either one which transition out to either surface mount style or solder style soldertail to
accommodate various P.C. board thickness. The contact pattern in the mating area will have short
and long terminals in a specific pattern that results in a 0.5mm (0,020’) differential between contact
points in the long and short terminals. (This allows for first mate-last break capability - see
respective product prints for location of short and long terminals.)
The receptacle connector shall be a multi-piece assembly having single row of contacts in the
mating area which dividing into two signal segments (S1-S7, S8-S14) and a power segment (P1-
P15) which transit out to a in-line or stagger through hole pattern or surface mount pad. The
contact pattern in the mating area will have short and long terminals in a specific pattern that
results in a 0.5mm (0.020”) differential between contact points in the long and short terminals.
(This allows for first mate-last break capability – see respective product prints for location of short
and long terminals.) The receptacle hold down terminal has the board retention features that
secures the connector to the board in preparation for solder reflow (through-hole) or board
termination (press-fit or SMT).
A polarization peg (optional) on the bottom of the connector housing assures proper connector
orientation during board mounting. The receptacle through hole connector and press fit connector
are designed to terminate to board thickness of 1.57mm (0.062”), 2.36mm (0.093”) and 3.18mm
(0.125”). Visual examinations of connectors are to be done per EIA 364-18.
5.4.1 Mating. The connectors shall be capable of mating and unmating manually without
the use of special tools.
5.4.2 Workmanship. Connectors shall be uniform in quality and shall be free from burrs,
scratches, cracks, voids, chips, blisters, pin holes, sharp edges, and other defects
that will adversely affect product’s life or serviceability.
6 ELECTRICAL CHARACTERISTIC
6.1 Current Rating. The temperature rise above ambient shall not exceed 30°C at any point in the system
when contact positions specified are powered at the power levels specified herein:
a) Ambient Conditions : still air at 25°C
b) Current Rating : 1.5A min per contact, continuous
c) Preparation : (i) Mount the connector to a test PCB.
(ii) Wire power pins P1, P2, P8 and P9 in parallel for power.
(iii) Wire ground pins P4, P5, P6, P10 and P12 in parallel for return.
(iv) Supply 6A in total of DC current to the power pins in parallel, returning from the
parallel ground pins (P4, P5, P6, P10 and P12).
(v) Measure and record the temperature after 96 hours (45 minutes ON and 15
minutes OFF per hour).
d) Reference : EIA-364-70A
6.2 Low Level Contact Resistance. The low-level contact resistance of a SAS receptacle connector
mated with a SAS plug connector shall not exceed a change of 15mΩ after environmental
exposure when measured in accordance with EIA 364-23. The maximum initial signal contact
resistance is 30mΩ shall not be exceeded after environmental exposure when measured in
accordance with EIA 364-23. The following details shall apply:
