The operated load is an induction load.
The length of wiring to the load is 5 m or more.
The load voltage is 100 VAC.
A contact protection box should be used in any of the above situations.

The hysteresis is the difference between the position of the auto switch as
it turns “on” and as it turns “off”. A part of operating range (one side)
includes this hysteresis.
Note) Hysteresis may fluctuate due to the operating environment.
Please contact SMC if hysteresis causes an operational problem.
Auto Switch Hysteresis
Note 1) Lead wire length “Z” (5 m applicable auto switches) is as follows.
Reed auto switch: Not available
Solid state switch: All types are produced upon receipt of order.
Note 2) For solid state switches with flexible wire specification, add “–61” at the
end of the lead wire length.
∗
Oil resistant flexible heavy-duty cord is used for D-M9
as standard. No need
to suffix -61 to the end of part number.

To connect a switch unit to a contact protection box, connect the lead wire
from the side of the contact protection box marked SWITCH to the lead
wire coming out of the switch unit. The switch unit should be kept as close
as possible to the contact protection box with a lead wire that is no more
than 1 meter in length.
