Sparkfun Wheel Encoder Kit

Key Features A simple add-on to any wheeled robot that can help measure the speed or distance the chassis travels Requires a supply voltage of 3-24V, 4ma Hall sensors include reverse polarity protection Detect the poles at more than 3mm. Sensors plug directly into any DAGU This is the Wheel Encoder Kit from DAGU, a simple add-on to any wheeled robot that can help measure the speed or distance the chassis travels. Each wheel encoder kit consists of two neodymium 8-pole magnets with rubber hubs and two hall-effect sensors terminated with 150mm cables and 3-pin female servo headers. These wheel encoders require a supply voltage of 3-24V with a supply current of 4mA.Item Specific2 - neodymium 8-pole magnets2 - rubber hubs2 - Hall-effect sensors (6in cable)Supply Voltage: 3-24VSupply Current: 4mA per sensorOutput Voltage: 26V MaxOutput Current: 25mA Continuous
