POSITAL 22 mm Multiturn Kit Encoders

POSITAL introduces its 22 mm (0.87 in.)  multiturn kit encoders designed for use with small-diameter motors.

• High-precision multiturn absolute position feedback device
• Provides full multiturn measurement capabilities without need for backup batteries
• Rotation counter system is entirely self-powered to keep counter circuits operational in the event of a power failure or control system outage, maintaining full record of any rotations that the motor drive shaft experiences
• Motor’s complete rotary position, including rotation count, is forwarded to central controller once power is restored
• Eliminates need to return the machine to a known reference state and re-start rotation counts, typical of systems with incremental encoders, improving process security, efficiency, and operating costs
• Compactly designed, measuring just 23 mm (0.91 in.) high
• Easy to integrate into existing motor designs, with straightforward installation and calibration procedures
• Assembly can take place under normal factory conditions, with no need for clean room environments
• Vendor-neutral SSI and BiSS C communication interfaces are supported
• Integrated calibration function simplifies setup: with a few turns of the shaft, kit unit automatically adjusts itself to any minor misalignment between motor and sensors and stores correction parameters in its memory  
• Offers 17-bit resolution and an accuracy of 0.09 degrees
• Reduces installation space requirements by almost two thirds compared to 36 mm (1.41 in.) series due to repositioning of key components
• Features Wiegand sensor which responds to a rotating magnetic field, generating voltage pulses with every rotation

The compact design of the multiturn kit encoder aids use in miniature motors and drives.POSITAL
