Digital output signals
Square wave differential line driver to EIA RS422
* On readhead with 1 m cable; for longer cables please consider
Reference mark
The repeatable bi-directional reference signal can be provided in 3 ways.
1) Stick-on reference mark. The LM13 readhead should be ordered with the reference mark option. After installation
2) Selected at point of order. The LM13 readhead should be ordered with the reference mark option. If required the
3) Every 2 mm. The LM13 readhead should be ordered with this specific mode activated only.

NOTE: The shape of the cut and position is critical so
of the scale a reference mark sticker can be applied to the scale at the required position using the reference mark
applicator tool. Ensure that the reference sticker is oriented to the corresponding side of the readhead that has the
reference mark designator marked.
cover foil can be installed over the cut reference mark.
this option is only available as factory order.
