## Description

This compact RM-EGB Series gripper from RobustMotion fits small collaborative robots (cobots) such as the [Dobot MG400](https://core-electronics.com.au/dobot-mg400-desktop-cobot-robotic-arm-pololu.html). It operates at 24 VDC, which can be supplied from the MG400, and the simple PNP-type PLC interface can connect directly to the MG400 I/O ports. A simple 3D-printed adapter (139k STEP) can be used to mount the gripper to the MG400 arm.

The gripper operates by sliding a pair of fingers together or apart laterally to grip and release. These fingers, which are designed to serve as mounting points for customized (e.g. 3D-printed) extensions, are able to exert consistent force in both directions, allowing them to grab parts internally (by opening into a gap) or externally (by clamping down) with missed pickup and dropped part detection.

The gripper can cover its full 6 mm stroke length in under 0.1 s, and in addition to the fully open and fully closed extremes, two preset intermediate positions (at 2 mm and 4 mm) are achievable with ±0.02 mm repeatability. The grip strength can be controlled by selecting from four preset force levels up to 60 N. See the [RM-EGB user’s manual](https://core-electronics.com.au/attachments/localcontent/RobustMotionRM-EGBgripperusermanual_15955713214.pdf) (2MB pdf) for more information.

The gripper has a 200 cm (80") cable with ten conductors terminating in a 12-pin, 2mm-pitch A2008H-12P connector. RobustMotion recommends cutting the connector off and using the individual wires. Note: pins 9 and 10 (DSW+/-) are not used on this version of the gripper.
