Angular Gripper

EHVE Series

EHVE Series

Angular Gripper◆Long LifeLong life realized thanks to the use ofchrome molybdenum steel for the levers
and hardening of the main parts.

◆Adjustable Switch Position

2 switches are mountable so you cancheck opening and closing of the levers.
The switch is compact so it does not
protrude from the main body side.

◆Mounting Available from 3 Directions

You can select the mounting direction freely
because 3 faces have a mounting screw.

◆Mounting Adapter is optional

Mounting variation has been further
expanded by providing a gripper mounting adapter for each size.

EHVE Series■Speciﬁcations

Note 1): L indicates the distance (cm) from the fulcrum pin to the grip point. (The levers are retained in the horizontal condition.)
This is an eﬀective value when the pressure is 0.5 MPa and L = 30mm. However, when the L = 25mm only for EHVE-8.
Note 2): The outside dimensions indicate the main body dimensions. (Excluding the levers)323

1. Opening/Closing Stroke Diﬀerence(Opening/Closing Angle Diﬀerence)
The distance from the position where the one side levermoves and the switch turns on from the position where thelever moves in the reverse direction and the switch turns
oﬀ is called "response diﬀerence".
Variation of the switch ON/OFF position when the one side
lever is moved in a certain direction.
