Based on Hall Sensing Technology with 0°-360° Full Range Angle Sensing. Supports the brush settings to change the number of AB lines. This upgraded model has two additional resistors, eliminating the need for external resistors in IIC mode. 3.3-5.0V Operation Power Supply, build in EEPROM (Programing at VDD Greater than 4.5V). Independent Output Interface: 12C,SSl, ABZ, UVW, Analog/PWM and Push-Button Function on Z-Axis. Maximum Rotation Speed 55,000 RPM Output Propagation Delay 5 us Incremental ABZ Resolution 1-1024 Pulses per Revolution (PPR) User Programmable UVW Output Resolution 1-16 Pole-Pairs per Revolution User Programmable Color: Blue Material: PCB Package Contents: 1 x Magnetic encoder 1 x Magnet Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
