Performance Upgrade for R Design Photoelectronic Sensors

The latest generation of wenglor’s R design photoelectronic sensors sets new standards in reliable object detection with proven performance features and simple installation options. The updated product portfolio includes retro-reflex sensors and reflex sensors. In addition to a new teach-in control panel, the new models P1RH reflex sensors with background suppression, P1RK retro-reflex sensors for transparent objects and P1RL retro-reflex sensors universal were equipped with modernized electronics including an IO-Link interface.

The updated portfolio scores points with a simplified operating concept: The sensor housing in R design has been optimized by integrating a central teach button and two LEDs on the top of the sensor. If the button is held down for two or five seconds, objects can be taught in statically or dynamically. In addition to the visual innovations, the sensors also feature modernized electronics including an IO-Link interface. This communication interface allows easy configuration of parameters, output of signal values, condition monitoring and setting of on- and off-delays. The technology is integrated into wenglor’s tried-and-tested R design (56.5 × 26 × 24 mm). This is characterized by an integrated M18 thread, which enables easy installation.
Universal retro-reflex sensors have a range of up to 12,000 mm and retro-reflex sensors for transparent objects reach widths of up to 4,000 mm. The retro-reflex sensors have integrated single-lens optics and enable switching frequencies of up to 2,000 Hz. In contrast, reflex sensors with background suppression work in combination with two-lens optics and a detection range of up to 120 mm. The reflex sensors achieve a switching frequency of up to 1,000 Hz.

Three Different Models and Operating Principles
Reflex sensors with background suppression use red light for contactless and reliable object detection in front of any defined background. Thanks to the principle of angle measurement, the color, shape and surface of the object have no influence on the switching behavior of the sensors. Retro-reflex sensors work with different light sources, whereby the emitter and receiver are located in one housing. If the light beam between the sensor and the reflector is interrupted, this generates a switching signal.
