Molex Pin Header, Brass Contact Material, Unshrouded - KK 254 Series - 171857-3002

Make a connection you can rely on with this pin header from Molex. As it has two male pin connectors set at a right angle to the main body, you can use it to form a connection between two PCBs horizontally. Installation is simple via the through-hole mounting method. All you need to do is push the pins into holes drilled in the PCB and then solder them in.

• Brass contacts with tin plating for high conductivity and resistance to corrosion

• Standard pitch size of 2.54mm for hassle-free compatibility

• Unshrouded, so saves space

• 250V rating to work with low-voltage applications

Applications

• Domestic appliances

• R&D laboratories

• Automotive manufacturing

Can I use this pin header in extreme conditions?

Yes, it has a broad operating temperature range between -40°C and +105°C, so you can use it in harsh environments.
