Compact, low cost magnetic encoders from POSITAL have what it takes for elevator applications

POSITAL’s versatile Magnetocode (MCD) series encoders – used in a wide variety of motion control applications – are also a great fit for elevator control systems

Rugged, reliable and very cost-effective, these absolute rotary encoders are available in single or multi-turn versions and can be ordered with a CAN-open-certified digital interface that supports the CiA 417 lift application profile. (CiA 417, an extension to the CANopen standard, addresses interoperability of components in elevator control systems.) MCD encoders with DeviceNet interfaces will be available later in 2010.

POSITAL MCD encoders feature ball-bearing mounted shafts for ruggedness and a highly accurate non-contact position measurement technology that en-sures reliability, availability and long service life. Many internal parameters can be programmed via the digital interface, including operating mode, data trans-mission rates, zero offset, direction of rotation and number of steps per turn (up to 4096). MCD encoders also feature a unique internal system that keeps track of absolute position readings, even after power interruptions. With an outside diameter of only 34.5 mm, MCD encoders fit easily into tight spaces.
