Magnetic encoders from Posital's MCD (Magnetocode) series, which reliably measure absolute positions by means of a Wiegand sensor, are now available as heavy duty models for demanding environments. Due to a flange construction with impact protection for the shaft seal, the stainless steel device is IP69K protected and withstands even high-pressure cleanings. The mechanically robust housing, which provides protection against strong magnetic fields, is shock-resistant up to 300G, allowing users to install the encoders in applications such as rock drilling machines. Featuring grooved ball bearings with high load ratings that are spaced accordingly, the encoders are suitable for high radial and axial shaft loads (up to 300 N). It can be exposed to salt water, such as in-port applications.
The magnetic encoder technology offers users a range of benefits. Since measuring is contact free, the unit is very robust. With the Wiegand technology, it is very cost-efficient, not requiring a gearing unit or batteries to store measured revolutions. The encoder registers one revolution with a maximum resolution of 12bit; up to 15bit is available for revolution measurement. The company provides models with a CANopen or SSI interface and units with an analogue interface which can replace multi-turn potentiometers. With a diameter of merely 36.5mm, it is available as hollow or solid shaft versions suitable for applications with constrained space.
