Encoder is a kind of common electronic components, widely used in automotive electronics, home electronics, multimedia, mixer, interphone, electronic toys, household appliances, aerospace, military industry and other fields, the friends will receive some purchasing department please buy encoder needs to apply for, about the encoder procurement selection, to share the following experience, hope to help friends can better choose the right type for encoder.
Encoder procurement type selection reference 1:9 models,
Double or single union)
With switch or not)
Size or schedule purchasing an encoder, the first thing to understand is the encoder model or type.
So the following is a general direction.
Are the first thing to look at the dial encoder or rotary encoder or straight slide encoder, or just trimming resistance.
Is determined, and then determine the dial encoder is single union or a double?
How much is the sliding trip ah.
Only to make sure these a general pattern.
And this the factors that affect the price.
2: resistance and linear requirements.
After determine the appearance of the encoder, then will know how much is the value of the encoder, resistance to accept how much is the deviation?
What is the value of linear and so on.
B10K, for example, that marks the encoder is 10 k value, the linear B.
3: shaft type or sliding handle type or dial type and size, length, etc.
Such as a rotary encoder with handle, first is to determine the die casting iron handle or plastic handle, is the plum flower round handle or semicircle, how long?
With or without nut, etc.
Dial to see is black or white, the diameter is how much, how much is the thickness, etc.
These are all should make it clear.
4: the form of terminal.
This should see terminal is terminal straight or curved terminals.
Or what was in terminal with the handle Angle can also.
Is straight foot 180 degrees, 90 degrees is bent feet.
5: wiring way.
With circuit board is to use what the connection mode of the encoder is inserted with weld line or directly to the circuit board and so on.
6: point with and without.
Rotary encoder have locate in the middle?
These general sliding encoder will meet, part of the shank rotary encoder will also have such problems.
7: tap the presence of in the middle.
This should see clear.
8: the purpose of the encoder.
What do you purchase this encoder is used on?
Is a headset, or sound or is a toy and so on.
Is used to move light or adjustable speed or adjust the sound?
These will affect the quality of production.
9: soldering method: hand welding or soldering tin stove.
Do you purchase this encoder is solder by hand or with soldering tin stove.
The technology and material requirements for the encoder is not the same.
Purchase encoder, supplier brand, strength, power supply is very important, should choose a suitable supplier for a long time cooperation with the operation and development of the company's products.
Shanghai electronic 27 years, specializing in the production of encoder encoder models complete, over the years has been with the strict quality requirements for unanimous approval and favorable comment of the new and old customers at home and abroad, by domestic well-known brand is defined as the designated suppliers, trustworthy!
Find find electronic encoder supplier.
