Acting German Huntsler encoder classification and characteristics

Classification and characteristics of German Hensler encoders
The Hensler encoder can be classified as follows
1. Different classification according to the engraving method of the code disc
(1) Incremental type: a pulse signal is sent every angle of the unit (there is also a sine and cosine signal,
Then it is subdivided and chopped out with higher frequency pulses), usually A phase, B phase, Z phase output, A phase and B phase are pulse outputs with 1/4 cycle delay each other, which can be distinguished according to the delay relationship. It is inverted, 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: It corresponds to one circle, and each reference angle emits a value corresponding to the binary value of the angle. 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) 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.
