M8 Splitter Cable A-Code 4 Pin for CAN / RS485 Motor Communication System

M8 Splitter Cable is an industrial communication drop cable designed for CAN bus and RS485 expansion in distributed motor control systems.

Featuring an M8 A-Code 4 Pin Male to Female main cable with a drop cable connection, this splitter enables multiple motors or field devices to be connected to a single communication bus.

This cable is specially designed for integrated stepper servo motors, integrated lead screw stepper servo motors, integrated brushless motors, and integrated torque servo motors with bus control functions. By using an M8 splitter structure, multiple motor nodes can share the same CAN or RS485 communication network, reducing wiring complexity and improving system scalability.

CAN / RS485 Communication Extension Design

In CAN and RS485 communication systems, multiple devices can share a common communication bus. The M8 Splitter Cable enables additional motor nodes to be connected without requiring separate communication cables running back to the controller.

Its splitter design simplifies field wiring, reduces cable requirements, and allows multiple motors to communicate over the same bus, improving installation efficiency and system expansion flexibility in industrial automation applications.

Applications

◆ Integrated Stepper Servo Motors

Designed for integrated stepper servo motors using CAN Bus or RS485 communication. The M8 splitter connects multiple motor nodes to a shared communication bus, reducing individual cable runs and simplifying multi-axis motion control system expansion.

◆ Integrated Lead Screw Stepper Servo Motors

Suitable for integrated lead screw stepper servo motors in precision positioning, linear motion platforms and automated actuators. The drop connection allows multiple motors to share a communication line, supporting compact wiring layouts.

Product FAQ

What Is an M8 CAN Bus / RS485 Splitter Cable ?

An M8 CAN Bus / RS485 splitter cable is an industrial communication assembly featuring an M8 A-coded 4-pin male-to-female main cable with a drop connection. It connects compatible motors and field devices to a shared CAN Bus or RS485 network.

Why Use an M8 Splitter Cable in Multi-Motor Systems ?

In multi-motor systems, individual wiring requires separate communication cables running back to the controller. The M8 splitter allows motors to share a common bus, reducing cable requirements, simplifying installation and supporting future node expansion.

Can Unlimited Motor Nodes Be Added Using M8 Splitter Cables ?

No. The maximum number of motor nodes depends on the communication protocol, controller capability, data rate, bus length and drop cable length. Network topology and termination requirements must be followed to maintain reliable communication.

Can the Splitter Cable Length and Pinout Be Customized ?

Yes. Premier Cable offers customized main cable lengths, drop cable lengths, M8 connector configurations, conductor specifications, shielding structures and pin assignments, with OEM sample development and bulk production support.
