Cylindrical photoelectric sensors from SICK Automation

March 2013 Sensors & Transducers

GR18S is the new SICK Automation family of cylindrical photoelectric sensors. The compact housing design and choice of axial or radial optics provide particularly space-saving solutions with wide sensing distances and ranges.

Whether in the form of a proximity sensor in various sensing distances, a retro-reflective sensor, or a through-beam sensor – all sensors are available in five unique, space-saving designs. When space is at a premium, radial sensor design provides specific options to solve the application. Although space-saving, these sensors are still powerful: the proximity sensor offers a sensing distance of up to 550 mm, the retro-reflective provides a range of up to 6,5 m and the through-beam alternative is equipped with a sensing range of 15 m.

Robust sensors encased in metal, plastic and as a ‘fully flush’ option.

GR18S sensors are available in housings with IP 67 protection and M18 thread housings made of reliable plastic or metal. In the ‘fully flush’ option, a circular flattened flange holds the optics firmly in place in the sensor housing. This design serves to protect the sensor as well as the goods on conveyor systems from being damaged. Different housing options allow for quick and easy mounting in a variety of applications. The PinPoint transmitter LED generates a precise, homogeneous and clearly visible light spot across the entire scanning range. It allows for easy detection of small parts and facilitates alignment. Clearly visible status LEDs provide the sensor’s operational status at a glance: on the plug end with the axial option and the sensor head in the case of the radial design.
