The Safety Switch with Separate Actuator by Schmersal is engineered for secure monitoring of sliding, hinged, and removable safety guards in industrial automation systems. These switches consist of two separate components: a switch unit mounted on the machine and an actuator installed on the guard.
When the guard is closed, the actuator aligns with the switch, enabling machine operation. If the guard is opened, the actuator separates from the switch body, causing the normally closed (NC) contacts to open and interrupt the safety circuit, ensuring immediate machine shutdown.
Unlike integrated safety switches, this design offers greater flexibility for installation, especially in applications where guards are frequently opened or removed for maintenance, setup, or material handling.
These switches are widely used across industrial machinery due to their simple yet highly effective safety principle, ensuring that hazardous machine operations are stopped instantly when access points are opened. They can also be easily retrofitted onto existing equipment or mounted on standard machine profiles, making them ideal for upgrades and modernization projects.
Schmersal safety switches are built with robust metal or thermoplastic enclosures and offer high protection ratings (minimum IP67), ensuring reliable operation in harsh environments with dust, moisture, and vibration.
When integrated with safety relays or monitoring modules, these switches can achieve high safety performance levels (up to Category 3/4 or PL d/e as per ISO 13849-1), making them suitable for critical safety applications.
