In the process of using encoder taboo

Most of the resistance of the encoder USES much carbonated made of synthetic resin, so the use of should avoid contact with the following chemicals: ammonia, other amine, aqueous alkali, aromatic hydrocarbon, ketone and lipid hydrocarbon, strong chemicals ( High ph) And so on, otherwise it will affect their performance. Encoder in terminal should avoid using water capacitive when welding flux, otherwise will fuel oxidation and metal mold material; When used to avoid using inferior flux, bad soldering tin may cause difficulties, lead to poor contact or break. If encoder of the terminal when soldering welding temperature too high or too long can lead to damage to the encoder. Pin type terminal welding should be at 235 ℃ & plusmn; 5 ℃, 3 seconds to complete, the welding should be from the encoder frame 1. More than 5 mm, do not use when welding the wear PCB solder flow; Welding line terminal welding should be at 350 ℃ & plusmn; 10 ℃, 3 seconds to complete. Terminal in use process should avoid weight, otherwise easy to cause poor contact. When welding, rosin ( Flux) Entering the height adjustment of the press plate properly, should avoid flux into internal encoder, otherwise will cause brush with poor contact resistance body, produce INT, noise is undesirable. The encoder is best applied to voltage regulation, structure and connection mode should select '1' feet grounded. Should avoid to use current adjustment type structure, because the contact resistance between the resistance and the contact piece against high current pass. Encoder surface should avoid condensation water droplets or exist, avoid in damp places, in order to prevent the insulation deterioration or cause a short-circuit. Install 'rotary type encoder in a fixed nut, strength shoulds not be too tight, in order to avoid damage the teeth or turn bad, etc. ; When installing 'iron shell straight slide type encoder, avoid to use long screw, otherwise may impede the movement of the sliding handle, even directly damage the encoder itself. In the process of the set of encoder knob, the thrust cannot be used too much ( No more than 'specification' axis of the parameters of the push pull) , otherwise will may cause damage to the encoder. The encoder (rotary operating force Rotating or sliding) Can follow the rise of temperature and light weight, tight with temperature decrease. When used in low temperature environment indicate if the encoder, in order to use a special resistance to low temperature grease. Encoder shaft or sliding handle when using the design should be as short as possible. Shorter axis or smooth shank length feel better and stable. Whereas the longer shaking, the greater the feel is easy to change. Encoder can withstand the power of carbon membranes surrounding temperature is 70 ℃, when using a temperature higher than 70 ℃ could lose its function.
