Sensor/Actuator Passive Distributor. Push-Pull, M12, bayonet lock with rear spring strip. While in the standard M12 system the rotating sleeve is complicatedly screwed on and hindered by the vibration protection, Push-Pull works with a click, similar to the well-known garden hose connection systems. The audible locking ensures a secure and reliable connection as well as high tightness. The new SAI Push-Pull distributors can be used both with M12 connectors and with the new Push-Pull connectors.
