Good Fit
Opaque or contrast-friendly materials with stable edge conditions.
Sensor
ES201 Infrared Sensor
ES201 is an infrared / visible-beam edge sensor for optical web edge detection in closed-loop web guiding systems. It uses coded-light sensing and is suitable for opaque or contrast-friendly web materials where optical edge feedback is stable.
Key Features
Coded-light edge detection for clear and stable web edge conditions.
- High-frequency coded-light sensing helps reduce the influence of ambient light.
- 11 mm sensing range with 1 ms reaction speed.
- Dust-resistant design for practical production environments, including nonwoven tracking applications.
- Analog output 0–5 V plus two ON/OFF switch outputs.
- Suitable for applications where the material edge can be detected optically.

Selection Notes
Choose the sensor around material opacity and edge condition.
Check First
Transparent, highly reflective or unstable edge materials should be reviewed before selection. For transparent or low-contrast webs, ES100 ultrasonic sensing may be more suitable.
System Match
Use with a compatible web guiding controller, actuator and correction frame selected for the machine section.
Typical Applications
Nonwoven Webs
Edge detection for nonwoven and hygiene material tracking applications.
Opaque Film & Paper
Optical edge sensing for opaque films, paper and contrast-friendly roll materials.
Printing & Converting Lines
Web edge feedback for converting lines where the material edge is optically detectable.
Slitter Rewinders
Edge feedback for unwind, infeed or rewind sections with stable web edge conditions.
Compatible Components
