Encoder installation must know the common sense

Encoder is a kind of sophisticated electronic components, install the encoder, in order to maintain the performance does not change, must follow the principle of the installation of the encoder, the use of some mistakes can lead to poor encoder or failure, directly affect the service life of the encoder, the encoder must understand the installation and you about common sense. A, heat dissipation problems encoder in use, the resistor body heat will cause the rise of temperature of the encoder itself. Must be in the form of convection, conduction, radiation and heat dissipation, in which case or floor cooling way of conduction is a very important. If the encoder to install enough properly, heat dissipation is bound to be affected. Even cause damaged encoder temperature was too high. Especially those larger encoder, power consumption and electronic equipment, instrument miniaturization and can form the internal temperature of rat for heat dissipation between serious should pays much attention to. Often installed on the thermal conductivity of good metal base plate, to ensure good heat dissipation. At the same time, also need to consider other fever yuan, within the vicinity of the encoder device of distribution. Should be considered when necessary to provide ventilation and cooling conditions, to ensure the safety in the encoder can use. Second, the mounting problems when installing encoder, fixed nut or lock the lock nut of the encoder cannot too tight, otherwise the axis of rotation will be out of shape, and the rotation will be uneven. In this way, torque changes will occur. For locking the encoder, locking torque is lower than the standard should pay special attention to the following. Locking torque according to the turning sleeve diameter thickness and different materials used in industry. Generally speaking, aluminum shaft worst, casting axis, brass, steel shaft, in turn, hardened. In addition, after the nut lock, rotation about LMM above higher than the surface of the nut. Three, terminal and circuit of welding because of the encoder raises the soldering terminal or lead is shorter, so the miniaturization of printed circuit boards, or in the hybrid integrated circuit for welding later must pay attention to add hot temperature not too high, go not too long, The soldering iron welding, temperature of 350. C, 35270. C, 5 s) 。 Otherwise. The radiant heat generated in the melting of solder, solder splash, printed circuit board bending or substrate deformation, etc. , can be the cause of the encoder failure. If the attachment errors, remove, especially from printed circuit boards or hybrid integrated circuit substrate to put on line, more should be cautious. In addition, when welding, flux should use less as far as possible, more can't let flux immersed inside the encoder, otherwise, cause poor contact. In the process of welding circuit, between the terminal or terminal and gold w g, bottom clearance, and other conductors shall strictly avoid have solder fan into the phenomenon, must carry on the strict removal process after welding. Shanghai electronic products specializing in the production of encoder for 27 years, specializing in the production of various kinds of rotary encoder, switch, encoders, straight and smooth encoder, rocker encoder, take the motor encoder, etc. Full, encoder type can be perfect to replace brand encoder, both at home and abroad can contact customer service to replace the product details! Can provide customers with a axis type, long axial length and working parts, shaft sleeve type, long sleeves, the resistance and its linear error values, professional custom, looking for looking for electronic encoder manufacturers.
