Servo-Electric Grippers include position feedback.

Press Release Summary:

Two-finger parallel gripper, Model EGN 100 and 3-finger centric gripper, Model EZN 64 feature integrated servomotor and encoder for position feedback and can be actuated in force or positioning mode. EGN 100 offers stroke range up to 20 mm and grip force of 600 N, while EZN 64 offers 12 mm stroke and grip force of 500 N. Supplied with 24 Vdc, external controller includes digital input and operates with CAN-bus or RS-485 communication interface.

New 2-Finger and 3-Finger Servo-Electric Grippers

SCHUNK Inc. introduces a new series of servo-electric grippers, EGN 100, a 2-finger parallel type and EZN 64 of the 3-finger centric type. The basic principle of these two servo grippers comes from their proven pneumatic counterparts PGN+100 and PZN+64. Due to the integrated servomotor and encoder for position feedback, the grippers can be actuated in either a force or positioning mode and allows for adjustment of the gripping force, position or speed.

The EGN & EZN have an external controller that is supplied with 24V DC and can be controlled by a CAN-bus or RS 485 communication interface. This controller also has a digital control input making it easy to integrate it to an existing application without the CAN-bus or RS 485 communication capability capabilities. The EGN 100 gives a stroke range of up to 20mm and a grip force of up to 600 N (135 lbf). The EZN 64 has a stroke of up to 12mm and a grip force of 500 N (112 lbf).

With the capabilities of the EGN & EZN servo grippers you can improve a wide range of processes. The position feedback of the encoder allows you to sort parts while transporting them instead of having a separate measuring operation determining the part size. Typically on robotic applications, the end effector is the only component that requires a pneumatic supply and valve to actuate it. The EGN or EZN will eliminate the need for air in these applications. The EGN & EZN is a great addition to the growing electric product offering of SCHUNK.
