1. Use cable whose O.D. is within the size in

the figure to maintain water resistant

performance.

2. After wiring, confirm that tightening gland

and all screws are tightened.

∗ Refer to the applicable internal circuit diagram (numbers q to u) on page 1587.

Note 1) Refer to page 1584 for reed auto switch common specifications.

Note 2) 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.

Note 3) The auto switches can operate at 12 VDC, but consider the internal voltage drop of the auto

switch described in Reed Auto Switch Precautions on page 12.
