Eaton E51KR84 Retroreflector Sensor Accessory

Product Description

The EATON E51KR84 is a retroreflector-type accessory designed for use with photoelectric sensing systems. Retroreflectors redirect emitted light back toward the sensor head, enabling reliable object detection across a defined sensing field. This component is installed by electricians and automation technicians as part of a through-beam or retro-reflective photoelectric sensor assembly. At 0.05 pounds, it is a compact, lightweight fitting suited for integration into control panels, conveyor systems, and automated machinery where consistent optical alignment is required.

The E51KR84 retroreflector is intended for industrial and commercial automation applications. It is commonly paired with compatible EATON E51 series photoelectric sensor heads in machine guarding, parts detection, and process automation setups. Installation typically occurs on fixed mounting surfaces where a stable line of sight to the sensor emitter can be maintained. This accessory suits both new installations and field replacements on existing sensing systems.

Key Features

• Retroreflector-type design returns emitted light directly to the sensor for reliable detection
• Lightweight construction at 0.05 pounds for easy mounting in tight spaces
• Compatible with retro-reflective photoelectric sensor configurations
• Suitable for industrial automation, conveyor, and machine-guarding applications

Compatibility

Designed as an OEM-style accessory for retro-reflective photoelectric sensor assemblies. Refer to EATON documentation to confirm fitment with a specific sensor head model before installation.

Installation Notes

Installation should be performed by a qualified electrician or automation technician in accordance with applicable NEC guidelines. De-energize the associated sensing circuit before mounting or adjusting the retroreflector. Secure the reflector to a stable, vibration-resistant surface and align it precisely with the sensor emitter axis to ensure proper operation. Avoid over-tightening mounting hardware, which can distort the reflective surface.
