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.

Improve space efficiency on your printed circuit boards (PCBs) with this right-angled pin header from 3M. This compact connector lets you make up to 20 different connections on a single board, saving installation time and space. It consists of pins that are soldered directly to the PCB and it can be used for both wire-to-board and board-to-board connections. These pins are made of a copper alloy material that's plated with gold, so you don't have to worry about decay due to rust.

• Exposed solder tails for simple cleaning and maintenance• Right-angle body orientation for easy access in hard-to-reach areas• Glass-filled polyester housing for insulation and impact resistance• Centre slot polarisation to prevent incorrect insertion and reduce installation time• Flame-retardant for use in extreme environments

• Electronic circuit integration• Adruino Uno and Raspberry Pi single-board computers (SBCs)

This connector is designed for through-hole mounting, which involves the installation of the component onto a printed circuit board with leads using plated holes. It was the most common mounting procedure before the invention of surface mount technology (SMT) and is still widely used.
