Product Name: 1pair Hall Sensor Speed Encoder Sensor Model NO.: RS030 Color: Color Style: Educational Toy Toy Department: All Material: metal Function: With Remote Control, Electric, Program Age: Above 14 Years Type: DIY Toys Trademark: DAGU Transport Package: Simple Package Origin: China HS Code: 90230090 Product Description 1Pair Hall Sensor Speed Encoder SensorSimple Encoder KitThe simple encoder kit from DAGU consists of two neodymium 8-pole magnets with rubber hubs and twohall-effect sensors terminated with 150mm (6inch) cable and 3 pin female servo headers.The magnets have 4 north poles and 4 south poles and are strong enough that the sensor can detect thepoles from more than 3mm (1/8inch).This means that the sensors do not need to be precisely mounted todetect the poles.The rubber hubs will press fit over most small motor and drive shafts used in low powergearboxes.A small screw may also be used to attach the magnets in some cases.The hall-effect sensors will work on voltages from 3V to 24V and include reverse polarity protection.Theopen drain output, when fitted with an external pullup resistor will drive any logic circuit from 3V to 24V andcan also drive a LED or any other small load less than 25mA.These sensors can plug directly into any DAGU, Arduino compatible controller and use the processorsinternal pullup resistors eliminating the need for any external components or wiring.Specifications:Supply voltage: 3V-24VSupply current: 4mA per sensorOutput voltage: 26V maximumOutput current: 25mA continuousOutput type: Open drainWiring:White wire: OutputRed wire: +3V to 24VBlack wire: Ground (0V
