Frequently Asked Questions
What's the difference between through-beam and diffuse-reflective types?
Through-beam detects up to 40m with best anti-interference performance; diffuse-reflective requires no reflector and is designed for short-distance (≤3m) close detection applications.
Can it work in high dust/oil environments?
Yes, IP67 protection provides dust and water resistance, making these sensors suitable for workshop and battery production harsh environments.
Why does false detection happen sometimes?
Most false detections result from light axis misalignment or strong ambient light interference. Properly align the light axis and utilize the anti-interference mode to resolve this issue.
Is it compatible with NPN and PNP PLCs?
Most models (E3Z/E3ZG series) support both NPN and PNP output configurations, eliminating the need to replace sensors when switching between different PLC types.
How to debug the sensor quickly on site?
Use the one-click teaching function by long-pressing the button for 2 seconds - the sensor will automatically set the optimal detection threshold.
Can it detect transparent objects like plastic film?
Yes, TOF series (E3ZG) can reliably detect transparent and reflective objects without false triggering.
What's the operating temperature range?
Operating range is -40℃ to +55℃, ensuring stable performance in low-temperature freezers and high-temperature workshop environments.
How to solve the problem of short detection distance?
Check for dirty lenses (clean if necessary) or light axis misalignment. Proper alignment will restore standard detection distance.
Does it support IO-Link for data monitoring?
E3ZG and E3S advanced series support IO-Link, enabling real-time monitoring of detection status and equipment data.
What's the service life of the core components?
LED light sources and core components have a lifespan exceeding 100,000 hours, resulting in low failure rates and minimal maintenance requirements.
