The Square D / Telemecanique XCMD2124L1 is a miniature metal-body limit switch with a retractable steel roller actuator, 1NO-1NC contact configuration, and a 1-meter pre-wired cable. It's rated 240 VAC 1.5 Ampere and 250 VDC 0.1 Ampere — the AC rating handles control-circuit loads on a motor starter or PLC input, but the DC rating is low, so inductive DC loads like small solenoids need careful derating.
Enclosure and deployment
Rated NEMA 4X/6P/12/13 and IP66/IP67, the metal body withstands washdown, hose-directed water, and temporary submersion — suitable for food-processing lines, washdown zones, or outdoor machine guarding where the switch sees moisture or dust. The 1-meter pre-wired cable simplifies panel connection; no separate connector to source.
Operating forces and actuation
Positive-opening force is 12.5 N, tripping force 2.5 N. The positive-opening mechanism (per EN/IEC 60947-5-1) means the NC contact is mechanically forced open when the roller is depressed — a safety feature for interlock circuits where a welded contact must not mask the guard-open state. Spring-return snap action gives clean make/break at an actuation speed of 0.5 m/s.
Carries UL 508, CSA C22.2, CE, and CCC approvals, plus RoHS compliance. Applicable standards include EN/IEC 60947-5-1 and EN/IEC 60204-1.
