Magnetic switch

BERNSTEIN offers the user coordinated coded magnetic switches and corresponding actuators. With suitable evaluation (e.g. BERNSTEIN MÜZ), the sensor fulfils the requirements of DIN EN 60947-5-3 and is therefore suitable for safety-related monitoring of doors, Protective guards and flaps in accordance with DIN EN 14119 and DIN EN 13849. — Manipulation protection through coding (multicode) — Redundancy through NC and NO contacts — Cannot be operated with conventional magnets — Cable versions in 3m, 6m and 9m or plug version — Sturdy plastic enclosure

We offer a large standard assortment of high-quality tactile short-stroke switches or micro switches and micro switches. The switches and pushbuttons are characterised by a high level of workmanship and a long service life (up to 1 million cycles). The microswitches are used in medical technology, industry, entertainment technology and in the automotive sector and are suitable for PCB assembly. They are supplied on a roll. If your desired specification is not available in our standard range, please feel free to contact us at any time. Completely customised developments are also possible.

In order to meet the demands for robustness and efficient heat output, we have embroidered the heating element on a glass mesh fabric carrier material. Between the meandering arrangement of the heating strands, we integrate a recess for the temperature switch in the CAD layout. In addition, a second wire is laid concurrently as a PTC thermistor for the electrical connection of the safety switch. After the technical embroidery process, the safety switch is inserted and connected by our company’s respective department. Each prefabricated element is tested for functionality and performance in the final inspection and is delivered to the customer after passing the test. As a semi-finished product, the infrared heating element on glass mesh fabric can be further processed by the customer, e.g. in connection with silicone, rubber or epoxy resin.

The electronic temperature switch of BEDIA is fitted with thin-film resistor Pt 1000 in a bridge circuit. This sensor element provides close switch point tolerances and a quick response. Switch point and reset hysteresis may be selected within the admissible operating range when ordering so as to allow the monitoring of both very wide and very close temperature ranges. The switching output is protected from short-circuit and overload. The short-circuit current is limited by the output transistor switching off inthe event of a fault. It will automatically reset as soon as the fault has been remedied. The switch is available with ground-connected, plus-connected or potential-free DC switching output. The switch is open in the event of power failure or disconnection of the power supply, independed of the switching function. It is available both as normally open (NO) or normally closed (NC) switch.
