The Square D Osiswitch XCKJ10541 is a heavy-duty limit switch in a Zamak zinc-alloy body rated NEMA 1/2/4/12 and IP66 — meaning it seals against hose-directed water and dust ingress, suitable for washdown environments and wet-area machine guarding on conveyors or packaging lines. Contact rating is 240 VAC at 10 A and 250 VDC at 0.27 A with an SPDT snap-action mechanism; the AC side handles motor starter coils and solenoid valves, while the DC rating is derated for inductive loads like DC contactors or PLC inputs on smaller control voltages. The rotary head carries an adjustable Delrin roller lever with 23° pretravel and 90° total travel; the 33.3 oz-in operating force and 11° differential travel mean it actuates positively on cam profiles without nuisance tripping on vibration. Connection is via a PG13.5 cable gland with screw-clamp terminals — field wiring without a separate connector, common for panel-side or machine-mounted installations where a hardwired run is preferred. Temperature range is -13 to 158 °F, covering most indoor industrial environments and unheated outdoor enclosures within that span.
Approvals and standards compliance
UL and CSA listed — accepted for North American panel builds and machinery exports to Canada without additional agency review. Designed to EN/IEC 60204-1 (safety of machinery — electrical equipment) and EN/IEC 60947-5-1 (control circuit devices and switching elements), which covers the mechanical endurance and dielectric requirements for industrial limit switches.
