MOUNTING INfORMATION

Grippers Can be Mounted and Operated in Any Orientation

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-31

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.

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

PTFE impregnation.

The gripper’s main

components are made

of heat treated steel.

Inductive Sensor

Mounting Kit

Accessory (SD) in order to
sense jaw position. Comes

with 2 holders for tubular

sensors and 2 adjustable

flags (except size -12).

Magneto Resistive

Sensor Mounting Kit

The gripper comes with adjustable

slots for the 2 magnetic sensors

(to control jaw position)

Accessory (BR) in order to
adjust the opening of jaws,

the gripper to hold onto

Multiple

Air Ports

Side or top air

ports (top ports

require O-ring)

Adjustable Stop

between 0° to 180°

Shielded Plate and

Wiper Covers

Gripper body is shielded

to repel chips and other
particulate from internal

drive mechanism

Fail Safe Spring

Internal spring allows

part with loss of air

pressure

Mounting Patterns

DIRECTCONNECT™

mounting surface on back

of body (sizes 12-25)

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)

l The Fail Safe Spring Allow the Gripper

to Retain the Component Should the Air
Supply Fail or for the Gripper to be Used
in Single Acting Mode

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-RE, 180° Series pneumatic angular gripper
with spring assist, 20 mm (0.79") jaw opening and gripper force of 87 N (19 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,
each 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') length each. See accessory table below. CAD file available at omega.com.
