1. Introduction
This manual provides instructions for the QINIZX 1.0mm Diameter Tube Socket Pins, designed for use with various glow tubes and fluorescent tubes, including the IN-18 model. These pins facilitate secure and reliable electrical connections in electronic projects.
2. Product Overview and Features
The QINIZX tube socket female pins are crafted from tinned brass with a gold-plated finish, ensuring premium quality and excellent conductivity. They are specifically engineered for compatibility with 1.0mm diameter tube pins.
- Material: Tinned brass, gold-plated.
- Compatibility: Designed for 1.0mm diameter pins.
- Applications: Suitable for IN12, IN18, QS27-1, SZ4-1, YS27-3, QS30-1, and similar glow/fluorescent tubes.
- Elasticity: Features moderate elasticity for secure pin retention.
- Quantity: Each package contains 100 individual socket female pins.
Compatibility Note: These pin receptacles are suitable for 1mm tube pins. They are not compatible with tubes such as IN14, QS18-12, or YS13-3, which typically have different pin diameters.

3. Setup and Installation
The pins are delivered connected in strips. Before installation, they must be gently separated.
- Separation: Carefully break off individual pins from the connecting strip. This can usually be done by hand or with small pliers, applying gentle pressure at the connection points.
- Insertion: Insert the separated female pins into the desired circuit board (PCB) or breadboard holes. Ensure the pins are oriented correctly and fully seated.
- Tube Placement: Once the female pins are installed, the corresponding glow or fluorescent tube can be gently inserted into the pin receptacles. Ensure all tube pins align with the socket pins to avoid bending.

5. Maintenance
These tube socket pins require minimal maintenance. To ensure optimal performance and longevity:
- Keep pins clean and free from dust or debris.
- Avoid excessive force when inserting or removing tubes to prevent bending or damaging the pins.
- Store unused pins in a dry, non-corrosive environment.
6. Troubleshooting
If experiencing connection issues:
- Poor Connection: Verify that the tube pins are straight and fully inserted into the socket pins. Ensure the socket pins are securely seated in the PCB.
- Incompatible Tube: Confirm that the tube being used has a 1.0mm pin diameter. These pins are not compatible with tubes requiring different pin sizes (e.g., IN14, QS18-12).
- Damaged Pin: Inspect individual socket pins for any signs of bending or damage. Replace any compromised pins.
