Incremental Position Measurement System
Magnetic incremental feedback: analog or digital, ±1 µm repeatability, ±8 µm/m accuracy
±1 µm repeatability ±8 µm/m accuracy Oil / dust / water
Electrical Components
Also listed as Position Measurement System
Two magnetic encoder series — incremental PM and absolute APM — built on a German magnetizing process. Analog or digital incremental output, true-absolute BiSS or H-code with no backup battery, and the fixtures that keep the scale parallel to the head.

Why HIWIN
PM Series types C, PG (20 to 55), and T output analog or digital at ±1 µm repeatability and ±8 µm/m accuracy, sealed against oil, dust, and water.
APM Series encodes position on the scale. No buffer battery, no homing move, IP68, BiSS 27-bit or H-code into the drive.
Chips, splash, and oil that blind an optical scale leave a magnetic track readable. The head never touches the tape.
C type and PG20 to PG55 put the sensor on a HIWIN guideway so the encoder does not need its own bracket or footprint.
