Winch motor encoder HS35F-100-R2-SS-1024-ABZC-5V/V-SM18-EX
Delivery time 2 weeks
An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a signal that can be used for communication, transmission, and storage. The encoder converts an angular displacement or a linear displacement into an electrical signal, the former being called a code wheel and the latter being called a code ruler. According to the readout mode, the encoder can be divided into contact type and non-contact type; according to the working principle, the encoder can be divided into two types: incremental type and absolute type. The incremental encoder converts the displacement into a periodic electrical signal, which is then converted into a counting pulse, and the number of pulses is used to represent the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the start and end positions of the measurement, regardless of the intermediate process of the measurement.
1. Different classification according to the engraving method of the code disc
(1) Incremental type: a pulse signal is sent every time the unit is rotated (there is also a sine and cosine signal,

Then subdivide it, chopping out the higher frequency pulse), usually the A phase, B phase, Z phase output, A phase, B phase is the pulse output of 1/4 cycle delay each other, can be distinguished according to the delay relationship It is reversed, and 2 or 4 times can be multiplied by taking the rising and falling edges of phase A and phase B; the Z phase is a single-turn pulse, that is, one pulse per revolution.
(2) Absolute value type: that is, corresponding to one circle, each reference angle gives a unique binary value corresponding to the angle, and the external circle device can perform recording and measurement of multiple positions.
2. According to the output type of the signal, it is divided into: voltage output, open collector output, push-pull complementary output and long-line drive output.
3. Classification by encoder mechanical installation
(1) Shaft type: There are shaft type and can be divided into clamping flange type, synchronous flange type and servo mounting type. [2]
(2) Bushing type: The bushing type can be divided into half-air type, full-empty type and large-diameter type.
4, with the working principle of the encoder can be divided into: photoelectric, magnetoelectric and contact brush type.
