Connection Method of Three-legged Adjustable Resistance

 

Tripod adjustable resistance connection has a unique role, I believe many people have heard of this connection, in view of these different requirements, Dongguan headphone socket manufacturers to introduce tripod adjustable resistance connection.

Three-legged adjustable resistance, literally, is a three-legged adjustable resistance. Although they are all three-legged, they are divided into vertical three-legged adjustable resistance and horizontal three-legged adjustable resistance. Some people don't know how to distinguish between vertical and horizontal. In fact, it is very simple. Let's give you a few examples.

1. Carbon film adjustable resistance RM085C-V1, carbon film adjustable resistance RM065-V5, carbon film adjustable resistance RM065-V1, ceramic adjustable resistance RM085G-V3, ceramic adjustable resistance RM085G-V6 and ceramic adjustable resistance RM085G-V2 are all horizontal adjustable resistors.

2. The carbon film adjustable resistance RM063-H1, the carbon film adjustable resistance RM065-H5, the carbon film adjustable resistance RM085C-H2, the ceramic adjustable resistance RM085G-H3, the ceramic adjustable resistance RM085G-H4 and the ceramic adjustable resistance RM065G-H3 all belong to the vertical adjustable resistance.

Did you find a rule? In fact, V stands for horizontal and H stands for vertical. Is that very simple? Let's look at the product itself.

Xiaobian just wants to tell you that from the product itself, people who are not professional are not clear whether they are vertical or horizontal. We can get a lot of information from the product model itself. Whatever it is, the connection principle of three-legged adjustable resistance is almost the same. The connection method of three-legged adjustable resistance mainly pays attention to a few points:

First, the three-legged adjustable resistance is the two ends of the resistance. If there is a 100K adjustable resistance, the resistance value of the two legs is 100K. To measure the resistance value of the middle foot and any end foot, it must depend on the position of the handle. If the middle foot and any end foot are rotated to the middle position, the middle foot and any end foot are 50K.

2. The foot in the middle of the three-legged adjustable resistance is a sliding contact, and the foot on both sides is a fixed resistance value. Generally, it varies from 0K to mK. Access according to its requirements is OK.

Knowing the rules above, and referring to the six-foot potentiometer connection method, the role of adjustable resistance and the different roles of resistance and adjustable resistance in the circuit, is it very simple for the three-foot adjustable resistance connection method?
