Telemecanique XAL-K174 Pushbutton Emergency Stop

The Telemecanique XAL-K174 emergency stop control station is built around a 40 mm red mushroom-head pushbutton with turn-to-release operation and a single normally closed contact for immediate machine stopping. Designed for Harmony XALK systems and compatible with Harmony XB5 Ø22 mm control and signaling units, it mounts via surface installation in a polycarbonate enclosure with a yellow cover (RAL 1021) and light grey base (RAL 7035). Electrical ratings include a 600 V rated insulation voltage and a 6 kV rated impulse withstand, with a conventional thermal current of 10 A and a rated operating current of 6 A at 120 VAC (AC-15) or 3 A at 240 VAC (AC-15); the contact configuration is 1 NC with slow-break operation. The device is intended for machine safety across conveyors, packaging lines, machine tools, production equipment, and industrial automation systems, making it a common choice for maintenance teams, OEMs, and system integrators in replacement or retrofit projects. With IP66 protection, surface mounting, a -25 °C to +70 °C operating range, and 300,000 mechanical cycles, the XAL-K174 provides a solid emergency stop solution within the Harmony XALK family.
