The flange mount design allows the socket to be permanently fixed to a control panel, junction box, or equipment enclosure — creating a standardized, IP67-rated connection point for field device cables. A-code is the most common M12 coding for general-purpose sensor and actuator connections (4-pin and 5-pin) and Ethernet (8-pin). The threaded coupling nut on the mating cable connector provides vibration-resistant locking.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e IEC 61076-2-101 (M12 circular connector)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoding:\u003c\/strong\u003e A-code (general sensor\/actuator and Ethernet)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Configurations:\u003c\/strong\u003e 4, 5, 8 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 (4\/5-pin); 0.5A per contact (8-pin Ethernet)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 30V DC (signal); 60V AC (power)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e Panel back mount with flange (M12 thread through panel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling:\u003c\/strong\u003e M12 threaded coupling nut on mating connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eM12 A-Code Pin Assignment Standards\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4-pin A-code (standard sensor):\u003c\/strong\u003e Pin 1 = +V supply (brown), Pin 2 = Output A (white), Pin 3 = GND (blue), Pin 4 = Output B (black) — IEC 60947-5-2 standard for 4-wire PNP\/NPN sensors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5-pin A-code (standard actuator):\u003c\/strong\u003e Pin 1 = +V supply, Pin 2 = Output A, Pin 3 = GND, Pin 4 = Output B, Pin 5 = PE (protective earth)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e8-pin A-code (Ethernet):\u003c\/strong\u003e Standard Ethernet T568B wiring — used for 100BASE-TX and 1000BASE-T industrial Ethernet (PROFINET, EtherNet\/IP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eM12 Coding Guide — A vs B vs D vs X\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eA-code (this product):\u003c\/strong\u003e General sensor\/actuator (4\/5-pin) and Ethernet (8-pin).

The flange overlaps the hole and is secured by a nut from the rear (or by screws through the flange, depending on the specific socket design). Panel thickness: typically 1–6mm. For thicker panels, use a socket with a longer threaded body or countersink the panel hole.\u003c\/p\u003e\n\n\u003ch4\u003eWhat is the difference between front mount and back mount M12 sockets?\u003c\/h4\u003e\n\u003cp\u003eFront mount: the socket body is inserted from the front of the panel; the nut tightens from the rear. The connector face is flush with or slightly proud of the panel front. Back mount (this product): the socket body is inserted from the rear of the panel; the flange sits against the rear panel surface. The connector face protrudes through the panel to the front. Back mount provides a cleaner front panel appearance and is preferred for control panels where aesthetics matter.\u003c\/p\u003e\n\n\u003ch4\u003eCan I use A-code 8-pin M12 sockets for PROFINET?\u003c\/h4\u003e\n\u003cp\u003eYes. PROFINET uses standard Ethernet (100BASE-TX or 1000BASE-T) over M12 A-code 8-pin connectors. The wiring follows standard Ethernet T568B color coding. Verify that the cable and connector are rated for the required Ethernet speed — Cat5e cable and connectors for 100BASE-TX; Cat6 or better for 1000BASE-T.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFactory automation:\u003c\/strong\u003e Sensor and actuator connection points on control panels and junction boxes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial Ethernet:\u003c\/strong\u003e PROFINET, EtherNet\/IP panel connection points (8-pin A-code)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine building:\u003c\/strong\u003e Standardized sensor connection interfaces on machine panels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFood \u0026amp; beverage:\u003c\/strong\u003e Washdown-rated sensor connection points in food processing equipment panels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRobotics:\u003c\/strong\u003e End-of-arm tooling connection interfaces on robot cell panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003eM12 A-code panel back mount flange socket (pin count as selected).
