Versatile Retro-Reflective Sensing for General Automation
The E3JK-RR12-C provides reliable object presence detection using reflector-based optical sensing. It is commonly selected for conveyor detection, package flow monitoring, and part transfer stations where easy alignment and durable operation matter.
Retro-Reflective Detection Principle
The sensor emits light toward a reflector and monitors returned signal changes when an object interrupts the beam path. This method offers practical setup for many line-of-sight detection tasks.
Rugged Daily-Use Performance
Its industrial body and sealed construction support deployment in packaging, assembly, and material handling equipment where dust and vibration are routine.
Simple Integration with PLC Inputs
Output wiring is designed for standard digital input architectures, enabling fast replacement and predictable commissioning in control panels.
Typical Applications
- Triggers machine sequence when product arrives
- Detects gaps between moving objects
- Improves repeatability versus mechanical flags
- Supports non-contact monitoring in dusty zones
- Enables faster cycles with stable sensing
- Reduces maintenance from contact wear devices
Buying Checklist
- Flexible retro-reflective sensing for many setups
- Industrial durability for continuous operation
- Easy PLC integration and replacement workflow
- Good fit for conveyor and packaging tasks
- Omron sensor ecosystem compatibility
