JST connectors are a type of micro connector that can be used to connect various electronic devices, such as batteries, circuit boards, sensors, lights, etc. There are various types and specifications of JST connectors, let's take a look.
-Types of JST connectors
-The type of JST connector mainly consists of two letters, representing the series and spacing of the connector. For example, JST-PH represents a PH series connector with a spacing of 2.0mm.
-There are many series of JST connectors, each with different characteristics and uses. For example, the PH series connectors are suitable for small electronic devices, with high density and reliability; The XH series connectors are suitable for high current equipment and have high voltage resistance and high temperature performance; The SH series connectors are suitable for ultra small devices, with ultra-low height and ultra-small spacing.
-The spacing of JST connectors refers to the distance between the pins of the connector, which determines the size and capacity of the connector. There are various spacing options for JST connectors, ranging from 0.8mm to 5.0mm. The smaller the spacing, the smaller the connector, but the smaller the capacity; The larger the spacing, the more stable the connector is, but it also takes up more space.
-Specification of JST connector
-The specifications of JST connector mainly consist of three numbers, which represent the number of pins, current, and voltage of the connector. For example, JST-PH 2P 2A 100V represents a 2-pin connector in the PH series, with a current of 2 amperes and a voltage of 100 volts.
-The number of pins in a JST connector refers to the number of metal contact points on the connector, which determines the number of signals or power supplies that the connector can transmit. There are various stitches for JST connectors, ranging from 1 to 20. The more pins, the more information the connector can transmit, but the wiring is also more complex; The fewer pins, the less information the connector can transmit, but the simpler the wiring.
-The current of the JST connector refers to the maximum current that the connector can withstand, which determines the amount of power that the connector can transmit. There are various currents for JST connectors, ranging from 0.1A to 10A. The greater the current, the greater the power that the connector can transmit, but the greater the heat generation; The smaller the current, the smaller the power that the connector can transmit, but the smaller the heat generation.
-The voltage of the JST connector refers to the maximum voltage that the connector can withstand, which determines the amount of energy that the connector can transmit. There are various voltages for JST connectors, ranging from 30V to 250V. The higher the voltage, the greater the energy that the connector can transmit, but the higher the voltage resistance requirement; The lower the voltage, the less energy the connector can transmit, but the lower the voltage resistance requirement.
In summary, JST connectors are a type of micro connector that comes in various types and specifications. When choosing a JST connector, it is necessary to choose the appropriate type and specification based on one's own equipment and needs.
