The actuators from the RAFIX 22 FS+ series are designed for 22.3 mm mounting holes according to IEC 60947-5-1. All actuators are equipped with a locating pin. When dealing with PCB switching elements, this pin ensures the fitting accuracy of the actuator as well as the switching element and is therefore indispensable when designing systems with these switching elements. The design principle permits a minimum grid spacing of 30 x 30 mm. As a result, actuators with a square collar are arranged next to each other. Potential external lettering (e.g. in the form of identification strips in the front panel) must be taken into consideration when designing the grid spacing. The PCB is mounted on the front plate using threaded bolts for the system configuration.
