ASM POSIROT PMIS4/PMIR5 magnetic incremental encoder

The ASM POSIROT magnetic position sensor range has been expanded with the combination PMIS4/PMIR5, developed specifically for rotary applications. The advantages of this combination are high EMC protection, large guiding distance tolerance and a superior signal performance up to 327,680 pulses/360°.

The incremental, non-contact measuring system consists of the sensor head PMIS4 and an incremental magnetic ring PMIR5. The sensor head is made of a fully enclosed, shielded metal housing. It offers high protection against electromagnetic interference, thermal overload, and operating temperature range of -40 to +85°C and has a protection class of IP67.

The PMIR5 magnetic ring comes in three sizes with flange sizes of 83, 133 or 233 mm. They are available with decadic, binary or degree division and reach correspondingly 131,072 pulses/360°, 196,608 pulses/360° or 327,680 pulses/360°. Since the system operates magnetically, it is unaffected by contamination from oil and dust. For this reason it is suitable for use in harsh, dusty industrial environments.
