Technical specifications, options and performance data for the CP-PC-2171ELS series general‑purpose compact limit switches.
The CP‑PC‑2171ELS series offers a wide range of general‑purpose compact limit switches with robust aluminum die‑cast construction and IP67 protection. Models include roller lever, plunger, side‑roller plunger, fork‑lever lock and non‑directional types, each available with optional LED or neon lamps, double‑seal, corrosion‑resistant, heat‑ or cold‑resistant options.
The switches meet international standards (UL/CSA, EN 60947‑5‑1, CE) and provide detailed electrical and mechanical performance data, connector options, and life‑cycle ratings for both standard and low‑current loads.
