Applications / Use Case
The Allen Bradley 440N-Z21S17A is ideal for industrial safety applications requiring effective guarding of hazardous zones such as guard doors, gates, and removable panels. Commonly used in manufacturing, material handling, and heavy machinery sectors, the switch ensures machines are only operable when guards are properly closed, enhancing operator protection. Its non-contact sensing reduces maintenance needs compared to mechanical switches, while the stainless steel actuator allows embedding in metal frames, suitable for harsh or washdown environments. This model supports compliance with safety standards and is widely implemented in automated assembly lines, packaging equipment, and robotic safety systems.Related Resources
