Comparison Table of PT Series Magnetic Encoder

The PT series is driven by magnetoelectric technology and has a unique interference shielding technology. There are multiple high-precision magnetic field sensors inside the encoder to measure the field strength changes of the rotor magnetic ring, which is formed by the precision calibration technology.

When installing the stator, can use an M1.6 screw to pass through the M2 threaded hole or can use an M2 thread with an M2 screw to lock it.

When installing the rotor use a special tool to tighten it

24M - 24-bit single turn + normal multi turn

Multi-turn clear after power failure Multi-turn only valid when power on

24BM - 24-bit single turn + battery multi turn

After power failure, it can still maintain multi-turn measurement by using battery power

24FM - 24-bit single turn + flash multi turn

Only ±90° rotation is allowed after power failure No battery required

The SSI protocol does not have CRC check. It is recommended to use BISS-C with the same hardware to improve reliability.

When the Tamagawa protocol selects 17 bits, the output parameters are 17M-T, 17BM-T, and 17FM-T.When 23 bits are selected, the output parameters are 23M-T, 23BM-T, and 23FM-T.
