LOCKING MECHANISM & MANUAL OPENING
The Series PLK incorporates a locking mechanism that keeps
the pin retracted and the fi nger extended so panels are trapped
in position on the pin. The locking mechanism does not maintain
clamp force when pressure is lost. During normal operation, air
pressure moves the piston, releasing the lock, allowing the pin to
extend, the fi nger to retract, and unclamp the part. To manually
unlock the clamp, fi rst remove air pressure, then loosen the screw

and rotate the cover out of the way. Insert a small screwdriver under
the dowel pin and lift it up. This will release the lock, extend the
pin, and retract the fi nger. (See diagram.) The R01 or R02 option
can also manually unlock the clamp. First, remove air pressure then
push the rod into the cylinder, moving the piston. This will release
the lock, extend the pin, and retract the fi nger. (See diagram.)

Provides the clamp with the adjustable lock already set for
the maximum material thickness for the application. Specify the
thickest material including tolerances and add .02 inches [.5 mm] for
clearance.
Example: 1 mm material with a tolerance of ± 0.1 mm plus
0.5 mm clearance = 1.6 mm
Specify MT16 and the clamp will arrive preset to lock at that
material thickness. The sequenced design prevents the fi nger from
retracting until the pin is fully extended. The part can move the
amount of clearance between the lock bracket and adjustment screw,
but the extended fi nger keeps the part trapped securely on the pin.

This option provides clamp and unclamp sensing by affi xing
an aluminum housing to the side of the clamp body. The unclamp
switch is fi xed needing no adjustment. The clamp switch is
adjustable throughout the entire clamp stroke. Loosening the M5
screw and sliding it up or down adjusts the clamp switch position.
PS positions the S02 switch to sense unclamped and the S01 switch
to sense clamped. PR positions the S01 switch to sense unclamped
and the S02 switch to sense clamped. See diagrams for satellite
switch to quick disconnect pin number relationships.

R01 SENSOR FLAG
R02 DOUBLE ROD
OPTIONS & KITS: SERIES PLK CLAMPS
Provides an external fl ag on a piston rod that extends out of the
bottom of the clamp.
The position of the fl ag indicates if the pin is extended or
retracted. Flag travel varies with the panel thickness, 1 mm min. to
10 mm max. The white composite fl ag can be seen by optical sensing
systems. Manually pushing the fl ag toward the clamp body will
overcome the internal locking feature.
Provides manual unlocking ability from below the clamp.
Manually pushing the external rod that extends out the bottom will
overcome the internal lock.

LOCK ADJUSTMENT PROCEDURE: SERIES PLK CLAMPS
1) Loosen and remove the four socket head cap screws (see
exploded view item no. 10).
2) Lift the part support and rotate it 180° until the wrench hole is
over the lock adjustment screw.
3) Replace the two screws to hold the part support in place during
lock setup. Back the adjustment screw out until it touches the
bottom of the part support.
4) Now, determine the thickest material the lock needs to hold.
Add the material thickness, its tolerance, and add .02 inches
[.5 mm] for clearance.
Example:
1 mm material with a tolerance of ± .1 mm + .5 mm clearance
= 1.6 mm setup dimension
5) Place a 1.6 mm setup part (or feeler gage) under the fi nger and
close clamp with pressure.
SHIM SHIM SHIM
1/2 TURN
DETAIL A DETAIL B DETAIL C
6) With the fi nger clamping the 1.6 mm setup part, turn the lock
screw in gently until you feel it touch the top of the lock lever.
Once it touches, back it off 1/2 turn.
7) Drop air pressure on the clamp and try to pull the pin and
fi nger up with the setup part. The pin should move very little
and the fi nger will stay extended. (The PLK’s sequenced
design prevents the fi nger from retracting until the pin is fully
extended. The part can move the amount of clearance between
the lock bracket and adjustment screw, but the extended fi nger
keeps the part trapped securely on the pin.)
8) Now, extend the pin with pressure or the manual opener.
Remove the two screws holding the part support in place.
Lift and rotate it 180° to hide the lock adjustment screw and
retighten the four screws to 46 in-lb [5.2 Nm]. The lock is set.
