Omron E3AS-HL
Photoelectric Sensor
The E3AS-HL Series allows for more precise part differentiation and detection with easy-teach foreground and background suppression. The OLED display on the sensor lets users verify that they have correctly taught the sensor using the single teach button. The E3AS Series also incorporates IO-Link, which shortens the time from design to start-up, reduces troubleshooting and allows for distance output data collection from the sensor.
Key features:
- Small CMOS laser spot or line beam
- Foreground/background suppression (FGS/BGS)
- Single teach button (background teaching, two-point teaching, key locking)
- Predictive maintenance and configuration with IO-Link
- Output monitoring for performance tracking
- Antifouling coating to reduce false detection and minimize cleaning
- Washdown-rated for F&C applications
- Detergent resistance based on Ecolab certification
- Compact body that overcomes space limitations and increases design flexibility
- Easy-to-read OLED display to confirm detection level and threshold setting to reduce error
Advantages of the E3AS-HL
What is CMOS?
- Complementary Metal Oxide Semiconductor
- Each pixel in a CMOS image array has its own amplifier
- Significantly more advanced and more accurate than photodiode/triangulation based sensors
- An alternative to CCD
- Faster read out
- CMOS is becoming more prevalent and is more advanced than photodiodes
Stable detection for challenging parts. The E3AS-HL Series achieves reliable detection of clear, highly reflective, or varying color parts by leveraging CMOS technology.
Small part detection. With a small spot size for 500mm and 150mm sensing distance models, the E3AS-HL Series addresses small part detection for most applications.
Selective detection. Foreground and background suppression allow for window setting and differentiation of desired targets from surrounding parts or surfaces.
Sensor teaching is simplified with a single teach button as well as IO-Link and is easily read via a bright white OLED display showing set vs. actual detection values.
White light OLED display
- Teach confirmation
- Detection level display
- Threshold setting verification
- Output verification
Single teach button
- Use to teach background, foreground, or set a window
Spot Beam
- Small spot has applicability for small part detection – screw heads, caps etc.
- Also applicable for narrow gap detection
Line Beam
- Addresses issues with using a spot type CMOS sensor (triangulation) in grooved surfaces
- Helps to “average” the roughness of a surface
IP69K & Ecolab
- Wash down rated for F&C applications
- Detergent resistance based on Ecolab certification
- Same antifouling lens coating as E3AS-F/L
- Additional environmental protections available
- Face cover
- Air blow attachment
- Applicable in textiles, paper, packaging environments
