*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
Transmitter	+24 V, 0 V	22 AW G (0.32 mm)	0.3-A load: 47 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.
