The M8 thread (8mm diameter) provides a smaller panel footprint than M12 — ideal for high-density sensor connection panels where space is limited. The flange mount design permanently fixes the socket to the panel, creating a standardized IP67-rated connection point for field sensor cables. A-type coding is the standard for general-purpose sensor and actuator connections.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e IEC 61076-2-104 (M8 circular connector)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoding:\u003c\/strong\u003e A-type (general sensor\/actuator)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Configurations:\u003c\/strong\u003e 3, 4, 5 pin (select above)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating:\u003c\/strong\u003e IP67 (mated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 4A per contact (3\/4-pin); 2A per contact (5-pin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 30V DC (signal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e Panel back mount with flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Hole:\u003c\/strong\u003e 8mm diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eM8 vs M12 Panel Sockets — When to Use M8\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eM8 (this product):\u003c\/strong\u003e 8mm thread, 4A per contact, up to 5 pins.

The flange overlaps the hole and is secured by a nut from the rear (or screws through the flange). Panel thickness: typically 1–4mm. The smaller panel hole compared to M12 (12mm) allows higher connection density on compact panels.\u003c\/p\u003e\n\n\u003ch4\u003eAre M8 and M12 connectors interchangeable?\u003c\/h4\u003e\n\u003cp\u003eNo. M8 (8mm thread) and M12 (12mm thread) connectors are different sizes and are not interchangeable. M8 cable connectors will not mate with M12 panel sockets, and vice versa. Always verify the connector size before ordering replacement sockets or cable connectors.\u003c\/p\u003e\n\n\u003ch4\u003eCan I use M8 connectors for 24V DC sensor applications?\u003c\/h4\u003e\n\u003cp\u003eYes. The 30V DC rating covers standard 24V DC industrial sensor supply voltages. The 4A per contact rating (3\/4-pin) supports most 24V proximity sensor and photoelectric sensor current requirements (typical sensor current: 100–200mA). For actuators drawing more than 4A, use M12 connectors.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-density sensor panels:\u003c\/strong\u003e Compact control panels with many sensor connection points\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFactory automation:\u003c\/strong\u003e Proximity sensor and photoelectric sensor panel connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine building:\u003c\/strong\u003e Compact actuator and valve connections in space-constrained machines\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRobotics:\u003c\/strong\u003e End-of-arm tooling sensor connections where M12 is too large\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFood \u0026amp; beverage:\u003c\/strong\u003e Washdown-rated sensor panel connections in compact equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003eM8 A-type panel back mount flange socket (pin count as selected).
