Product Overview

The E3ZG-R81-S 2M is used to deliver repeatable machine-state detection for sequencing, interlocks, and process confirmation. Whether in packaging, handling, or assembly systems, this sensing class helps reduce false triggers and improves control confidence under continuous operation.

Repeatable State Detection

Accurate detection at the right process moment improves sequence integrity and reduces quality escapes caused by timing uncertainty or missed events.

Fit for Demanding Machine Environments

Industrial sensing components are selected for stability under vibration, contamination, and repetitive duty where consumer-grade devices are not suitable.

Faster Commissioning and Replacement

Standardized sensor families simplify spare strategy, reduce replacement errors, and support quicker return to production after maintenance events.

FAQ for E3ZG-R81-S 2M

What's background suppression?
Sensor ignores background objects beyond sensing range. Prevents false triggers from background reflection.
What's the sensing range?
Up to 3m with standard reflector.
Can this sensor detect transparent objects?
Standard retro-reflective: no. For transparent objects, use MSR model.
Can I adjust sensitivity?
Yes, sensitivity potentiometer on sensor side.
