Oilproof heavy-duty vinyl cable: o4, 0.3 mm2 x 2 cores (Brown, Blue), 0.5 m Note 1) Refer to page 58 for reed switch common specifications. Note 2) Refer to page 58 for lead wire lengths. Note 3) Under 5 mA, the strength of the indicator light is poor. In some cases, visibility of the indicator light will not be possible where the output signal is less than 2.5 mA. However, there is no problem in terms of contact output, when an output signal exceeds 1 mA or more. Operating position .......... Red LED illuminates. Optimum operating position ..........
