September 25, 2012 - ASM releases PMIS4/PMIR5 magnetic position sensors, 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 PMIS4/PMIR5 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 has protection class IP67.
Guiding distance is ± 1 mm. Available output types are HTL, TTL and TTL24V. 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 corresponding 131,072 pulses / 360°, 196,608 pulses / 360° or 327,680 pulses / 360°. Temperature range is -40°C to +85°C, the maximum pulse frequency is 480 kHz.
Since the system operates magnetically, it is unaffected by contamination from oil and dust. For this reason its suitable for use in harsh, dusty industrial environments.
