In long-distance or surrounding hazardous areas such as large conveyor lines, packaging machinery, and printing equipment, traditional emergency stop buttons often cannot cover the entire protective zone. The pull switch (cable pull emergency stop device) triggers an emergency stop by laying a steel cable throughout the entire length of the machine, allowing the operator to pull the cable at any position. The Lifeline 4 series cable pull switch from Allen Bradley is currently one of the most comprehensive products of its kind on the market. It integrates a positive mode locking mechanism, mushroom head emergency stop button, cable status indicator, and multiple sets of contacts, and achieves an IP66 protection level, ensuring reliable operation in harsh environments.
When any switch is pulled or emergency stop is pressed, the corresponding indicator light will light up, and maintenance personnel can locate it within 30 seconds.
The system has reached Category 3, PLd, meets the requirements of ISO 13849-1, and has successfully passed the safety certification.
