New Through-Hole Version 2mm Pitch Spring-Loaded Connectors
Mill-Max has added a through-hole version of 2mm pitch spring-loaded connectors to complement the series’
surface mount version. As always, real estate is at a premium in electronic packaging with designers demanding
tighter pitch interconnects that deliver high quality performance. These spring-loaded connectors (SLC’s) are an
appealing option combining both durability and space saving qualities. For board-to-board or device-to-board
connections with the additional security of through-hole mounting, these 2mm spring-loaded connectors are a
practical solution.
The connectors feature spring pins with a working travel of .0275” (0,7mm) and a maximum travel of .055” (1,4mm).
The initial, uncompressed, height of the connectors from the board surface is .295” (7,5mm). Mill-Max also offers
standard 2 mm pitch mating target connectors in through-hole and surface mount varieties, each with the option
of a flat or concave face. When mated with
through-hole target connectors,
at mid-stroke, a board to board height
of .425” (10,8 mm) is achieved; .408” (10,35 mm) with the
SMT targets.
The connectors feature a solder tail diameter
of .022” (,56mm) and a plunger diameter of .032” (,81mm) allowing adequate space for laying out the PCB holes,
pads and traces on both the solder and mating sides of the connectors.
These new through-hole SLC’s are offered in single row, series
836-22-0XX-10-001101
and double row, series
838-22-0XX-10-001101.
Standard availability is 2 to 50 positions for single row and 4 to 100 positions for the double
row. Both series are designed for manual placement into Ø .030±.003” plated through-holes in the circuit board
prior to hand, wave or reflow soldering.
The new 2mm pitch spring-loaded connectors maintain the quality and reliability of current Mill-Max spring pin
connectors by utilizing the same precision-machined components and internal spring components. Gold-plated
components and springs ensure the highest conductivity, corrosion resistance and durability. The spring-loaded
pins used in these connectors have a current rating of 2 amps continuous use (3 amps maximum.) The high tem-
perature plastic housing is suitable for all soldering processes and the connectors are RoHS compliant.
