1. INTRODUCTION
This specification covers requirements for application of AMPLIMITE HD–20 Series 454 and 545 Right–Angle
Rear Load Metal Shell Connectors designed for Printed Circuit (PC) Boards. The series designator is the
dimension from the center of the first row of solder tines to the back surface of the mounting flange.
These connectors are made in five shell sizes: Size 1 has 9 positions; size 2 has 15 positions; size 3 has 25
positions; size 4 has 37 positions; and size 5 has 50 positions. Connector receptacles are available in 9, 15,
25, 37, and 50 positions in Series 454 and 545. Connector plugs are available in 9, 15, 25, and 37 positions in
Series 454 and 545, and 50 positions in Series 545. They have square solder tines. Plugs are available with or
without grounding indents. The plugs contain pin contacts and the receptacles contain socket contacts.
Standard connectors are available with or without No. 4–40 screws. They can be made available with
screwlocks in the support bracket. These connectors can be mated with free hanging cable connectors
designed for insulation displacement contacts (IDC) using ribbon cable and crimp, snap–in contacts using
discrete wire.
Figure 1 shows the product components and terms of their features. These terms will be referred to throughout
this specification. Use these terms when corresponding with Tyco Electronics Representatives to facilitate
assistance. The illustrations represent a typical connector plug and receptacle with available mounting options.
In actual application, the plug and receptacle connectors may have screwlocks or 4–40 screws in the mounting
flanges.

2.2. Customer Assistance
Product Base Part Number 745114 and Product Code 4934 are representative of AMPLIMITE HD–20 Series
Right–Angle Rear Load Metal Shell PC Board Connectors. Use of these numbers will identify the product line
and expedite your inquiries through a service network established to help you obtain product and tooling
information. Such information can be obtained through a local Tyco Electronics Representative (Field Service
Engineering, Field Applications Engineer, etc.) or, after purchase, by calling the Tooling Assistance Center or
FAX/PRODUCT INFO number at the bottom of page 1.
2.3. Drawings
Customer Drawings for each product part number are available from the service network. The information
contained in Customer Drawings takes priority if there is a conflict with this specification or with any technical
documentation supplied by Tyco Electronics.
2.4. Product Specifications
Product Specification 108–40025 provides product performance and test information.
2.5. Soldering Information
Manual 402–40 can be used as a guide to soldering. This manual provides information on various flux types
and characteristics with the commercial designation and flux removal procedures. A checklist is included in the
manual as a guide for information on soldering problems.
3. REQUIREMENTS
3.1. Storage
A. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in connectors.
B. Shelf Life
The connectors should remain in the shipping containers until ready for use to prevent damage. The
products 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 connectors near any chemicals listed below, as they may cause stress corrosion cracking in
the components.
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 instead of brass if
available.
3.2. Connector Shell Sizes
There are five industry standard shell sizes available for these connectors. A composite of the five receptacle
sizes with the overall dimension for each is provided in Figure 2.

3.3. Panel Mounting Cutout
Panel mounting is optional for AMPLIMITE Right–Angle Rear Load Metal Shell PC Board Connectors. For pc
board receptacles, it will provide additional support for the solder joints during mating and unmating of
connectors. The pc board receptacles can ONLY be rear mounted. Either front or rear mounting is acceptable
for the mating cable connector. The connector mounting bracket flanges have 4–40 internal threads that will
accept screwlocks or panel mounting screws. Hardware attached to the connector bracket flange shall be
tightened to 0.45 N
D
m [4 in.–lb] maximum. See Figure 3 for panel cutout dimensions.
Screwlocks are designed to secure a connector to a panel 1.58 [.062] thick. They can be used with thinner
panels; however, washers are recommended to make up the thickness difference and provide a bottoming
surface for the mating connector flange. Screwlocks should be tightened to a torque of 0.45 N
D
m [4 in.–lb]
maximum. The 4–40 internal threads in the screwlocks will accept commercially available 4–40 threaded
screws and jackscrews.

3.4. Mating Dimensions
114–40013
The dimensions shown in Figure 4 must be considered when determining method of mounting and thickness of
the panel when connectors are to be panel–mounted. This dimension ensures full mating of connectors.
6.73+0.38 [.265+.015] For 9– and 15–Position
6.50+0.38 [.256+.015] For 25–, 37–, and 50–Position

3.5. Connector Spacing
Care must be used to avoid interference between adjacent connectors and/or other components. The
dimension is dependent on variable hardware used and the clearance required for mating connectors. The
information provided in Figure 5 is to ensure proper mating for manual placement of connectors.
