SICK i17-SA213 Sensor
SICK i17-SA213 electromechanical safety switch, i17S family. Positive-opening guard monitoring for hinged machine doors.
Overview
The SICK i17-SA213 is an electromechanical safety switch of the i17S family. Mounted on movable machine guards, it reports the guard position to the safety circuit and locks attention on positive-opening actuation, helping ensure that machines can only run when guards are closed.
How It Works
The switch is actuated by the movement of the hinged guard. Its positive-opening contacts open mechanically when the guard opens, interrupting the safety circuit regardless of the contact state. This direct opening action is the core principle of electromechanical guard monitoring.
Key Features
- Electromechanical safety switch for hinged guards
- Positive-opening contacts for reliable circuit interruption
- Compact housing for direct guard mounting
- Robust construction for industrial guard duty
- Simple integration into safety circuits
- Suitable for machines without guard locking requirements
Typical Applications
- Monitoring of hinged machine guard doors
- Position monitoring of safety flaps and covers
- Guard monitoring on packaging machinery
- Access doors on production machines
- Safety gates on processing equipment

Installation and Setup Notes
Mount the switch on the machine frame and the actuator on the guard so the contacts open positively when the guard opens. Wire the contacts into the safety circuit with dual-channel evaluation where required, and test the function with guard opening at every commissioning and maintenance interval.
Frequently Asked Questions
Does it provide guard locking?
No, the i17S monitors guard position; guard locking requires locking safety switches.
What is positive opening?
The contacts open through a mechanical movement of the guard itself, independent of springs, ensuring the circuit opens when the guard opens.
How is it evaluated?
Through safety relays or safety controllers with dual-channel input evaluation.
