Scik sensor GSE6-P1112 1052452 principle of opposite beam

It belongs to a pair of photoelectric sensors, with the transmitter and receiver installed separately. The transmitter emits visible red light (wavelength 650nm), which is received by the receiver. When an object blocks the light beam, the receiver detects a change in light intensity, thereby changing the output state. It features PinPoint LED light source technology, with bright and precise light points that are easy to align. Adopting SICK ASIC chip, it is resistant to environmental light interference and inter sensor interference. There is also a large knob for easy adjustment, and the indicator light is bright.
SICK GSE6-P1112 (order number 1052452) is a compact square sensor based on the through beam photoelectric detection principle, belonging to the G6 series. The core principle is to achieve high reliability object detection by detecting whether the light beam is obstructed.

1、 Detailed explanation of the working principle of the shooting type
A reflective photoelectric sensor consists of physically separated emitters and receivers. GSE6-P1112 is usually used as a receiver unit and needs to be paired with a matching transmitter (such as GSE6-E1112).
Beam emission: The emitter integrates a PinPoint LED light source internally, emitting visible red light with a wavelength of 650nm. This "laser like" technology makes the light spot brighter and more precise, and can maintain a small spot diameter at a distance (such as about 375 millimeters at 12 meters), greatly facilitating installation alignment.
Beam reception: The receiver continuously receives light signals from the transmitter in the opposite direction.
Status judgment and output:
When there is no object: the beam is unobstructed, the receiver receives sufficient light signal, and the internal circuit maintains an output state (such as PNP output high level).
When there is an object blocking: When the object being measured enters the optical path, the beam is partially blocked, and the intensity of light detected by the receiver undergoes a sudden change.
Signal switching: The SICK dedicated ASIC chip inside the receiver quickly processes this change and immediately changes the state of its PNP switch output (such as to low level), while the large and bright LED indicator light on the housing will light up, providing intuitive status indication.
Mode selection: This sensor supports the switching function between Light ON and Dark ON, and users can set the logic of "triggered when there is light" or "triggered when there is light blocking" according to their needs.
