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.

Fig.: Electronic Components

The 3-finger type is suitable for gripping spherical, cylindrical or easily deformable loads.

EH Series 3-Finger Gripping a Spherical Load

Align

Loads can be oriented and aligned.

EH Series 3-Finger Gripping a Cylindrical Load

Measure

Load size can be determined and measured.

Fig.: 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.

ABZO sensor
  • 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.
