Molex Pin Header, Tin-Plated Brass Contacts, Flame-Retardant - KK 254 Series - 22-27-2051


Use this pin header from Molex to create secure electrical connection points on a PCB. Its five circuits mean you can wire multiple devices using one unit, which saves you time and makes the most of board space. Thanks to its friction lock, you're assured of secure retention when it's mated to a compatible part. For safety, this pin header is flame-retardant, so it's unlikely to contribute towards the spread of a fire.

Features & Benefits


• Low halogen, so releases minimal toxic fumes when hot

• Non-conductive nylon body cuts out the risk of electric shocks

• Low-resistance tin-plated contacts offer reliably high conductivity

Applications


• Security centres

• Transportation industry

• Electronics manufacturing

• Industrial automation

How do I attach this pin header to a circuit board?


The connector has PC tails that let you easily solder it to a circuit board.
