HOKUYO PEY-155C Flexible High Precision Lidar Proximity Sensor For Precision Assembly Lines

1. Precision Detection with Advanced Optical Technology

The PEY-155C is a high-performance industrial optical sensor engineered for critical automation applications, designed to deliver reliable detection in dynamic manufacturing environments. Equipped with infrared (IR) through-beam technology and a 950nm wavelength LED, it achieves precise object detection with a maximum sensing range of 5 meters . Its background suppression function eliminates interference from reflective surfaces, making it ideal for sorting applications in logistics or semiconductor assembly lines. The sensor incorporates auto-tuning algorithms to maintain stable performance across varying ambient light conditions (up to 10,000 lux), ensuring consistent operation in both indoor and outdoor settings. A high-speed response time (<1ms) enables real-time monitoring of fast-moving conveyor belts or robotic arms, while the dual digital outputs (NPN/PNP) provide flexible integration with PLCs and motion controllers.

2. Rugged Design for Harsh Industrial Environments

Encased in an IP67-rated ABS housing, the PEY-155C withstands dust, water submersion (up to 1m), and extreme temperatures ranging from -20°C to +60°C . This robust construction ensures operational resilience in harsh environments such as automotive paint shops or food processing plants. The sensor’s adjustable sensing angle (15° vertical/30° horizontal) simplifies alignment in confined spaces, while the screw-mounting brackets enable quick installation on machinery or conveyor frames. A multi-color LED indicator provides real-time feedback on power status, signal strength, and fault conditions, reducing downtime during maintenance. Compared to competitors like Keyence’s CX-411 or Omron’s E3Z-LS63, the PEY-155C offers 30% faster response time and 2x higher ambient light tolerance, making it a cost-effective choice for high-speed production lines.

3. Flexible Integration & Industry-Compliant Performance

The PEY-155C supports SEMI E84-compliant communication protocols, ensuring seamless integration with automated material handling systems in semiconductor fabs . Its teachable function allows operators to quickly set detection thresholds via push-button controls, reducing setup time by 50% compared to traditional potentiometer-adjusted sensors. The sensor’s 2m pre-wired M12 connector enhances connectivity reliability, while the reverse polarity protection safeguards against wiring errors. Widely adopted in packaging, automotive, and electronics industries, the PEY-155C exemplifies HOKUYO’s commitment to precision-engineered, future-proof automation solutions. For applications requiring higher precision, HOKUYO offers the PEY-155C-HD variant, which incorporates laser triangulation technology for submillimeter-level accuracy in quality inspection processes.
