Reliable Detection Layer for Sequence Accuracy and Process Stability
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.
Typical Applications
- Provides stable detection signals to PLC logic
- Improves sequence timing accuracy
- Reduces dependence on mechanical contact methods
- Supports high-cycle production operation
- Enables better fault isolation at machine stations
- Simplifies maintenance through standard sensor families
Buying Checklist
- Repeatable industrial detection behavior

Frequently Asked Questions
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.
