, rss electronica mechatronic systems MDB20 - Magnetic encoder module Passion for Excellence Based on Dipole Magnet and Hall Sensors MDB20 magnetic rotary encoder module has a precision sensor having an integrated Hall element for scanning a permanent Dipole magnet. The Sensor itself generates a constant amplitude Sine and Cosine voltages that is used for angle calculations. These Sine and Cosine signals are further interpolated to get the Incremental or Absolute signals with resolutions up to 14 bits per rotation. MDB20 module is a 20mm PCB assembly which can be used in any small designs with ease of installation. Salient Features: 20mm Circular PCB assembly module C& Operates on 5V power supply C& Variety of outputs supported like Analog Sin-Cos output, Incremental RS422, Absolute SSI and BiSS-C protocol Supports up to 14 bits (16384 positions) per rotation Absolute and Incremental output Accuracy +/- 0.5 deg High Speed operation up to 20000 rpm at finest resolution 3600 CPR also available to give angular resolutions easier for mathematical calculations Suitable for applications like motor control, Medical instrumentation, paper and textile industry, Industrial automation and many more Available models: MDB20AS - Analog single ended Sine Cosine output with a single sine-cosine cycle per rotation MDB20AC - Analog complementary Sine Cosine output with a single sine-cosine cycle per rotation MDB20LV - Analog Linear voltage output with 10bit resolution MDB20IR - Incremental RS422 A, B and Z output with up to 16384 counts per rotation (CPR) MDB20SB - Absolute output on Synchronous Serial interface (SSI) with Binary data up to 13 Bits per rotation MDB20SG - Absolute output on Synchronous Serial interface (SSI) with Grey coded data up to 13 Bits per rotation MDB20BC - Absolute output on BiSS-C data up to 14 Bits per rotation
