SICK HTB1B-P4828ED02 1077092 Photoelectric Sensor

The SICK HTB18-P4B2BED02 (1077092) Sure Sense photoelectric sensor delivers reliable, background-suppressed detection in an compact M18 housing with a blue body, optimized for conveyors and packaging lines. It operates with visible red light at 631 nm (PinPoint LED) and a background-suppression principle that helps distinguish targets from cluttered backgrounds, up to a maximum sensing distance of 300 mm and a preset distance of 50 mm. The device measures 16.2 x 45.5 x 31.8 mm and enables head/side mounting on an M18 base (24.1–25.4 mm), with a right-side potentiometer for light/dark switching and range adjustment. Connectivity is via a 4-pin M12 connector, and the output is PNP with a supply tolerance up to 30 V DC, aligning with common industrial controllers. This sensor is well-suited to presence and part-detection tasks on production lines where background signals could otherwise cause false triggers, such as object detection on assemblies, packaging, or automated sorting applications, providing precise, repeatable results in challenging industrial environments.
