Molex Female Connector Housing, 18 Way, 2 Rows - Mini-Fit Jr Series - 39-01-2180


Opt for this connector housing from Molex to safely link crimp terminals to your PCB. It features nylon housing that's durable and can withstand impact, so it's a practical choice for use in harsh environments where rough handling is likely. As this material is also an insulator, it can help protect operators from the risk of electric shocks. Compact dimensions of 39 (length) x 14.1 (width) x 19.6mm (depth) mean you can use it in setups with limited space. A pitch of 4.2mm provides a safe distance to stop conductors from touching each other, preventing short circuits. A connector housing like this is a common component in personal and industrial computer systems.

• Rating of 13A for high-current applications
• Wide operating temperature range of -40°C to +105°C for safe use in challenging conditions
• 18 contacts for multi-circuit signal transmission
• Positive locking mechanism prevents accidental unmating due to shock or vibration

Applications


• Automotive equipment
• Agricultural machinery

Is this connector housing safe to use in the event of a fire?
