1.Machine Guarding in Automotive Production
Automotive plants rely on protective gates and enclosures to keep workers safe from high-speed robotic tools. The coupling relay is used to monitor gate status and disable machine movement instantly when access is detected. With force-guided contacts, the system provides reliable confirmation signals to safety controllers. The slim 22.5 mm housing makes it easy to integrate several relays in crowded control cabinets. This ensures machinery stops safely when gates open, keeping both operators and equipment secure while meeting stringent automotive safety compliance.
2.Hygiene Control in Food Processing Equipment
During cleaning cycles in food plants, machines such as conveyors and mixers must be safely deactivated. This relay ensures that as soon as a sanitation door or access point is opened, power to equipment is cut off. Its three normally open and three normally closed contacts allow simultaneous monitoring and shutdown of multiple circuits. Surge protection safeguards electronics from unstable conditions common in wet environments. With its long mechanical life, it minimizes service interruptions, making production more efficient and hygienic without compromising safety or uptime.
3.Emergency Stop in Packaging Lines
High-speed packaging systems require reliable emergency stop functions to protect operators and reduce downtime during unexpected incidents. The coupling relay supports one- or two-channel control, ensuring redundancy in critical applications. When an E-stop button is pressed, it interrupts multiple enabling circuits simultaneously, shutting down drives and actuators. Its force-guided contacts provide clear diagnostic feedback, simplifying proof testing during routine inspections. Certified to meet safety standards, it guarantees that stop functions operate consistently and predictably, allowing packaging operations to resume quickly and confidently after resets.
4.Automated Logistics and AGV Docking Stations
In modern warehouses, automated guided vehicles (AGVs) must connect and disconnect safely at docking points for charging or loading. The coupling relay ensures that power is only supplied when an AGV is securely positioned, and it cuts off circuits immediately during departure or fault conditions. With both enabling and confirmation paths, the relay handles power switching while signaling operators of docking status. Its compact size makes it suitable for modular cabinets used in logistics systems. Reliable even in environments with vibration or fluctuating conditions, it enhances safety and efficiency in automated logistics.
