Overview

The M8 connector series is our company's high-quality miniature circular connector product line for industrial automation and equipment manufacturing. Designed in strict compliance with IEC 61076-2-104, the series features a compact M8 threaded interface and offers A-coded and B-coded configurations across 3, 4, 5, 6, and 8-pin variants. The product line comprises three types: M8 pre-molded connectors (overmolded cable assemblies), M8 flange connectors (panel-mount), and M8 field-attachable connectors (on-site wireable), supporting male, female, straight, and right-angle termination, all rated to IP67. The series meets the reliable-connection requirements of sensors, actuators, fieldbus, and small automation devices across a wide range of applications.

With stable product quality, ample inventory, and a highly competitive pricing structure, the M8 connector series has become an ideal domestic-substitution choice for enterprises looking to significantly reduce procurement costs while maintaining product performance and reliability.

Core Advantages

Reliable Quality, Stable Performance

• High-quality metal shells and precision gold/tin-plated contacts deliver low contact resistance and stable signal transmission.
• The full series is IP67-rated, offering excellent water, dust, and vibration resistance for long-term stable operation in harsh industrial environments.
• A strict quality-control system spanning raw materials, manufacturing, and final inspection ensures batch-to-batch consistency.

Ample Inventory, Fast Delivery

• Standard specifications are kept in stock and available for rapid dispatch, effectively shortening project delivery cycles.
• A well-established warehousing and logistics system ensures timely supply for bulk orders, helping keep customers' production lines running continuously.

Price Advantage, Cost Reduction

• Leveraging a mature supply chain and scaled manufacturing, the series achieves a price level significantly lower than imported brands.
• While delivering equivalent quality and performance, it helps enterprises effectively reduce procurement costs — the ideal domestic alternative.

Product Types

M8 Pre-Molded Connectors

Overmolded-cable design with the connector and cable encapsulated and crimped as a single unit before shipment, available in standard cable lengths of 2M, 5M, and 10M, with A-coded and B-coded 3, 4, 5, 6, and 8-pin configurations. The pre-molded design eliminates on-site termination, enabling true plug-and-play, with stable and reliable protection — ideal for standardized mass production, bulk wiring, and long-term use scenarios demanding high reliability.

M8 Flange Connectors

Panel-mounted with front-lock and rear-lock options, available in A-coded and B-coded 3, 4, 5, 6, and 8-pin configurations. The flange design enables secure installation on equipment panels, control cabinets, and sensor housings, with reliable sealing and precise positioning — ideal for long-term fixed-interface wiring.

M8 Field-Attachable Connectors

Field-wireable design supporting solder-free screw/spring-cage or quick-crimp termination, available in male and female, straight and right-angle versions. Field-attachable connectors require no pre-crimped cable and can be wired flexibly on site, greatly improving installation efficiency and wiring flexibility — ideal for on-site custom-length, rapid replacement, or temporary wiring scenarios.

Application Scenarios

With their compact size, reliable protection, and standardized interface, M8 connectors are widely used across the following industries and scenarios:

Competitive Comparison in the Same Scenario

Taking the most common sensor/actuator connection scenario in industrial automation as an example, the table below compares Kronz M8 series against typical competitors (Tier-1 imported brands and generic domestic brands):

Conclusion: Our M8 connector series delivers performance and reliability on par with imported brands at a significantly lower price and with faster delivery, while also clearly outperforming generic domestic brands in quality consistency and specification completeness. It is the ideal domestic-substitution solution that balances quality, delivery, and cost.

M8 Flange Connector Positioning and Competitive Advantages

In scenarios requiring fixed interfaces and long-term stable wiring (such as equipment panels, control cabinets, and sensor housing integration), the M8 flange connector offers distinct advantages over pre-molded cable assemblies and field-attachable connectors:

Core advantages of the M8 flange connector: panel mounting provides precise positioning and reliable mechanical fixation, with front-lock and rear-lock options to suit different installation spaces; IP67 protection and a panel seal ring ensure long-term through-panel waterproof and dust-proof performance; a complete range of 3, 4, 5, 6, and 8-pin A/B-coded configurations makes it the ideal choice for long-term fixed interfaces on the equipment side.

M8 Pre-Molded Connector Positioning and Competitive Advantages

In scenarios requiring plug-and-play and standardized bulk wiring (such as standardized mass production, bulk equipment shipment, and long-term use demanding high reliability), the M8 pre-molded connector offers distinct advantages over flange connectors and field-attachable connectors:

Core advantages of the M8 pre-molded connector: the connector and cable are molded as a single unit at the factory, with overmolding plus full inspection ensuring termination consistency and long-term IP67 protection stability; complete 2M/5M/10M standard lengths and A/B-coded 3–8 pin configurations enable plug-and-play, dramatically improving bulk deployment efficiency while eliminating quality risks from on-site wiring errors — the ideal choice for standardized mass production and bulk equipment shipment.

M8 Field-Attachable Connector Positioning and Competitive Advantages

In scenarios requiring on-site wiring and rapid deployment (such as production-line retrofits, equipment maintenance, and temporary wiring), the M8 field-attachable connector offers distinct advantages over flange connectors and pre-molded cable assemblies:

Core advantages of the M8 field-attachable connector: quick on-site wiring without pre-crimped cables, dramatically shortening deployment and maintenance time; complete male/female and straight/right-angle range to suit tight spaces and various cable-exit directions; IP67 protection and gold-plated contacts ensure signal stability in field conditions — the ideal choice for flexible industrial on-site wiring.
