Retroreflective Mode Miniature High Performance MHP Sensors
MHP Series miniature photoelectric sensors
MHP series photoelectric retroreflective mode sensors
Our MHP series photoelectric sensors include retroreflective mode sensors. There are visible red and infrared LED light sources available. The MHP family has a rugged IP69K housing, which can withstand harsh environments and high-pressure wash down areas. Polarized and non-polarized models are available. The polarized models are able to effectively detect shiny objects. Options available are cable or quick-disconnect models and AC or DC models. The sensing ranges are 2.4 m and 9.1 m. Outputs available are NPN and PNP or thyristor.
Retroreflective mode sensors establish a light path between the sensor and a special reflector. An object is detected when the light path is broken. Typical retroreflective sensors provide a longer sensing range than a diffuse mode sensor. In some models a visible red LED is used to aid in the installation and alignment of the reflector. A polarizing filter is used to eliminate false signals that may occur if a shiny target passes in front of the sensor. Many types of reflectors are available.
