Galvanically isolated drives
Back
Before

Our specially developed, backlash-free, and galvanically isolated drives can be used with insulated sockets and bits via an integrated quick-change chuck. They are particularly suitable for hand-guided screwdriving with position monitoring and are primarily used in battery assembly. The backlash-free drive ensures that even very closely spaced screw locations can be reliably distinguished with long bits in accordance with the zero-defect strategy. The galvanic isolation and insulated jacket surface minimize the risk of contact with live components, prevent dangerous short circuits due to high electrical currents, and protect battery modules from accidental short-circuiting.

Structure

In the insulating core, the electrical conductivity between the screw and the tool is completely interrupted, enabling galvanic isolation in the axial direction.
A freely rotating outer sleeve provides radial insulation
and offers an isolated and galvanically isolated assembly solution.

1. Electrically isolated connection

2. Insulated plastic jacket surface

Product advantages

System design & flexibility

Depending on the variant, commercially available 1/4″ or 7/16″ (DIN 3126 E) bits can be attached

Performance & ergonomics

Narrow screw locations distinguishable by position detection
Absorption of radial loads and tilting moments

Process integration & operational safety

Protection of workers and hand screwdrivers or built-in spindles from electrical voltage

When the sleeve is touched by the worker’s hand or collides with the component, the sleeve stops. Injury to the hand or damage to the component is thus ruled out.

Technical properties

Tested in all applicable areas of the DIN EN 50178:1998-04 and DIN EN 62477-1:2017-10 standards

Electrical isolation between drive and output shaft
Jacket surfaces on the straight drive are electrically insulated
Both outer sleeves are mechanically decoupled from the basic tool
Attachment by plastic protective housing on the hand screwdriver or on the built-in spindle
The ball-bearing drive shaft guarantees very high concentricity on the output shaft without radial play

Area of application

Screwdriving applications in the high-voltage range
Hand-guided or hand-held screwdriving with or without position monitoring

With position-monitored screwdriving using a JÄGER Handling, the following screw distances can be achieved depending on the product.
