4740 - Electric limit switch

The Type 4740 electric limit switch is designed for attachment to pneumatic control valves of type 3353, 3354, and 3379.

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.
