Wenglor OHP551B0003 Laser Distance Sensor High Precision

Description

The Wenglor OHP551B0003 Laser Distance Sensor High Precision operates based on the principle of laser triangulation. By projecting a fine laser beam onto an object and analyzing the reflected light on a high-resolution CMOS line, the sensor determines distances with microscopic precision. This model is specifically optimized for a working range of 40 to 100 mm, offering a linearity deviation of only 0.1%, ensuring that your measurements remain consistent and reliable regardless of target surface changes.

Beyond its accuracy, this sensor is built for the speed of modern industry. With a switching frequency of 1200 Hz and a response time of less than 0.41 ms, it can monitor fast-moving production lines without losing critical detail. The visible red laser light (Class 1) simplifies the alignment process, allowing for rapid commissioning by technical teams. Furthermore, the unit includes an analog output (0…10 V / 4…20 mA) and two switching outputs, providing versatile integration options for various control systems.
