m&h Laser Tool Setter LTS35.65-23

m&h LTS35.65-23 - the compact Laser Tool Setter

The laser tool setter Compact is designed for usage in machines with a limited amount of space for the measurement of particularly small tools.

With a length of 123 mm and a height of only 66 mm, there is space for the system even in a small machine. The cable outlet is also only downward to prevent the need for more space for cables and the pneumatic supply.
