Electric photocell sensor encoder
The form of the encoder shaft: the shaft is extended and must be equipped with a coupler before it can be used; the hollow shaft, without a coupler, can be directly used on the other equipment.
The parameter that the encoder pays attention to: Resolution: That is, the number of pulses output per revolution when the encoder is working, whether it meets the design and use accuracy requirements
Magnetoelectric proximity switch encoder
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, and has nothing to do with the middle process of the measurement.
The working principle and function of the encoder: It is a rotary sensor that converts the rotation displacement into a series of digital pulse signals
The COM terminal of the encoder is connected with the PLC input COM terminal, and the A and B two-phase pulse output lines are directly connected with the PLC input terminal. When connecting, pay attention to the response time of the PLC input.
Rotary encoders output pulses during rotation, and the position (plc) is known by counting equipment. We usually use incremental encoders. The output pulse signal of incremental encoders can be directly input to the PLC, using the high speed of the PLC. The counter counts its pulse signal to obtain the measurement...
The biggest difference between an incremental encoder and an absolute encoder: In the case of an incremental encoder, the position is determined by the number of pulses calculated from the zero mark, while the position of an absolute encoder is the reading of the output code definite.
Encoders optical sensor encoder
The photoelectric encoder is an angle (angular velocity) detection device. It converts the angle input to the shaft into the corresponding electric pulse or digital quantity by using the photoelectric conversion principle. It has the advantages of small size, high precision, reliable work, and digital interface. . It...
The output form of the encoder: NPN open collector output, PNP open collector output, complementary output, voltage output, linear drive output. Determine the output form of the encoder according to what signal the subsequent device input can receive (which can be reflected in the naming rule).
The characteristic of the rotary encoder: no need to return to origin when starting (only for absolute type). The absolute rotary encoder outputs the rotation angle in parallel in absolute value.
The encoder reasonably selects the output signal transmission medium of the photoelectric detection device, and uses twisted-pair shielded cables to replace ordinary shielded cables.
Grating pollution This will reduce the signal output amplitude, so you must use absorbent cotton dipped in absolute alcohol to gently wipe off the oil
