The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Schneider Electric - Model: XAL K178 - Condition: Used and in Excellent Condition - Price: $90.00 USD - Availability: In stock, 1 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 2 lb, estimated - Shipping dimensions: 8X8X3 in, estimated ## Categories - Industrial Systems Equipment > Safety and Security > Emergency Stop Devices (primary) ## Details ### Configuration - Enclosure: Plastic - Associated Control and Signaling Units: Harmony XB5 with Plastic Bezel - Number of Cut-Outs: 1 - Material: Polycarbonate - Color: Yellow Lid, Light Grey Base - Degree of Protection: IP 66 - Cable Entries: Knock-Outs - Electrical Block: (2) ZEN L1121, (1) N/C Contact - Pushbutton: (1) ZB5 AS54 Red, Latching, Mushroom Head, Turn to Release, 40 mm Diameter ## Function A manually actuated safety device providing a latching emergency stop. Operator depression of a 40mm mushroom head pushbutton opens a normally closed (N/C) contact, interrupting the control circuit with a positive break action. The circuit remains open until a deliberate 'turn to release' manual reset is performed. Housed in an IP66-rated polycarbonate enclosure, it interfaces with machine control systems to provide a fail-safe stop signal. ## Platform Designed for safety-critical industrial control applications requiring emergency stop functionality in harsh environments. Interfaces via screw terminal connections to safety relays, PLCs, or control circuits through normally closed contact configuration. Knock-out cable entries accommodate n° 13 cable gland and tapped ISO 20. Mushroom head actuator with turn-to-release mechanism ensures positive operator engagement and prevents accidental reset. Commonly deployed in machine control panels, production lines, conveyor systems, robotic cells, and process control stations where immediate equipment shutdown capability is mandated by safety regulations. ## Application Provides critical human-machine interface for immediate, safe shutdown of industrial machinery, automated process lines, and robotics in emergency conditions. Ensures personnel safety and prevents equipment damage by interrupting control circuits via normally-closed contacts. Suitable for harsh industrial environments requiring IP66 ingress protection and robust, latching actuation. ## Images - - - -
