Orientalmotor EH Series Electric Grippers
Made in Japan
Manufacturer: ORIENTAL MOTOR CO., LTD.
Model: EH Series
Key Features
A “Delicate Grip” Approach to a Wide Variety of Load
The operating current can be set in 1 % increments, allows fine-tuning the gripping force.
Grasp
Easy-to-damage and easy-to-deform loads can be gripped.
The 3-finger type is suitable for gripping spherical, cylindrical or easily deformable loads.
Align
Loads can be oriented and aligned.
Measure
Load size can be determined and measured.
For Delicate Operations, the EH Series is Recommended Over a Pneumatic Gripper
Adjust the Gripping Force in 1 % Increments (2-Finger and 3-Finger)
Adjustment with a pneumatic gripper’s regulator (pressure reducing valve) is unnecessary. The gripping force can be easily and finely adjusted with digital settings.
Adjust the Speed in 0.02 mm/s Increments (2-Finger)
Adjustment with a pneumatic gripper’s speed controller (speed control valve) is unnecessary.
Adjust the Traveling Amount in 0.02 mm Increments (2-Finger)
This gripper takes advantage of the high positioning accuracy of the stepper motor.
Position Monitoring With an ABZO Sensor (2-Finger and 3-Finger)
Detailed position information can be monitored. When using the 2-finger type, position information can also be used to determine the load size.
2-Finger Type and 3-Finger Type Can be Used for Different Applications

Features of 3-Finger Type
Due to the large permissible axial load, it is suitable for application with large load masses.
Each finger opens and closes while rotating.
Advantages of AZ Series Equipped
Battery-Free Absolute Encoder Equipped
It is equipped with a small battery-free mechanical absolute encoder (ABZO sensor). This can help improve productivity and reduce costs.
- Mechanical-Type Sensor
Retains positioning information even when power is not supplied - Multi-Rotation Absolute Encoder
Absolute position detection is possible with ±900 (1,800) revolutions of the motor shaft from the home position
No External Sensors Required
As it is an absolute system, home sensors or limit sensors are not required.
Advantages
- Improved High-Speed Return-to-Home + Return-to-Home Accuracy
- Reduced Cost
- Simple Wiring
- Not Affected by External Sensor Malfunction
Battery-Free
Mechanical sensors do not require batteries.
Positioning information is managed mechanically by the ABZO Sensor.
Advantages
- No need to replace batteries
- Unlimited Driver Installation Possibilities
- Safe for Overseas Shipping
Simplifying the Main Program via Sequence Function
The AZ Series come equipped with a wide variety of sequence functions such as timer settings for linked operation and during operations, conditional branching, and loop operation. (excluding some models)
It can be set up using the support software MEXE02, which simplifies the sequence program of the host system.
- Positioning Operation Data Setting Value (max. 256)
- General-Purpose I/O Signal Counts (Input 10, Output 6)
- Communication I/O Signal Counts (Input 16, Output 16)
AZ Series-Equipped Product Line
Since the motors installed are the same, the operating and maintenance methods are the same.
