We supply a wide range of exposed linear encoders from Heidenhain.

Linear encoders measure the position of linear axes without additional mechanical transfer elements. This eliminates a number of potential error sources:

• Positioning error due to thermal behaviour of the recirculating ball screw
• Reversal error
• Kinematic error through ball-screw pitch error

Linear encoders are therefore indispensable for machines that must fulfi ll high requirements for positioning accuracy and machining speed.

Sealed linear encoders are available with full-size scale housings for high resistance to vibration up to 30 m measuring length, as well as slimline scale housing for limited installation space up to 2040 mm measuring length.
