The position limit switch series Sigma particularly impresses with its modern design. It is designed and developed for heavy industrial areas within the crane and conveyor sector.


The housing is manufactured of a robust self-extinguishing plastic mixture. The high wall thickness of the housing provides an enormous stiffness and in addition all installation parts are fixed by use of many screw connections.


The position limit switch series Sigma is manufactured in different executions. Beside the version for simple direction-dependent switch-off via 2 contacts there is a version available with 4 contacts for a 2-stage switch-off per direction.


All materials in direct contact with the environment are resistant against atmospheric agents, oils and extreme temperature changes. The rubber gaskets ensure optimal protection against dust and liquids, thus the protection degree of IP 65 is easily reached. The optimized internal space allows a quick and easy cabling.
