B18320 Electric Clamps - Parallel drive

Version
This electric clamp is an electrically operated swing clamp.

Description
The electric clamp is driven by a wear-resistant brushless DC motor. The motor speed is transformed by means of a gear and a threaded spindle into the swing and stroke movement of the piston rod. For swinging the clamping arm by 180°, an axial stroke of only 3 mm is required.
If the clamping arm collides during the swing motion with a workpiece, the mechanism is protected against overload.
The direct current motor is automatically and immediately switched off. When unclamping, the clamping arm always swings back to the off-position.

Integrated control
The electronic control for the DC motor is on a board in the housing of the electric clamp.

Electric connection
Power supply and signal exchange for external control are transmitted by two short cables with plug-type connector. Cable sockets are available for the customer's connection (see connection accessories).

Safe touch voltage
The used DC voltage 24 V is considered to be a "low voltage" and thus it is not dangerous for people in case of contact.

Power supply
For motor and electronic control a DC voltage of 24 V with a residual ripple of max. 10 % is required.
For the DC motor, we recommend the use of a switching power supply with a current output of 15 A per connected electric clamp. When operating several clamps at the same time, the line is to be enlarged correspondingly.
The electronic control has to be supplied by a separate power supply (24 V DC / 100 mA).
