OPTEX FA ST-400CN | Through-Beam Photoelectric Sensor | 4 m, NPN, Connector
The OPTEX FA ST-400CN is a through-beam photoelectric sensor with a sensing distance of 4 m, NPN output and a connector connection. Like the rest of the S Series, the ST-400CN is a small photoelectric sensor with a built-in amplifier in a 10 × 17.4 × 28 mm body, designed for high-speed production lines with a 0.5 ms response time. A BEF-W150-B mounting bracket is included with the ST-400CN.
