Omron has developed a variable adjustable actuator limit switch that meets the requirements of the EN81-1 lift standard that was introduced in January.
The D4D-152NH maintains a positive opening mechanism (as required by the standard) by virtue of its improved grooved actuator arm. Should the holding screw come loose, the new arm keeps its position and maintains the positive opening function of the switch.
A rubber roller on a resin ring is used to give added strength to the actuator head.
