Gripper is located from the
top with 2 dowel pins and
assembled with 2 screws.
Fingers are centered over the
jaws, located with 1 dowel pin
and assembled with 2 screws.
C-25
DIRECTCONNECT mounting pattern:
Gripper is located with 2 dowel
pins and assembled with 4 screws.
Alternative pattern: Gripper is
located with 2 dowel pins and
assembled with 2 screws.
The gripper
is protected
from falling
debris when
it is mounted
and operated
upside down.
Gripper can be
operated utilizing top
manifold air ports.
PRODUCT fEATURES
Gripper Attachment
Gripper mounting from
side or bottom
FKM Seals
FKM seals for high temperatures
-30 to 150°C (-20 to 300°F) are optional
Quality Components
Made from aluminum
alloy anodized with

components are made
of heat treated steel.
Inductive Sensor
Accessory (SD) in order to
sense jaw position. Comes
with 2 holders for tubular
sensors and 2 adjustable
flags (except size -12).
Mounting Kit
Magneto Resistive
Sensor Mounting Kit
Standard mounting slots
for magneto resistive sensors.
(sensors sold separately)
Adjustable Stop
Accessory (BR) in order to
adjust the opening of jaws,
between 0° to 180°
Shielded Plate and

OPERATING PRINCIPLE
l A Double Acting Piston, with a Ring
Magnet for Magneto Resistive Sensing,
is Connected to a Fork Driver on which
2 Drive Pins are Fixed
l Jaw Rotation is Synchronized with the
Drive Pin-Jaw Assembly
l Sliding in These Slots, Drive Pins Convert
Vertical Motion of the Piston into Rotating
Opposite Synchronous Motion of Both Jaws
l Each Jaw Has a Useful Rotation Stroke of
90°, Between the 90° Open Position and
the 0° Gripping Position, Plus a Gripping
Over-Stroke of Approximately 1.5° Before
Reaching the Fully Gripped Position; Jaws
Have to be Designed for a 0° Gripping
Position (Parallel Jaws)

Jaws have to be designed for a 0° gripping position
(parallel jaws).
Jaws will close 1.5° past parallel. To limit shocks at
the end of an opening or closing stroke, it is highly
recommended to design jaws with minimal inertia
(as light and short as possible).
Flow Controls make it possible to reduce the rotation
speed and are highly recommended.

Ordering Example: DCT-12M, 180° Series pneumatic angular gripper with 18 mm (0.71") jaw opening and gripper force of 32 N (7.2 lb). See
air fittings for M5 threaded flow control valve, highly recommended due to jaw closing 1.5° past parallel. Suggested accessories include two
PNP magneto resistive sensors with short 90° barrel OHSP-011, and BR-CT-16, adjustable stop kit.
Quick disconnect sensors will require cable, CABL-013, with 5 m (16') length. See accessory table below. DCT-16M, 180° Series pneumatic
angular gripper with 20 mm (0.79") jaw opening and gripper force of 70 N (16 lb). See air fittings for M5 threaded flow control valve, highly
recommended due to jaw closing 1.5° past parallel. Suggested accessories include two PNP inductive quick disconnect sensors, OISP-014,
with two mounting kits, SD-CT-16 and BR-CT-16, adjustable stop kit. Quick disconnect sensors will require cable, CABL-013, with 5 m (16')
