Product catalog summary
Overview
BERNSTEIN AG provides a range of coded magnetic switches designed for safely monitoring doors, flaps, and hoods. These switches are particularly useful in applications requiring position sensing and offer enhanced security due to their coding, which prevents operation with standard magnets.

Specifications
The magnetic switches are equipped with two channels: one normally open and one normally closed contact. This configuration minimizes the risk of simultaneous failure of both safety circuits due to external influences. The switches comply with EN 14119 and EN 60947-5-3 standards for type 4 interlocking devices and require connection to a suitable evaluation device.

Product Features
  • Compact design
  • No external moving parts
  • Low susceptibility to non-metallic dust and liquids
  • Easy to clean
  • Conditional tolerance to misalignment of the guard


Technical Data
The switches have a maximum switching voltage of 170 V DC / 120 V AC, a maximum switching current of 400 mA DC / 280 mA AC, and a mechanical lifespan of 3 x 108 operations. They are designed to operate at a frequency of 1 Hz and have a repeat accuracy of 0.1 x S.

Applications
These magnetic switches are ideal for environments with high cleanability requirements and can be used in various configurations with different cable lengths and connectors. They are suitable for achieving PL d and SIL 3 safety levels when connected to a BERNSTEIN evaluation system.

Evaluation Systems
BERNSTEIN offers two evaluation systems (MÜZ-102/D24-FL-DA and MÜZ-202/D24-FL) that monitor the correct switching of the magnetic switch channels. These systems ensure compliance with DIN EN 60947-5-3 and provide an EC type-tested solution for safe monitoring of movable guards.

Contact Information
BERNSTEIN AG is headquartered in Porta Westfalica, Germany, with international branches in Denmark, Austria, Switzerland, Hungary, France, Italy, the United Kingdom, and China.

Coded Magnetic Switches-2

Coded magnetic switches for various applications Safety switches are usually used for the safety-related monitoring of doors, hoods and flaps. But due to other requirements, such as environmental conditions or the complexity of the application, it may be necessary to switch from a mechanical safety switch to another technology, such as coded magnetic switches. Our magnetic switches are sensors with a two-channel output. In order to meet the requirements of EN 14119 and EN 60947-5-3 for a type 4 interlocking device, this output must be connected to a suitable evaluation device. To make it more...
