Electric Gripper LEHR series

Product Feature

[Plug & Play]
Peripheral devices necessary for electric gripper drive are integrated as a unit. Only one electrical cable need to be connected for operation.

[Lineup]
We offer two types of lineup to accommodate a variety of workpieces and locations.

Basic type:
A type with a low height. The distance from the tip of the robot arm to the gripping point is short, so the moment on the arm is small.

Longitudinal type:
A type with a low thickness. Can be used in narrow spaces.

[Other]
・With internal battery-less absolute encoder
・Manual changer is standard equipment for easy tool change.

*1 Gripping force accuracy should be ±20% (F.S.).
Gripping with heavy attachment and fast pushing speed, may not reach the product specification.
In this case, decrease the weight and lower the pushing speed.
*2 Gripping speed should be set within the range during gripping operations.
Otherwise, it may cause a malfunction. The open/close speed and gripping speed are for both fingers.
The speed for one finger is half this value.
*3 There will be no influence of backlash during gripping operations.
Make the stroke longer for the amount of backlash when opening.
*4 A reference value for correcting errors in reciprocal operation which occur during positioning operations
*5 Impact resistance: No malfunction occurred when the gripper was tested with a drop tester in both an axial direction and a perpendicular direction to the lead screw. (The test was performed with the gripper in the initial state.)
Vibration resistance: No malfunction occurred in a test ranging between 45 to 2000 Hz. The test was performed in both an axial direction and a perpendicular direction to the lead screw. (The test was performed with the gripper in the initial state.)
*6 Indicates the max. power
