Magnetoelectric encoder and wiring installation should pay attention to?
Magnetoelectric encoder is a kind of magnetic rotary encoder, it can measure distance, displacement, speed, Angle, is a precision device of electronic components, so when was the larger impact, it might damage the internal functions, so we should pay attention to use.
Magnetoelectric encoder considerations for the installation, don't give axis exert direct impact device.
The linkage between the encoder shaft and machine, should use flexible adapter.
At the shaft adapter, don't press hard into the.
Even if using the adapter, because of the bad device, may also be added to the axis of is greater than promised to load load, or dial the core representation, therefore, should be pay attention to.
Bearing life spans about applying condition, affected by the bearing load of especially big.
Such as rules than the load bearing load is small, can significantly extend bearing life spans.
Second, the oscillation.
On the oscillation on the rotary encoder, often can become false pulse attack because of it.
Therefore, to set the place, the installation place.
Number of pulses per forward as the more, rotate the narrower slots of the disk slot interval, the more easily affected by the oscillation.
In low-speed rotation or suspension, add spin groove on the shaft or the ontology of oscillation (disk vibration, false pulse may attack.
Magnetoelectric encoder wiring note magnetoelectric encoder error wiring and cohesion, and it might damage the internal circuit, so when wiring should fully pay attention to the following: 1.
Wiring shall be carried out under the power OFF state, when power on, if you touch the power supply output line, sometimes will damage the output circuit.
If wiring fault, sometimes damage the internal circuit, so the wiring should be energetic note the polarity of the power supply, etc.
If parallel wiring and high tension line, power line, sometimes into damage were induced to form misoperation, so be wiring separately points out.
The extension wire, should be under 10 m.
And because the wire spread capacity, waveform of rising and falling time is longer, when in doubt, choose the schmidt circuit for plastic waveform.
In order to prevent induced noise, etc. , to use the shortest interval wiring.
To the integrated circuit input, especially needs attention.
Extension wire, conductor resistance and the influence of the capacitance of the line, the waveform of rising and falling time longer, easy occurred between signal trouble (
Small, so using resistance, the line between the capacitance low wire (
Twisted-pair cable, shielded wire)
About HTL with symmetric negative signal output of the encoder, signal transmission of up to 300 meters apart.
Rotary encoder used in the poor environment need to be on the outside of the encoder with a protective shell, to ensure that the encoder products are not damaged.
Shanghai electronics is 27 years old coder manufacturer, specializing in the production of various kinds of rotary encoder, research and development production of magnetoelectric encoder performance not easily affected by dust and condensation;
Its simple and compact structure, non-contact, long life, high and low temperature resistance, resistance to vibration, fast response speed and low cost, high cost performance of a rotary encoder, find magnetoelectric encoder manufacturer is looking for electronic.
