4 Pin Power JST Male Connector Straight 2mm Pitch: A Detailed Breakdown
The 4 Pin Power JST Male Connector Straight 2mm Pitch, also known as a JST PH connector, is a compact and versatile connector commonly used in low-power electronic applications. This connector provides a reliable and easy-to-use solution for connecting wires to PCBs (Printed Circuit Boards) or other electronic components.
Description
The connector consists of two parts:
- Housing: This is the plastic shell that holds the metal pins. It has a straight orientation, meaning the pins and the cable entry are aligned in a straight line.
- Crimp terminals: These are small metal contacts that are crimped (mechanically attached) to the ends of wires. The terminals then slide and lock into the housing, creating the electrical connection.
The 4 Pin version offers four individual connection points, allowing for the transmission of power and/or data signals.
Specifications
| Feature | Specification |
|---|---|
| Connector Type | JST PH |
| Number of Pins | 4 |
| Pitch | 2.0mm (distance between the centerlines of adjacent pins) |
| Mounting Type | Through-hole (pins are inserted into holes on the PCB and soldered) |
| Gender | Male |
| Current Rating | Typically 2A (although some variants may be rated up to 3A) |
| Voltage Rating | Typically 100V (may vary depending on the manufacturer) |
| Wire Gauge | Typically 24-30 AWG (American Wire Gauge) |
| Operating Temperature | -25°C to +80°C |
Features
- Compact size: The small footprint (around 5.2mm x 2.0mm x 2.3mm for the housing) makes it ideal for applications with limited space.
- Ease of use: The crimp terminals allow for quick and reliable connection of wires without soldering.
- Low cost: JST connectors are generally inexpensive, making them a cost-effective solution for many projects.
- Versatility: The 4-pin configuration allows for transmitting both power and control signals.
- Secure connection: The locking mechanism ensures a secure connection that resists accidental disconnection due to pulling or vibration.
- Wide availability: JST connectors are widely available from various electronics suppliers.
Applications
4 Pin JST Male Connectors are commonly used in a broad range of low-power electronic devices, including:
- Battery packs: Connecting batteries to electronic devices like RC toys, drones, and small robots.
- LED lighting: Powering LED strips and modules.
- Sensors: Connecting sensors to microcontrollers for data acquisition.
- Audio/Video devices: Connecting small cameras and microphones.
- Consumer electronics: Used in portable devices like calculators and remote controls.
- Prototyping: Quick and easy connection of components during electronics prototyping.
Developments
The JST PH series is a well-established connector family with ongoing development to improve functionality and cater to specific application needs. Here are some advancements:
- Increased current rating: Newer versions like the PH-4A offer a higher current rating (up to 3A) for applications requiring more power.
- Pre-crimped wires: Pre-crimped JST connectors with attached wires are available for even faster assembly.
- Locking variants: Some JST PH connectors have a locking tab mechanism for an extra layer of security in critical applications.
- Surface mount variants: Surface mount JST PH connectors are available for PCB designs where through-hole soldering is not feasible.
While the core functionalities remain the same, these developments provide users with more options to tailor the connector choice to their specific needs.
In conclusion,
The 4 Pin Power JST Male Connector Straight 2mm Pitch is a widely used and reliable connector for low-power electronics applications. Its compact size, ease of use, and affordability make it a popular choice for hobbyists, makers, and professionals alike. With ongoing developments offering increased capabilities, the JST PH series remains a relevant and versatile solution in the ever-evolving world of electronics.
