• Digital readout for universal use on lathes, drilling, milling and grinding machines

• High-precision system for retrofitting your machine tool

• Different sizes to ensure a quick and easy installation, even in restrict spaces, especially with the mounting brackets supplied





Te c h n i c a l s p e c i f i c a t i o n s• Sturdy completely metal housing• Connected value 80 to 260 V, 50-60 Hz• Power consumption 25VA• Working temperature 0 to 45 degree• Signal processing = EIA-422A linedriver (better signal transfer than TTL)• Maximum input frequency 5 MHz

S c a l e sStandard scales: KA-300 · KA-600

Glass scales in small constructionfor small machines and tight spaces:KA-500 · KA-200

Scales in excess length longer than 3.000 to 100.000 mm:KA-800MThe scale consists of three different parts. An initial part with 1200 mm, then all following middle parts with 1200 mm and the endpiece in 400, 600, 800, 1000 and 1200 mm. If necessary, the endpiece can be ordered to the exact millimeter. Please note when ordering, you always need 100 mm more than the travel length. Resolution 5 μm and 1 μm.

4 Completely calculator function4 Angular and bow function (Interior and exterior machining of

roundings)4 200 memory positions4 Tool diameter compensation4 Switching mm/inch4 Choice of coordinates abs./inc.4 Linear rows of holes4 Bolt circle processing4 Pocket milling function4 Special digital filter function when used for grinding machines (prevents

a possible flickering of the last number, which sometimes can occur due to the natural frequency of a grinding machine)

4 With memory function. If the display is completely switched off or has a power failure, the last displayed value is saved and displayed again after switching on

4 With “snooze function”, this means when travel is on by mistake when machine is off, this values will be saved

4 Middle determination by halving the values4 Doubling the values for diameter display in lathe mode4 Cone calculation in lathe mode4 “Real” third display segment in lathe mode. The first segment shows X,

the second segment Z and Zo to be cleared together (or Z alone) and the third segment Zo alone

4 Optional linear error compensation option4 Furthermore the display has a non-linear-40-points error compensa-

tion (this is a “real” correction and not just approximate as in linear error compensation)

4 Optional RS232 interface
