Slack Cable Switch (SCS)

Slack cable switches are used to detect the suspension tension on vertically moving doors. These stop the motorized drive as soon as the door movement is obstructed, e.g. if the suspension cable slackens.

Support Request

The minimum protection level for slack cable switches required by EN 12453:2017+A1:2021, Cat. 2 PL "c", is guaranteed by the design. The SCS slack cable switch combines a compact, cylindrical design with a diameter of only Ø 40 mm with a double, safely guided compression spring of high mechanical strength and a protected positive break contact. The unavoidable elongation of the cables after reassembly can be easily detected from the outside and adjusted without opening the switch.
