Information About E3S-CT66
The E3S-CT66 from Omron's E3S-C Series is a thru-beam infrared photoelectric sensor engineered for long-distance detection up to 30 meters. This sensor features a rugged zinc die-cast body designed to withstand demanding washdown environments, rated to NEMA 4X, 6P, and IP67 standards. Its 2-meter pre-wired cable allows for easy installation in vertical mounting orientations. The output type is NPN/PNP switch-selectable, giving flexibility for integration into various control systems. The response time of 1 ms ensures fast and accurate detection for applications such as packaging, material handling, or outdoor detection. A 3/4-turn potentiometer allows for adjustable setpoint calibration, and vibration and shock resistance are built-in for consistent operation in industrial machinery.
Key Features:
- Extended Sensing Range: Detects targets up to 30 m away, ideal for long-distance or large-object detection.
- Durable Die-Cast Housing: Zinc metal enclosure offers high resistance to environmental stress, shock, and vibration.
- Selectable Output Configuration: NPN/PNP open collector output can be chosen to match controller requirements without changing hardware.
- IP67 and NEMA 4X/6P Ratings: Designed for harsh industrial and washdown environments with full sealing against moisture and dust.
- Infrared Thru-Beam Sensing: Reliable signal transmission using an infrared light source optimized for precision and reduced interference.
- Fast 1 ms Response Time: Enables use in high-speed processes where rapid object detection is critical.
- Adjustable Setpoint Control: Built-in 3/4-turn potentiometer allows fine-tuning of detection sensitivity.
- Broad Operating Range: Works in ambient temperatures from –25 °C to +55 °C and humidity from 35% to 85% RH.
- Resilient to Mechanical Stress: Withstands vibrations from 10 Hz to 2 kHz and shocks up to 1,000 m/s².
- Prewired with 2 m Cable: Facilitates quick setup and secure electrical connections in industrial systems.
The E3S-CT66 delivers high-accuracy sensing in challenging environments, combining flexible output logic with robust physical protection and long-range capabilities.
