Two Part P.C. Connectors

The series 801 and 801CX two part printed circuit board connector system utilizes a 1.27mm(0.05in.) staggered pitch with 2.54mm(0.1in.) between rows has been designed to satisfy the latest requirements of MIL-C-55302/140 thru 155. The series 801 l.f. connectors are available in 9 sizes from 17 to 96 ways. The series 801CX mixed layout styles provide the addition of 3 to 6 cavities capable of of accepting either coaxial or high power inserts in 10 sizes from 5 + 3 to 53 + 3 combinations.

MOULD SIZES

A wide choice of mould sizes are available:

l.f. - 17, 29, 33, 41, 53, 65, 72, 84, and 96.

mixed layout - 5+3, 5+6, 0+7, 17+3, 17+6, 29+3, 29+6, 41+3, 41+6, 53+3

TERMINATION STYLES (low frequency)

Available for both male and female covering p.c.b.s of 1.6, 2.4 and 3.2mm thickness there is a choice of straight and 90°p.c., solder for wire, crimp (22-26 AWG) and wire wrapping. High power contacts are available with solder bucket, straight and 90°p.c.

TERMINATION STYLES (high frequency)

Available for both male and female, they are suitable for twisted pairs, straight and 90° flexible coaxial cable (RG178), straight and 90° semi rigid cable (RG405-UT85) and straight and 90°p.c. Preserved impedance is maintained with flexible and semi rigid coaxial types (50ohm) with a reflection coefficient of 0.13 max. up to 2GHz.

ACCESSORIES

Covers suitable for round or flat cable with side or top entry are available for sizes from 17 up to 65 way (or their equivalent mixed layout).

Where male 90° p.c. connectors are mounted to "daughter boards" a pin shroud can be fitted to all mould sizes to reduce the risk of accidental pin damage.

A full range of tools for crimping and contact removal are available.

GUIDES

A comprehensive range of guides is provided. These may be polarized to provide 36 positions or may be unpolarized. There is a choice of standard, jacketing and ¼ turn locking.
