The GEMÜ 1242 is designed to be fitted to a GEMÜ valve in order to detect the position of linear actuators optically and elec-
trically. The product has a microprocessor controlled intelligent position sensor as well as an analogue travel sensor system
(potentiometer) and is connected in a force-locking way with the actuator spindle by means of a mounting kit (spring, operat-
ing bush). The valve end positions and the integrated travel sensor can be controlled via the electrical connections.
