Safety Relays from Schleicher Electronic

Schleicher Electronic Safety Relays

Innovation and quality bring success.

The EU Machinery Directive stipulates that machinery must not pose any danger. This requires safety concepts that ensure maximum protection for humans and machines on a variety of levels. Safety relays must therefore be easy to use and give a reliable response.

Schleicher safety relays meet the safety standards of DIN ISO 13849 and DIN EN 61062, and fulfil the technical requirements for relay technology with positively-driven contacts in accordance with EN 50205.
