What Is an XT30 2+2 Power and CAN Communication Cable ?

XT30 2+2 is a four-contact connector configuration that combines power contacts and signal contacts within one connector housing.

It consists of:

Two larger contacts for power transmission.
Two smaller contacts for signal or communication transmission.

In this cable configuration, the two power contacts are assigned to Power+ and Power−, while the two signal contacts are assigned to CAN_H and CAN_L.

An XT30 2+2 Power and CAN Communication Cable is therefore a hybrid cable assembly that integrates DC power conductors and CAN differential communication conductors into one cable system.Power and communication signals do not share the same conductors. Instead, they use electrically independent wires and dedicated connector contacts to provide power and communication simultaneously.

Key Advantages of XT30 2+2 Power and CAN Cables

Integrated Power and Communication

Integrating two 18AWG power wires and one 24AWG CAN communication pair into one cable assembly provides both electrical power and data transmission.

Compared with using two separate cable connections, this solution helps reduce connector quantity and simplify internal harness management.

Compact Equipment Integration

XT30 2+2 combines power and signal contacts within one connector housing, making it suitable for compact control modules, robotic joints, and 3D printer toolheads.

This design reduces the space required for separate interfaces and provides greater flexibility in equipment layout.

Dedicated Conductors for Different Functions

The cable uses different conductor gauges and constructions for power and communication.

The 18AWG conductors provide electrical power, while the 24AWG twisted pair carries CAN_H and CAN_L differential signals. This keeps power and communication functions electrically separated.

Supports Modular Equipment Connections

XT30 2+2 is suitable for modular electronic equipment requiring independent power and CAN communication, including control boards, motor drivers, robotic actuators, and embedded control modules.

Different male/female configurations and cable lengths can be developed to support various equipment interconnections.

How to Select the Right XT30 2+2 Power and CAN Cable ?

1,Connector Type and Pin Assignment

Verify the XT30 2+2 male or female connector and the positions of the four contacts: Power+, Power−, CAN_H, and CAN_L. Different devices or brands may use different pin assignments, so always check the equipment interface drawings before purchasing.

2,Power Wire Gauge and Electrical Specifications

Confirm the power wire specification, such as 18AWG × 2C, and verify the operating voltage, rated current, and cable length according to equipment requirements. Actual current-carrying capacity also depends on conductor material, ambient temperature, cable construction, and connector ratings.

3,CAN Twisted Pair and Impedance Matching

Verify the CAN signal wire specification, such as 24AWG × 1P, and check whether it meets the project's 120Ω nominal characteristic impedance requirement. Proper impedance matching helps reduce signal reflections and maintain CAN communication quality. Note that 120Ω characteristic impedance does not mean the cable contains a built-in 120Ω termination resistor.

4,Cable Length and Construction

Select the appropriate cable length according to the installation distance between devices. Determine whether shielding, flexible conductors, abrasion-resistant jackets, or additional protection are required. For moving components such as robotic joints and 3D printer toolheads, consider continuous motion and repeated bending requirements.

5,Equipment Compatibility and Communication Requirements

Before connection, verify that the equipment genuinely supports the XT30 2+2 interface. Check the CAN communication speed, bus topology, termination configuration, and electrical interface requirements. Identical connector appearances do not guarantee compatible pin assignments or communication parameters. When necessary, provide the equipment model, interface drawings, and cable specifications for compatibility verification.

Product FAQ

Why Are 18AWG and 24AWG Used in the Same Cable ?

Power and communication circuits have different electrical requirements, so different wire gauges are commonly used in integrated power and communication cables.18AWG conductors have a larger cross-sectional area than 24AWG conductors and are suitable for carrying relatively higher power currents.

24AWG conductors can be used for CAN_H and CAN_L differential communication signals, meeting the requirements for conductor size, twisted-pair construction, and impedance characteristics.Combining these two wire gauges in one cable helps meet both power delivery and communication requirements without using the same conductor size for every circuit.

Why Does CAN Bus Use Two Signal Wires ?

CAN communication uses differential signaling, transmitting data through the voltage difference between CAN_H and CAN_L.

Compared with single-ended signaling, differential communication provides better rejection of external interference that affects both signal wires in a similar manner.

Twisting the two conductors helps external interference couple more evenly into both wires, allowing the receiver to reduce the impact of common-mode noise.Therefore, in XT30 2+2 cable designs, CAN_H and CAN_L are generally carried by a 24AWG twisted pair rather than two completely separate single-core wires.

Is XT30 2+2 the Same as a Standard XT30 Power Connector ?

Although their names are similar, the two connector types have different functions.

A standard XT30 is primarily designed for DC power connections and typically uses two power contacts for positive and negative connections.XT30 2+2 uses four contacts, with two larger contacts for power and two smaller contacts for signal or communication.

Therefore, XT30 2+2 can provide both power connections and additional signal transmission, including CAN_H and CAN_L.

When purchasing, the exact connector series must be verified. Mechanical appearance or the XT30 name alone does not guarantee interchangeability.

Can Premier Cable Customize XT30 2+2 Cable Lengths and Pin Assignments ?

Yes. Premier Cable can customize cable lengths, connector gender combinations, 18AWG power wires, 24AWG CAN twisted pairs, and pin assignments according to customer equipment requirements.
