What the SS-5GL1375-ND actually is
A limit switch is a mechanically actuated electromechanical sensor — a plunger or lever physically transfers the position of a moving part (a gate, a cam, a cylinder rod) into an electrical contact change. The SS-5GL1375-ND sits in that class as an Omron subminiature snap-action unit, identified by order code SS-5GL1375-ND on the Limit Switches line.
Where this switch sits in a panel
Subminiature Omron switches of this family mount through a small-diameter panel hole or onto a sub-plate, with the actuator protruding to ride against the moving machine element and the SPDT contact block wired back to the safety or control relay.
