Safety Interlock Switch for Guard Monitoring
The Telemecanique Sensors XCSPL553 is a straight lever operated safety interlock switch designed for machine guarding applications. It features a 1NO/1NC contact form and a NEMA 4, 4X, 12 rated plastic enclosure that is dust tight, corrosion resistant and water tight. The actuator length measures 2.95 in and the body dimensions are 1.18 in high by 1.18 in wide by 7.06 in deep.
Suits Indoor and Outdoor Machinery Guards
This switch suits builders who need a safety interlock with a straight lever actuator for hinged or sliding guards in harsh environments. The IP67 rating and operating temperature range of -13 Degrees to 158 Degrees F support indoor and outdoor use. Buyers who need a different actuator style such as a roller lever or a keyed actuator should look at other models in the range.
Simple Conduit Wiring with Standard NPT Thread
Installation uses a 1/2 in NPT conduit entry for straightforward wiring to the screw terminals inside the enclosure. The switch carries an AC contact rating of 6 A @ 300 V and a DC contact rating of 0.55 A @ 300 V. A common issue is misalignment between the lever actuator and the guard tongue which can prevent the contacts from changing state reliably.

Questions about this item
Does the 1/2 in NPT conduit entry need a matching gland and cable to complete the wiring?
Yes — the switch terminates in a 1/2 in NPT conduit opening, so you must supply a compatible conduit gland and cable to seal the IP67 / NEMA 4, 4X, 12 enclosure.
Can the straight lever actuator reach a guard door that sits 2.95 in from the mounting face?
The supplied lever is 2.95 in long, so it will engage a guard at that distance; if the door is further away you would need a different actuator.
How can I verify the 1NO/1NC contacts change state cleanly when the lever moves?
With power off, use a multimeter on the two contact pairs — one should close and the other open at the same lever travel, confirming the 6 A @ 300 V AC / 0.55 A @ 300 V DC ratings are met.
