The New Hotness

A Pogo Pin reference may be useful:

• P.. and R.. refer to Pin and Receptacle (a.k.a. socket), respectively
• Pxx  and Rxx = nominal pin diameter in 0.01 mm units: P50 = 0.48 mm

For pins, the suffix -hn indicates pin head shape, the most useful of which may be:

• B1: 45° cone
• J1: dome end
• Dx: large dome, also 1D
• Gx: cylinder
• Ex: large 90° cone, sometimes 1E
• T2 – large chisel

For sockets, the suffix -ntl gives:

• n – entry shape: 1 = shaped entry, 2 = straight entry
• t – termination: C = crimp, S = solder, W = wire
• l – length of wire in 100 mm units: 7 = 700 mm

From what I can find on eBay, all pins have 6 mm travel with typically 75 / 100 / 180 g spring force.

A picture ripped from the reference to forestall link rot:

Memo to Self: US-based eBay sellers charge three times more than Chinese sellers, but deliver in one-third the time.

[Update: Simon sends a link to Everett Charles Technologies, a pogo-pin manufacturer providing “Probably much more information than anyone should ever want”. Of course, eBay / Amazon junk may not meet any particular specs, so scale your expectations accordingly.]
