guarantee all functionalities with operating temperatures of -25 °C ... +70 °C. They are manufactured according to the strictest quality standards, and present the user with a wide range of technically interesting and economically advantageous application possibilities. Largely compatible with standard proximity switches, they are particularly suitable for targets which are normally difficult to detect, such as small or narrow objects, non-ferrous metals, wires, etc.. The range includes N.O. and N.C. types, PNP or NPN executions, as cable or connector versions. Available in sizes M8 and M12, the devices are quasi embeddable, and contain all important protection functions, such as short-circuit protection, EMC and polarity-reversal protection. |

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.
