Bernstein Sensors

Bernstein has grown through a long and eventful history to become a world leading manufacturer of sensor technologies. Founded by the Bernstein brothers Hans and Herbert during the Weimar Republic, the company was originally called “Monopol” and manufactured low voltage products for electrical building services control systems. After the end of the Second World War, Hans Bernstein moved to West Germany, and launched the company that would grow into the Bernstein group. Making a name for itself as a manufacturer and distributor of electromechanical components for signal acquisition and pre-processing, Bernstein has been closely involved in all the most important technological developments for today’s industrial safety technology.

Today, Bernstein ranks among the world’s leading providers of industrial safety technology. In-depth market knowledge, close proximity to end users, and years of experience in mechanical engineering and electronics is reflected down to the last detail in Bernstein products.

Bernstein products are used throughout all branches of industry. In addition to classic plant and machine construction, they are utilized in the lift construction, automotive, agriculture, conveyor construction, automation engineering, wood-working, renewable energy, medical technology, AS-Interface and ATEX industries.

As a company, Bernstein always has an eye on the future. They are constantly innovating, taking in current technological trends as well as providing answers to questions of ecology and economic efficiency. Bernstein states that their objective is to actively influence technical innovation and modern application solutions. This pioneering attitude keeps them at the forefront of the sensor technology industry and Long Distributors are proud to stock their product range.

Bernstein’s comprehensive range of switches, sensors, enclosures and operator terminals offers customers effective and versatile solutions. By conforming to international safety guidelines,  products perfectly integrate in existing systems. This makes them a flexible and adaptable, as well as excellent quality, solution for manufacturers who want the very best.

Bernstein’s electro-mechanic switches provide an excellent and reliable switch solution for your system’s requirements. They are characterised by a convincing price-performance ratio and by a high reliability at different stages of voltage.

The products range from plastic-bodied limit switches, metal-bodied limit switches and foot switches to safety switching devices. The AS-i compatible switches reduce time and costs in reference with the assembly, the materials and the operation.

A vast range of types, sizes, switching functions and actuators allow nearly every application, so you are sure to be able to realise your system’s potential with switches from Bernstein.

Bernstein are leaders in the field of industrial foot switches. They have incorporated more than 50 years of experience into the development and production of their products, and this is reflected in the quality and utility of their foot switches. The wide range of models shows the specialisation of the company in foot switch solutions for different applications.

Resistance, extremely long life and mechanical stability are characteristic features of all Bernstein products, and underline Bernstein’s market position as the leading provider of industrial foot switches.

Whether on the production line or at the machine, for maximum safety in a company’s production area, rope pull safety switches provide a proven and reliable technical solution.

SRM rope-pull safety switches from BERNSTEIN can be deployed anywhere, are easy to install, and very straightforward to use.

Standard Rope Pull switches

These cable pull switches are used exclusively as safety command devices. Their high specifications are governed by strict safety standards, so you can rely on them to provide a safe and effective health and safety solution. These switches are available in metal enclosures as well as in insulation-enclosed versions. They are operated manually by pulling on the attached cable.

The basic design of the standard rope pull switches is based on that of position switches.

In general, inductive proximity switches consist of four basic elements: a coil, an oscillator, a threshold switch and an output stage with short-circuit protection.

The oscillator generates a high frequency, electromagnetic alternating field which is emitted from the active face of the coil.

Eddy currents are induced in a metal object that enters this field. These eddy currents draw energy from both the electromagnetic field and from the oscillator which is consequently attenuated.

The more energy taken the closer the metal object moves towards the active face. The threshold switch switches on the output stage at a defined attenuation value.

In proximity switches with a DC voltage supply, this switch is designed as an NPN transistor which switches the connected load to the negative pole, or as a PNP transistor which switches the load to the positive pole. The output stage is a thyristor or a triac in AC voltage switches.

Capacitive proximity switches detect conductive and non-conductive materials that can be in a solid or liquid state. They serve the purpose of monitoring product levels in containers, checking contents in filling and packaging systems as well as detecting, positioning, monitoring and counting objects, e.g. in sequence control systems, conveyor belts.

Bernstein offers electromechanical reed contact magnetic switches, as well as electronic versions which operate according to the Hall and magnetoresistive principle.

The electronic versions are characterised by their enhanced mechanical properties (extremely high resistance to vibration, shock or impact) and are not prone to wear in operation. Thanks to the use of only one single “active” component (reed contact), “traditional” electromechanical magnetic switches are extremely reliable in operation. The universal current capability and low procurement costs allow these switches to be used in a wide range of applications.

Bernstein’s tradition of excellence as well as their outlook of innovation means their products are a world-leading solution for all your sensor and system automation needs.
