Safety interlock switch for machine guarding
The Telemecanique Sensors XCSTE7333 is a solenoid-locking safety interlock switch designed for machine guarding applications. It uses an actuating key to monitor guard position and provides two normally closed safety contacts rated at 6 A AC or 3 A DC at 300 V. The switch operates on a 120 V AC solenoid voltage.
Installation uses 1/2 in NPT conduit entry
The switch connects via a 1/2 in NPT conduit fitting and mounts with a body measuring 1.3 in high, 4.33 in wide and 3.68 in deep. A common issue is misalignment between the actuating key and the switch head which prevents the solenoid from locking or the contacts from changing state. Correct actuator engagement depth is key dependent so the key must be fully seated.
Limits of the NEMA 4, 4X, 12 and IP67 enclosure
The plastic enclosure is rated NEMA 4, 4X, 12 and IP67 for protection against water, dust and corrosion in indoor or outdoor environments. The operating temperature range spans -13 to 158 degrees F. The two normally closed contacts limit the switch to a single safety circuit without auxiliary monitoring contacts.

Questions about this item
How do I verify the XCSTE7333 safety interlock switch is operating correctly after wiring it to the 1/2 in NPT conduit?
Apply 120 V AC to the solenoid and confirm the 2NC contacts open when the actuating key is removed; the 6 A AC rating at 300 V and IP67 seal indicate proper function if the circuit breaks cleanly and the housing shows no ingress.
What components come with the XCSTE7333 and what must I source separately?
The switch body, solenoid locking mechanism, and 1/2 in NPT conduit entry are included; the actuating key is sold separately because its length is key-dependent and not bundled.
Which NEMA and IP ratings should I select for an indoor wash-down area?
Choose the version rated NEMA 4, 4X and 12 with IP67, as these ratings cover hose-directed water, corrosion resistance and dust-tight protection required for wash-down environments.
