How to detect the encoder is good or bad?

Test for a normal general encoder is good or bad is to use the multimeter to check, the specific steps are as follows: 1, with appropriate amount of ohms range encoder 1 ~ 3 the total resistance, whether within the scope of the nominal value; 2, pens and pick up to 1 ~ 2 or 2 ~ 3 terminal, repeatedly varied slowly rotating encoder shaft, see if electric meter pointer changes continuously and evenly. Its value should be near zero the continuous variation between nominal value. Such as change discontinuous ( To beat) CLP resistance or change process is not stable, explain poor contact; 3, testing encoder terminals and shell ( Metal) And the insulation between the axis of rotation, to see whether the insulation resistance is enough big, Normal should be close to oo) ; 4, whether the power switch, measuring encoder contacts are in good condition. Shanghai electronics is 27 years old coder manufacturer, specializing in the production of various types of encoder, rotary encoder, straight and smooth encoder, rocker encoder, switch, encoders, take the motor encoder, resistance, linear and encoder handle designs and sizes are available according to customer's demand to customize, encoder models complete, can perfect replacement brand encoder, both at home and abroad to find find electronic encoder manufacturers.
