Output		NPN open-collector transistor ・Maximum sink current: 100 mA ・Applied voltage: 30 V DC or less (between output and 0 V) ・Residual voltage: 1.6 V or less (at 100 mA sink current)
	Output operation	ON when all beam channels are received / OFF when one or more beam channels are interrupted (OFF, also, when the sensor fails.)
	Short-circuit protection	Incorporated
Response time		12 ms or less
Indicators	Emitter	Emitting indicator: Green LED (lights up under normal emission, blinks under emitting circuit failure or on cable break between the synchronization and the external input terminals when interference prevention function is used (only the emitting indicator of the Sensor B blinks), and lights off under no emission)
Indicators	Receiver	Operation indicator: Red LED (lights up when one or more beam channels are interrupted, and blinks when extraneous light is received) Stable incident beam indicator: Green LED (lights up when all beam channels are received stably) Unstable incident beam indicator: Yellow LED (lights up when one or more beam channels are received unstably) * The three color indicators blink in rotation when the receiving circuit fails, and blink simultaneously when the output circuit fails. The operation indicator and the unstable incident beam indicator blink alternately when the synchronization wire breaks or the emitting circuit fails.
