4744 - Electric limit switch
The Type 4744 electric limit switch for hazardous areas is designed for attachment to pneumatic control valves according to IEC 60534-6-1.
The limit switch issues a limit signal whenever the valve travel exceeds or falls below a certain adjusted limit, especially when a valve has reached one of its end positions. This signal is suitable for transferring control signals, for example, for activating visible or audible alarms as well as for connecting to centralized control or alarm systems.
