LEGS Linear Twin LTC40


The twin concept is designed for high force output in a compact body, in this case a stall force of 40N. This gives a more robust design without the need of ball bearings.

It has direct drive with no backlash and can microstep in the sub-nano millimeter range.

The LTC40 version is similar to the LT40 but is covered and has a stroke of maximum 12.8mm. Does not come with built-in encoder but with a range of adapter solutions.

Full force power-off locking is a safety function inherent to the design. Not designed for vacuum and non-magnetic environments.

For order information see motor nomenclature as picture above.
