The Keyence LR-ZH500N Rectangular Laser Sensor is a high-performance distance-based sensor designed for demanding industrial applications where reliability, durability, and adaptability are crucial. Featuring an impressive detection range of 35 mm to 500 mm, the LR-ZH500N enables accurate object detection over a wide span, making it ideal for packaging, assembly, and logistics environments. Its standard detectable deviation performance ensures consistent results, with deviation values ranging from 9 mm at shorter distances to 50 mm at maximum range, ensuring dependable stability in diverse conditions.

The sensor is equipped with a Class 2 red laser (660 nm), providing a visible and precise detection beam that simplifies alignment during setup and operation. With a compact rectangular design and a convenient 2 m cable connection, the LR-ZH500N can be easily integrated into existing production lines without requiring significant space or structural adjustments. Its built-in 3-digit 7-segment display with clear white output readout, along with output, datum, and spot indicators, allows for straightforward monitoring and calibration on-site.

Performance flexibility is a key advantage of this sensor. Users can select from multiple response times (1.5 ms, 10 ms, or 50 ms) depending on the speed and precision required by the application. Additionally, Light-ON/Dark-ON switching and integrated timer functions (OFF delay, ON delay, one-shot) enable customization for varied detection tasks. With robust protection circuitry, including safeguards against reverse connections, surges, and output overcurrent, the sensor maintains stable operation even under challenging electrical conditions.

Built for rugged use, the LR-ZH500N excels in harsh environments. Its SUS316L stainless steel housing, scratch-resistant PMMA lens cover, and FKM sealing make it highly resistant to chemicals, oils, and frequent washdowns. With an IP68/IP69K enclosure rating and compliance with NEMA 4X, 6P, and 13 standards, it withstands both dust and water ingress, including high-pressure cleaning processes. It is also ECOLAB and Diversey certified, making it particularly suitable for industries such as food and beverage, pharmaceuticals, and chemical processing.

The sensor’s environmental resilience extends further with strong shock and vibration resistance and operation over a wide temperature range from -10°C to +50°C. Its reliability in both indoor and outdoor environments is complemented by its ability to perform under varying light conditions, with high tolerance for both artificial and natural light sources.

In summary, the Keyence LR-ZH500N combines long-range detection capability, robust construction, flexible operating modes, and exceptional environmental durability. It is a highly versatile and dependable solution for industries seeking stable detection performance in even the most demanding applications.
