Key Features:
- Housing color: Black
- Number of positions: 2
- Pitch: 2.54 mm
- Dimensions: 5.05 mm (L) x 6.58 mm (H) x 15.24 mm (D)
- Mounting Type: Free hanging
4. Installation and Setup
The Molex 50-57-9402 connector is designed for straightforward assembly. Please note that this housing typically requires separate crimp terminals (pins) to be inserted into the housing for a complete connection. These pins are generally not included with the housing and must be acquired separately.
Installation Steps:
- Prepare Wires: Strip the insulation from the ends of the wires that will be connected to the terminals.
- Crimp Terminals: Crimp the appropriate Molex terminals (pins) onto the stripped wire ends using a suitable crimping tool. Ensure a secure and proper crimp for reliable electrical contact.
- Insert Terminals into Housing: Carefully insert the crimped terminals into the designated cavities of the 50-57-9402 housing. Ensure the terminals are oriented correctly and click into place, indicating they are fully seated and locked.
- Connect: Once both terminals are securely in the housing, the receptacle connector is ready to be mated with a compatible male header or plug connector. Align the connectors and push them together until they fully engage.
Note: Refer to the specific datasheet for the terminals you are using for detailed crimping instructions.
5. Usage
Once installed and connected, the Molex 50-57-9402 connector provides a reliable electrical connection for two circuits. Its design ensures a secure fit, preventing accidental disconnections under normal operating conditions. This connector is suitable for low-power signal and power applications within its specified voltage and current ratings.
6. Maintenance
The Molex 50-57-9402 connector is designed for long-term reliability and requires minimal maintenance.
- Cleaning: If necessary, gently clean the exterior of the connector with a dry, lint-free cloth. Avoid using harsh chemicals or abrasive materials.
- Inspection: Periodically inspect connections for any signs of wear, corrosion, or damage. Ensure the connector remains securely mated.
7. Troubleshooting
If you encounter issues with your Molex 50-57-9402 connector, consider the following:
- No Electrical Connection:
- Verify that the correct terminals (pins) have been crimped onto the wires and are fully inserted into the housing. This housing does not come with pins, which are essential for electrical contact.
- Ensure the connector is fully mated with its counterpart.
- Check for any bent or damaged terminals within the housing or on the mating connector.
- Loose Connection:
- Confirm that the terminals are properly locked into the housing. A slight tug on the wire should not pull the terminal out.
- Ensure the mating connectors are fully engaged and the locking mechanism (if present on the mating part) is secure.
- Difficulty Mating:
- Check for proper alignment of the connector with its mating part.
- Inspect for any debris or foreign objects obstructing the connection.
