The RM525 has a strong brass/nickel plated housing, but is only 24mm long. The switch has an M5 threaded body and locking nuts which enables the switch to be finely adjusted to a suitable operating distance. The contact form is normally open and rated at 100Vac, 0.25A, 3VA with 300mm cable for easy termination. A button magnet can be supplied with the switch. This switch is useful for a wide range of position sensing applications and its small size and fully threaded body makes it useful for fine setting in control and process applications.
