Photoelectric Retro-Reflective Sensor E3FA-RN11 (M18, NPN, 10-30 V)

This replacement photoelectric retro-reflective sensor is identified by model E3FA-RN11 and is intended for use where E3FA-RN11-style M18 retro-reflective sensors are required. The sensor accepts a 10 to 30 V supply and provides an NPN output. When used with a compatible reflector (for example, E39-R1S), sensing distance is typically in the 0.1 to 4 m range. The M18 cylindrical body fits standard M18 mounts and brackets. Fitment and connector/cable length can vary by supplier and production run; please verify the physical connector, cable length, and mounting requirements against your equipment before installing.

• Replacement for E3FA-RN11: Designed as a drop-in-style photoelectric retro-reflective sensor for equipment that accepts E3FA-RN11-format parts; confirm device fitment before ordering.
• Electrical rating: Operates from 10 to 30 V with NPN output type, suitable for common 10 V class control circuits.
• Sensing performance: Retro-reflective sensing range approximately 0.1 to 4 m when used with an E39-R1S reflector (reflector sold separately).
• Form factor and mounting: M18 (≈0.709 in) cylindrical plastic body intended for standard M18 sensor mounting and brackets.
• Replacement sensor listing; instrument family and connector format stated in the title and specs.
