What is an M8 Connector?
Definition
M8 Connector is a type of metric circular connector with an 8mm locking thread interface. It can provide reliable and efficient connections in limited space. It exists in many industrial automation systems, providing reliable connections for power and signal transmission.
Standard
IEC 61076-2-104 is the standard for M8 connectors. It specifies m8 connectors’ dimensions, pin configuration, and environmental resistance. UL certification focuses on safeguards such as fire resistance, guaranteeing that the connector meets specific safety criteria.
Main Features
M8 connectors have various features:
Compact Size
M8 connectors are compact and ideal for applications with limited space.
Versatility
M8 connectors offer a wide variety of mounting options, including panel mount, cable mount, and PCB mount. They also provide different connection types such as screw, crimp, and solder. Additionally, the M8 connector comes in various pin configurations, including 3-pin, 4-pin, 5-pin, 6-pin, 8-pin, and more. This versatility allows M8 connectors to be built to meet a wide range of application needs.
Durability
The design of M8 connectors incorporates strong materials that provide resistance to shock, vibration, and severe temperature fluctuations. As a result, they are well-suited for challenging industrial environments.
Quick and Easy Connection
The design of the M8 connector includes a threaded coupling, which streamlines the connection and disconnection process. This simple replaceability results in lower maintenance costs and improved efficiency in time management.

Types of M8 Connector
M8 connectors are available in multiple configurations to accommodate a diverse array of applications. There are eight distinct types based on their mounting types and the number of pins.
By Mounting Types
Cable Type
M8 cable connectors are designed for direct attachment to the terminal end of a cable. There are two types of cable connections available: screw-joint and solder.
Panel Mount
M8 panel mount connectors are designed to be securely attached to a board or chassis. There is only one type of panel mount available: the Bulkhead. These connectors can be further categorized into front-mount and rear-mount connectors.
PCB Mount
M8 PCB mount connectors are specifically constructed for direct assembly onto printed circuit boards (PCBs). They are available solely in the Through Hole type configuration.
By Pin Configuration
There are 5 typical types of the M8 connector:
Technical Specifications
The technical specifications of the M8 connector encompass electrical, mechanical, and environmental attributes. These specifications align with the functional and performance criteria required for the connector’s application. Below are five main specifications.
Voltage Rating
The M8 connectors operate at voltage levels of 30V and 60V. The rated voltage is associated with the number of pins in the connector. Connectors have 3, 4, 5, or 6 pins are rated for 60V, while 8-pin connectors have a rated voltage of 30V.
Current Rating
The current rating signifies the highest level of current that the M8 connector can securely support. These connectors are classified into three current levels: 1.5A for 8-pin connectors, 2A for 6-pin connectors, and 4A for 3-pin, 4-pin, and 5-pin connectors.
Mating Cycles
Mating cycles indicate the number of times a connector can be connected and disconnected while maintaining its operational integrity. Typically, M8 connectors can withstand more than 500 mating cycles.
Wire Gauge
M8 connectors are generally configured with wire gauges of 22 AWG and 26 AWG.
Operating Temperature
The operational temperature range for the M8 connector extends from -25°C to +100°C.
Applications of M8 Connector
Due to their compact form and trustworthy connectivity, M8 circular connectors have found significant applications in diverse industries. Here are some common applications:
Industrial Automation
M8 3-pin and 4-pin connectors are extensively utilized in the field of industrial automation. Their main function is to facilitate the establishment of connections among sensors, switches, actuators, PLCs, I/O boxes, and various other parts integral to industrial machinery.
Robotic Systems
The M8 connectors satisfy the spatial constraints and anti-interference needs of robotic systems. As a result, they can effectively link robot joints, sensors, controllers, and other essential components.
Medical Equipment
M8 connectors have the characteristics of anti-interference. So they are suitable for connecting medical equipment, like electrocardiographs and blood pressure monitors.
Agricultural Automation
M8 connectors can connect sensors and control devices in agricultural machinery and are resistant to harsh conditions.
Applications of M8 Connector
How to Choose the Right M8 Connector
Selecting the appropriate M8 connector requires careful consideration of several essential factors to ensure it aligns with the specific requirements.
Application Analysis: It is essential to comprehend the specific applications for which the M8 connector is utilized, while also taking into account the electrical, mechanical, and environmental conditions pertinent to your products.
Number of Pins: Select the appropriate number of pins based on the application requirements, which may include options such as 3-pin, 4-pin, 5-pin, 6-pin, or 8-pin.
Cable Type and Size: It is essential to take into account the voltage and current specifications. In environments with electromagnetic interference, it is advisable to select shielded cables. For applications that require higher current, it is essential to utilize thicker gauge wire to maintain compatibility with the M8 connector size.
Environmental Factors: The environment significantly influences both performance and durability, taking into account factors such as temperature, humidity, and exposure to chemicals or moisture. M8 connector is rated IP67 and IP68, with the IP68 rating providing superior protection against water and dust compared to the IP67 rating.
Shell Material: The shell material of the M8 connector commonly utilized is standard nickel-plated brass, which is both economical and widely available. For environments with high corrosive conditions, stainless steel is the preferred choice due to its superior resistance.
