From 3M, the 2500 series 2.54 x 2.54mm four-wall shrouded PCB headers with a low profile, space saving design are available in SMT, through hole, straight and right angle PCB mounting configurations.

These 2.54mm 2500 series PCB headers have centre slot polarization to facilitate accurate insertion and dual slot polarization making the connector compatible with other competitive polarization designs. Versions of these 2500 series PCB header connectors are available with a high temperature (260°C) black PCT housing (part numbers pre-fixed with 'N') which are suitable for 'no lead' soldering operations, through hole PCB headers with high temperature housings are suitable for 'paste in hole' reflow soldering techniques.

• Part numbers (N)25xx-xx02 are for use with a 1.57mm PCB thickness
• Part numbers (N)25xx-xx03 are for use with a 2.39 to 3.18mm PCB thickness
• A latch is available for use with these headers see stock number 192-7782
• Socket retainer clips are also available for these shrouded PCB headers, see stock number 323-8220 typically

• Low profile, space saving design
• Center slot polarization prevents mis-insertions and reduces insertion time
• Dual slot polarization means broader compatibility with competitive polarization designs (not 6, 8 or 10 pos.)
• Optional retainer clip for locking sockets in place and increasing connection reliability in vibration prone environments

PCB Headers are used to connect two PCB boards together. This makes it highly efficient by not having to solder the board together or wire them and will save you time. It also makes it very easy to remove the second board if anything fails.

3M are a reliable name in computing and electronic connection. Combined with RS Components excellent customer service, 3M provides a range of specialist connectivity solutions for a variety of industries and applications.

Use this PCB header from 3M for reliable board-to-board or wire-to-board connections. It's designed for solder termination, giving you a secure link, even in vibrating systems. To ensure a dependable connection, its contacts are made of highly conductive and corrosion-resistant gold-plated copper alloy. Thanks to a low operating current of 1.75A, this header is a good choice for use in low-power applications.

• Wide operating temperature range of -55°C to +105°C for use in harsh environments
• Center slot polarisation helps prevent improper mating
• 16 contacts arranged in two rows for space efficiency and an organised setup

• Computers and laptops
• Medical equipment
• Avionics

The housing is made from PCT, which is resistant to impact and chemicals, so is safe for use in demanding conditions.
