Short-circuit protection : Incorporated
Indicators
Emitting indicator: Green LED × 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)
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.
Response time : 10 ms or less (12 ms or less when the interference prevention function is used)

Sensing object : ø30 mm ø1.181 in or more opaque object (completely beam interrupted objects)
Supply voltage : 12 to 24 V DC ±10 % Ripple P-P 10 % or less
Interference prevention function : Incorporated
Test input (emission halt) function : Incorporated
Environmental resistance
Pollution degree : 3 (Industrial environment)
