The Schneider Square D XCKT2106N12 is a Series XCKT limit switch with a cat whisker actuator — a flexible wire that triggers on contact from any direction. That omnidirectional actuation makes it the right choice for detecting lightweight objects or parts on a conveyor where a lever arm would jam or miss. The 1NO/1NC contact form gives you both a normally-open and normally-closed set in one body, so you can wire a safety signal and a status signal from the same switch. Rated 10 A at 240 VAC for resistive loads; the DC rating drops to 0.27 A at 250 V — that's typical for limit switches, but worth flagging if you're switching a DC solenoid or valve. The IP66/IP67 seal means it handles hose-down and temporary submersion, backed by NEMA ratings 1, 2, 4, 6, 12, and 13 — so it's at home on a washdown line or an outdoor conveyor. UL Listed, CSA, and CE cover North American and European panel approvals.
Mounting and sourcing reality
Surface-mount plastic body with four 0.17 in mounting holes on a 40 mm horizontal center-to-center spacing. Screw clamp terminals — no special tooling needed. The 5.19 in actuator length gives you reach into a confined zone without the switch body itself intruding. No boot included, so if the actuator entry sees direct spray, plan for an external shield or boot.
