Product Usage
SUMICON 1600 Series Crimp Type Connector Usage
- 1. Take care when removing the connectors to pull out by the housing and not tug on the wires.
- 2. The male terminals of the connectors will be bent if the connectors are twisted when being removed. Take care to pull the characters out straight.
- 3. The plastic locks are sufficiently strong to ensure that the connector engagement will not be loosened by vibration or the weight of the wires. Their strength is not sufficient for other loads. When strength for some other load is required, use the top-touch lock type plug case (common for both solder and wrapping types.)
- 4. Both gold-plated and silver-plated terminals are available. Use the gold-plated type in adverse environments. In other environments the manufacturer recommends the economical silver-plated type.
- 5. Use a manual crimping device for low-volume crimping and maintenance. For high-volume crimping the manufacturer recommends their automatic crimping machine.
- 6. For plug-in uses, the manufacturer recommends the Sumicon 1600 Series solder or wrapping types for improved functionality.
