1. Product Title

A‑B 440L‑R4F0018‑Q‑ GuardShield Safety Light Curtain Receiver

2. Product Overview

The 440L‑R4F0018‑Q is the receiver unit for Allen‑Bradley GuardShield safety light‑curtain system, designed for personnel safeguarding on automated machinery. Paired with a corresponding transmitter, 440L‑R4F0018‑Q creates an infrared sensing barrier to detect human body intrusion into hazardous machine zones, triggering safe‑stop signals to machine control circuits. This unit supports fixed sensing resolution, integrated OSSD safety outputs, and robust immunity against optical interference from factory‑floor lighting. Compact housing fits machine‑guard mounting profiles and complies with global machine‑safety standards for production‑line risk mitigation.
