1. INTRODUCTION
This specification covers the requirements for application of AMPLIMITE .050 Series Cable End Insulation
Displacement Connectors (IDC) and Printed Circuit (PC) Board Connectors. The connectors offers
high–density “D” mating interfaces (keystone configuration) with 1.27 x 2.54 mm [.050 x .100 in.] contact
centerlines and 20 through 120 positions. They are compatible with SCSI–2, EIA RS–232, IPI, and HIPPI
standards. Connectors are available with metal shells over plastic housings for EMI/ESD–shielded applications,
and with all–plastic housings for unshielded applications.
IDC Cable End Connectors are available with pre–assembled or unassembled termination covers, and are
designed to terminate solid or 7–strand, 30 to 28 AWG wire with an insulation diameter range of
0.74 to 0.91 mm [.029 to .036 in.]. There are connectors designed for free–hanging applications and others for
panel mount applications. Free–hanging connectors will require the use of a backshell while panel mounted
connectors do not. See Figure 1.
NOTE
IDC Feed-Through Connectors are also available. See Application Specification 114-40049.
i
PC Board Connectors are available with solder–type or ACTION PIN* (solderless) contacts tails. Those with
solder–type contacts are available as straight and right–angle single configurations, or as right–angle stacked
configurations. Those with ACTION PIN (solderless) contacts are available in straight configurations only. The
connectors are available with cast or formed metal shells for shielded applications, and with all plastic housings
for unshielded applications. All of these connectors can be mounted through a panel. Cast metal shell
connectors are designed to be used with spring latches. Connectors with formed metal shells are designed for
screwlock and jackscrew applications. See Figure 1.
Accessories such as keying inserts, attaching hardware, and backshells are covered later in this specification.
When corresponding with Tyco Electronics Personnel, use the terminology provided in this specification to
facilitate your inquiry for information. Basic terms and features of the connectors are provided in Figure 1.

3. REQUIREMENTS
3.1. Storage
A. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the connectors.
B. Shelf Life
The connectors should remain in the shipping containers until ready for use to prevent deformation to the
contacts. The connectors should be used on a first in, first out basis to avoid storage contamination that
could adversely affect signal transmissions.
C. Chemical Exposure
Do not store the connectors near any chemical listed below as they may cause corrosion stress cracking
in the contacts.
Alkalies
Amines
NOTE
Ammonia
Carbonates
Citrates
Nitrites
Phosphates Citrates
Sulfur Nitrites
Sulfur Compounds
Tartrates
Where the above environmental conditions exist, phosphor-bronze contacts are recommended if available.

3.2. Contact Position Assignment
All AMPLIMITE .050 Series Connectors are marked to indicate contact position no. 1 only. Pins are numbered
in plug connectors from left to right, top row first. Sockets are numbered in receptacle connectors as a mirror
image of the plugs: right to left, top row first. Figure 2 shows typical assignments.
NOTE
The connectors in Figure 2 are viewed from the mating interface.

A. Cable Preparation
The strip length of jacketed cable will depend on the type of tooling used to terminate the wire. Refer to the
instructions packaged with the applicable tool for the proper cable jacket strip length. The only preparation
for ribbon cable is to cut it squarely.

NOTE
The braid length will vary depending on the backshell style, cable bundle size, and slack needed to assure strain relief
for all wires. Essential requirements are that the leading edge of the braid fold extends slightly beyond the beginning of
i
the shield taper and the trailing ends of the braid be trimmed so they do not extend beyond the backshell cable exit.
See Figure 4.
B. Lamination of Discrete Wires
Discrete wire cable may be laminated for mass termination by flattening the round bundle of wires and
applying a thin lamination over the ends of the wire as shown in Figure 4.
CAUTION
Do NOT cut individual wire insulation during stripping cable insulation, or when trimming braid shield and foil from
wrapping.
