Designed for applications on standard machines with travels up to 520 mm.
With reference marks every 50 mm and detachable cable connector built into the reader head (except the MMK series where the reader head comes standard with a 3-meter attached cable). With very small profile, 5 mm less than the M series they are ideal for tight spaces.
Measuring lengths in millimeters:
