Product Overview

The Omron E3Z-R61 is a retroreflective photoelectric sensor designed for medium-range detection applications. This sensor offers a sensing distance of 3 meters when used with a retroreflective reflector, making it suitable for a wide range of industrial detection tasks. The E3Z-R61 features a compact and rugged construction with an IP67 protection rating, ensuring reliable operation in dusty and wet industrial environments. The sensor uses an infrared LED light source and features MSR (Mirror Surface Rejection) function, which prevents false detection caused by shiny or reflective backgrounds. The 2M suffix indicates a 2-meter pre-wired cable for easy connection. The PNP transistor output provides compatibility with PLC inputs commonly used in Asian automation systems. The E3Z-R61 is widely used in packaging machinery, conveyor systems, and material handling applications where reliable object detection is required without the complexity of diffuse sensors.

FAQ for E3Z-R61 2M

What is MSR function?
MSR (Mirror Set-up Recognition) uses polarized light to distinguish between the special reflector and shiny objects. This enables detection of reflective targets like metal, glass, and film that would normally pass the beam.
What reflector should I use?
Use Omron E39-R1 or E39-R4 reflectors for optimal performance. Sensing range varies with reflector size: E39-R1 provides up to 4m range.
Can this detect transparent objects?
Yes, with MSR function, this sensor can detect transparent films and glass by detecting the polarization change from the reflector.
What is the sensing range?
Up to 4m with E39-R1 reflector. Actual range depends on reflector size and environmental conditions.
