Molex Mini-Fit Jr Straight PCB Header, 8 Way, 2 Rows - 5566 Series - 39-28-1083


Keep your electrical wires securely connected to your PCB (printed circuit board) with this Molex straight PCB header. The device can accommodate up to eight wires for versatile use, and the straight body orientation ensures your wires are clearly laid out for ease of organisation and identification. It has a high voltage rating of 600V for use in high-powered applications. Thanks to its tin-plated brass contacts, the unit is resistant to corrosion for reliable, long-lasting performance in harsh environments. This header is shrouded to reduce electrical interference and ensure high-quality transmission.

Features & Benefits


• Wide operating temperature range of -40°C to +105°C for use in extreme environments

• Terminals are polarised and keyed to prevent mismating

• Positive locking mechanism keeps wires securely in place, even in the event of heavy vibrations

• Durability of up to 30 mating cycles for long-lasting use

• Two-row design keeps wires organised while occupying less space than a single-row header

Applications


• Industrial networks

• Harness manufacturers

• Non-sealed applications

• Electronic control modules

Is this PCB header fire-safe?


Yes, the nylon material of this PCB header is flame-retardant, so it won't promote the spread of flames in the event of a fire.
