INTRODUCTION
1. INTRODUCTION
The MEGP 25E and MEGP 25LS grippers (Mecademic grippers) are electric parallel grippers developed
by Mecademic and Schunk, specifically for the Meca500 (R3) robot arm. The MEGP 25E (which replaces
MEGP 25) and MEGP 25LS use a removable connector cable.
Familiarity with the Meca500 robot and its user manual is required prior to installing and using
the grippers.
!
Improper installation of the grippers could seriously damage the Meca500 and the grippers
themselves. This grippers should therefore be used only by technical personnel who are familiar
with the Meca500.
1.1. Inside the box
Each of the two gripper models is supplied either individually or with the Meca500. In both cases, the
gripper is delivered in an anti-static bag containing the standard kit:
-1 MEGP 25E or 1 MEGP 25LS gripper;
-1 MGC-SS35 35-mm communication cable with straight connectors or
1 MGC-AA25 25-mm communication cable with 90° connectors;
-1 MEGP25-TAP adapter plate (made of unanodized aluminum) for attaching the gripper to the
Meca500’s mechanical interface (ange);
-4 M3X0.5 Torx at head screws of length 8 mm;
-2 M2.5X0.45 socket head screws of length 20 mm.
Note that Mecademic does not supply gripper ngers. These must be designed and machined
based on the workpiece that needs to be handled.
