Detects an object within the convergent area is also available Cumbersome soldering is not required. It saves space and improves reliability. -LH -LH With connector 0 mm.99 in Hardly affected by background Even a specular background does not affect the sensing performance if the sensor is located 30 mm.8 in away from it. 30 mm.8 in However, the specular background should be a plane surface, directly facing the sensor. A spherical or curved background may be detected. Dark object detectable Since the sensor is very sensitive, it can detect even a dark object of low reflectivity. Minute object detectable A ø0.0 mm ø0.00 in copper wire can be detected at a distance of mm 0.9 in under the optimum condition. Optimum setting distance is mm 0.9 in mm 0.9 in Sensing object Background ø0.0 mm ø0.00 in copper wire CH - 3 Busslingen mm 0.98 in

4 Micro Photoelectric SERIES USE MEASURE- MENT STATIC CONTROL HUMAN ENERGY CONSUMPTION FA VISION PRECAUTIONS FOR PROPER USE type Cautions in plugging or unplugging a connector Do not plug or unplug a connector more than times. Be sure not to give stress more than N to a terminal of both a connector and a sensor. If you do not follow the above cautions, it will cause a poor contact. Procedures of plugging or unplugging a connector Insert a connector straight into a sensor until the connector lug is locked by the sensor hook. When unplugging, give as much stress as a connector lug can be relieved from a hook. Then unplug it. Caution: Be sure to hold a connector when plugging or unplugging it. Do not hold a terminal or a cable when plugging or unplugging the connector. Otherwise, it will cause a poor contact.
