*1. Use of the Spatter Protection Cover causes a 10% maximum sensing distance attenuation.
*2. The consumption current must not exceed 1.35 A for both the control outputs and auxiliary output. The rated current
       is the sum of the Transmitter (285 mA), Receiver (450 mA), control output 1 (625 mA), control output 2 (625 mA),
       and auxiliary output (100 mA).
*3. The 24-VDC value is a nominal value. The actual voltage depends on the supply voltage. Actual voltage = Supply
       voltage − 1 V.

Cable Extension Length

The maximum length and wire gauge for input and output signals are given in the following table.

Type Signal name Wire gauge Rated maximum length
Receiver Control outputs 1 and 2 22 AW G (0.32 mm) 300-mA load: 45 m, 625-mA load: 22 m
Auxiliary output 22 AW G (0.32 mm) 50 m
Start input 24 AW G (0.20 mm) 50 m
External device monitoring (EDM) input 24 AW G (0.20 mm) 50 m
+24 V, 0 V 20 AW G (0.52 mm) 1.8-A load: 12.5 m, 1-A load: 22 m

Note: Keep the cable length within the rated length. Failure to do so is dangerous because it may prevent safety functions
           from operating normally.
