*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.
