ITT Cannon CA Series MIL-DTL-5015 Connector Selection Guide

ITT Cannon CA Series connectors are rugged metal circular connectors derived from MIL-C-5015 and MIL-DTL-5015-style interfaces. The range supports power, control and signal connections in industrial machinery, transportation equipment, defense systems, motors, drives and other equipment exposed to vibration, moisture and mechanical stress.

The CA Threaded family uses screw coupling and includes wall-mount receptacles, cable receptacles, box-mount receptacles, straight plugs and right-angle plugs. Depending on the configuration, the series supports 2 to 65 signal contacts, wire sizes from 26 AWG to 0 AWG and current ratings up to 245 A. Actual electrical and environmental ratings depend on the selected insert arrangement, contact size, service class and termination.

ITT Cannon CA Series Key Specifications

The maximum values shown above apply only to selected configurations. Do not use the family maximum current, wire size or contact count as the rating of an individual connector.

CA3100, CA3101, CA3102, CA3106 and CA3108 Differences

The four-digit connector-style code identifies the basic shell and mounting configuration.

CA3106 and CA3108 plugs are normally selected to mate with compatible CA3100, CA3101 or CA3102 receptacles. Compatibility requires the same shell size, insert arrangement and keying, together with complementary pin and socket contacts.

CA3100 Wall-Mount Receptacle

CA3100 is used where the receptacle must be permanently mounted to an equipment wall or panel. It is suitable for control cabinets, motors, industrial machines and vehicle-mounted equipment.

Selection points include:

• Front or rear panel installation

• Panel cutout and mounting-hole dimensions

• Pin or socket contacts

• Insert arrangement

• Environmental service class

• Rear cable or wiring accessories

CA3101 Cable-Mount Receptacle

CA3101 is a free-hanging receptacle installed on a cable rather than directly on an equipment panel. It is useful for cable-to-cable connections and extension harnesses.

A CA3101 receptacle may mate with a compatible CA3106 straight plug or CA3108 right-angle plug, provided the insert arrangement, contact gender and orientation match.

CA3102 Box-Mount Receptacle

CA3102 is a flange-mounted receptacle commonly installed on equipment housings, junction boxes and control panels. It normally provides a fixed interface for a cable plug.

CA3102 is frequently paired with:

• CA3106 straight plugs

• CA3108 right-angle plugs

The receptacle and plug must have matching shell size and insert arrangement. One side must use pin contacts and the other side must use socket contacts.

CA3106 Straight Plug

CA3106 is one of the most widely searched ITT Cannon CA connector styles. It provides a straight cable exit and threaded coupling.

CA3106 is suitable when:

• There is sufficient space behind the cable

• A conventional straight harness exit is required

• The connector must mate with a panel or cable receptacle

• Power and signal contacts are combined in one circular interface

CA3108 Right-Angle Plug

CA3108 uses a 90-degree cable exit. It is selected where enclosure depth is limited or where the cable must run parallel to the panel.

CA3108 can provide a more practical installation than CA3106 in compact control boxes, vehicle systems and equipment mounted close to a wall.

Common ITT Cannon CA Series Part Numbers

The manufacturer part number must be checked in full. Additional suffixes can change the contact termination, backshell, cable clamp, environmental construction, plating or other mechanical features.

CA Series vs CA-COM

CA-COM is a related industrial connector family intended for rugged industrial, transportation and medical applications. It is available in threaded and bayonet versions and includes nickel-plated shell options.

CA, CA-B and CA-COM part numbers must be treated as separate configurations until the manufacturer drawings confirm mating compatibility.

Can ITT Cannon CA Replace MS3100–MS3108 Connectors?

ITT Cannon CA Series connectors are frequently evaluated as alternatives to MS3100, MS3101, MS3102, MS3106 and MS3108 connectors.

The general style relationships are:

A matching style number does not guarantee a drop-in replacement. Check:

• Applicable qualification

• Coupling thread

• Shell size

• Insert arrangement

• Pin or socket contacts

• Keying and insert rotation

• Service class

• Contact termination

• Shell plating

• Panel dimensions

• Backshell compatibility

• Environmental requirements

If the project requires a qualified MS or MIL part number, a commercial CA number should not be substituted without customer or engineering approval.

Main Applications

ITT Cannon CA Series connectors are used in:

Industrial Machinery

CA connectors carry power and control signals between motors, drives, sensors, control cabinets and machine modules.

Transportation Equipment

The rugged metal shell and secure coupling support construction machinery, commercial vehicles, rail equipment and other vibration-prone systems.

Defense Systems

MIL-DTL-5015-style interfaces remain common in ground vehicles, communication equipment, test systems and legacy military platforms.

Motors and Drives

High-current insert arrangements can support motor power, braking, feedback and control connections.

Test and Measurement Equipment

CA connectors provide a removable interface for laboratory systems, field test equipment and industrial instruments.

Energy and Infrastructure

Applications include power-generation equipment, charging systems, industrial power distribution and outdoor control equipment.
