Description

A non-contact high performance off-axis absolute rotary encoder designed for integration into space-constrained applications. Hollow ring, true absolute functionality, high speed operation and high degree of IP protection make this encoder suitable for many applications.
The magnetic encoder system consists of an axially magnetized ring and a read-head.
The encoders come in CAN, SSI,SPI, I2C, PWM, asynchronous serial RS422/RS485 and analogue current or voltage output variants and offer a range of binary resolutions to 12 bits per revolution or decimal resolutions to 4096 counts per revolution.
The encoder operates from -40^oC to +85^oC and is resistant to shock and vibrations.
The magnetic encoder system is suitable for usage in industrial and medical applications.
Typical application is a robotic arm joint with a cable feed through the ring or a precision gearbox where the ring is attached onto the main transmission shaft. Custom design service for OEM integration is also available.
