Azbil SL1-EK Compact Horizontal Limit Switch

Azbil SL1-EK Compact Horizontal Limit Switch is a rugged, space‑saving end‑of‑travel sensor for industrial automation, built around a long roller plunger actuator that provides precise actuation in tight installations. This low‑load variant uses SPDT contacts (1NC/1NO) with standard‑load pure silver rivet or low‑current gold‑plated rivet configurations and M3 screw terminals for reliable wiring. The unit is IP67 sealed with an oil‑resistant/immersion‑proof design that includes an O‑ring and a built‑in diaphragm seal to prevent coolant and dirt ingress. The SL1 family is engineered for longevity, delivering up to 20 million mechanical operations thanks to a two‑piece spring mechanism, and offers high sensing fidelity with a movement differential of 0.1 mm and a maximum operating force of 11.8 N. For the EK variant, key travel figures include a maximum pretravel of 1.5 mm and a minimum overtravel of 3 mm, ensuring predictable actuation even where clearance is limited. The compact body supports tight gang mounting on control panels or machine frames and is suitable for end‑of‑travel detection in conveyors, packaging machinery, and other automated equipment. Where available, models bear UL/CSA/CE/CCC markings, confirming compliance across multiple safety and standards regimes.
