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. Keep the switch as close as possible to
the contact protection box, with a lead wire length of no more than 1
meter.
Contact Protection Box Connection
Hysteresis is the distance between the position at which piston movement
operates an auto switch to the position at which reverse movement turns
the switch off. This hysteresis is included in part of the operating range
(one side).
Note) Hysteresis may fluctuate due to the operating environment.
Please contact SMC if hysteresis causes an operational problem.

The above auto switches do not have internal contact protection circuits.
1. Operating load is an inductive load.
2. The length of wiring to the load is 5 m or more.
3. The load voltage is 100 or 200 VAC.
A contact protection box should be used in any of the above
conditions, Unless using a contact protection box, the contact life may
be shortened. (Due to permanent energizing conditions.)
D-A72(H) must be used with the contact protection box regardless
of load styles and lead wire length.

Please contact SMC when using built-in contact protection circuit style (D-
A34[A][C], D-A44[A][C], D-A54/A64, D-B54/B64, D-A59W, D-B59W) in the
following conditions: 1. The wiring length to load is more than 30 m; 2.
When using PLC with large flow current.

Solid state switch:
Manufactured upon receipt of
order as standard.
The standard lead wire length
of solid state switches with
timer, water resistant 2-color
indication type, wide range
detection type or heat
resistant 2-color indication
type is 3 meters in length.
(0.5 m is not available.)
Lead wire lengths of 3 m and
5 m are standard for magnetic
field resistant 2-color indicator
type solid state switches. (0.5
m is not available.)
Add “-61” at th end of the part
