	• Maximum source current: 100 mA
	• Applied voltage: 30 V DC or less (between output and +V)
	• Residual voltage: 2 V or less (at 100 mA source current), 1 V or less (at 16 mA source current)
Utilization category	DC-12 or DC-13
Output operation	ON when all beam channels are received
	(OFF when one or more beam channels are interrupted)
Short-circuit protection	Incorporated
Response time	10 ms or less (12 ms or less when the interference prevention function is used)
Indicators Emitter	Emitting indicator: Green LED x 2 (light up during emission; one LED lights up for Frequency A setting, both LEDs light up for Frequency B setting)
	Job indicator: Red LED (lights up, blinks or lights off when the job indicator input is applied, selected by operation mode switch)
Indicators Receiver	Operation indicator: Red LED (lights up when one or more beam channels are interrupted)
	Stable incident beam indicator: Green LED (lights up when all beam channels are stably received)
	Job indicator: Red LED (lights up, blinks or lights off when the job indicator input is applied, selected by operation mode switch)
	* When an excess current flows through the output, the stable incident beam indicator and the operation indicator on the receiver blink simultaneously due to operation of the short-circuit protection circuit.
