OPTEX FA SD-20N | Diffuse-Reflective Photoelectric Sensor | 200 mm, NPN, Cable
SD-20N is an OPTEX FA diffuse-reflective photoelectric sensor offering a sensing distance of 200 mm, NPN output and a cable connection. The S Series that the SD-20N belongs to pairs a compact 10 × 17.4 × 28 mm housing with shock resistance of approx. 100 G, so it can be fitted where workpieces may knock the sensor. A BEF-W150-B mounting bracket is included with the SD-20N.
