WHEN USING LS SERIES LIMIT SWITCHES
The operating head can be set to four positions. To set to the
desired position, remove the four head tightening screws and rotate
the head 90˚ to one of the four different positions. When changing
the direction of the operating head, change the direction of the
internal plunger at the same time (excluding
1LS-J500, 1LS-J550
and
1LS-J50). The roller plunger can be set to one of two different
positions 90˚ apart.
1.
Changing the position of the operating head
The operation direction can be set to three sequences (excluding
1LS-J500
, 1LS-J550 and 1LS-J50). Lever type limit switches can
be set to operate electrically when moved either clockwise or
counterclockwise by changing the direction of the internal stepped
plunger.
2.
Changing the operating direction of roller lever type
3.
Indicating the operation set position on the roller lever type
The indentation on the roller plunger is for preventing excessive or
insufficient plunger operation. Determine the position of the
actuating element so that the indentation on the plunger fits into the
top surface of the bushing.
Excessive or insufficient pushing of the lever can be eliminated to
ensure stable prolonged use by setting so that the pointer that
rotates with the lever enters the head's protrusion zone. The
position of the protrusion zone varies with different model types,
such as standard , high sensitivity, and 90˚ T.T. types.

If the screw of the mating part is made of resin, the threads can
easily be damaged when the connector is first tightened. When
assembling the connector, align the center of the cores, push in as
far as possible, and then turn to tighten.
Be sure to tighten fully by hand. The recommended tightening
torque is 0.4 to 0.6 N
·
m. Use of a tightening tool may damage the
connector. If the connector is not tightened firmly, IP67 protection
may be lost, or the connector may come loose.
Roller lever type
For roller lever type switches, we recommend setting the distance from
the switch mounting hole to the actuating element as shown below.

Before inserting or removing connectors, be sure to the turn the
power OFF. When removing, hold the connector itself--do not pull
by the cable.
