Emergency Stop Device with OSSD (ES-P-Z)

The ES-P-Z is a highly visible, reliable emergency stop button designed for industrial safety. Its durable yellow polyester housing ensures impact resistance and visibility, while the replaceable contact block supports long-term maintenance and sustainability.

The switch features pulsed OSSD outputs for seamless integration with safety systems, supporting up to 30 interconnected Z-Range devices. A raised bi-colour LED indicator enhances fault diagnostics, improving visibility and minimizing downtime with clear visual alerts, even at a distance. An auxiliary output provides additional diagnostic flexibility.

For added safety, a special lid trip mechanism ensures that removing the lid opens the safety contacts. The ES-P-Z is rated to IP67, making it suitable for wet environments.
