Allen-Bradley 42EF-P2MPD-Y1 Safety Light Curtain

Allen-Bradley RightSight 42EF-P2MPD-Y1 is a 3-meter safety light curtain from Rockwell Automation that guards access to hazardous machines by creating a linear field of infrared beams. When a beam is interrupted, the connected safety system receives a fault signal and can trigger a safe stop or other protective action, helping protect personnel during operation or maintenance. This unit is part of the 42EF RightSight family, which uses modular transmitter and receiver components to form a protective curtain sized to the application. The 3-meter length makes it suitable for medium-distance guarding in production lines where access is restricted along a defined span. As with other RightSight devices, it is designed to integrate with Rockwell safety controllers and relays to deliver compliant safeguarding in environments requiring rapid and reliable responses to beam interruptions. For installation, alignment, and electrical connection details, follow the official Rockwell Automation Safety Products documentation for 42EF-P2MPD-Y1, ensuring proper mounting, clear line of sight, and consistent beam alignment. This model's combination of compact form and a defined guarding length helps manufacturers meet safety standards while preserving productive throughput.
