M12 circular connector

Technical Specifications

M12 Panel-Mount Male Receptacle | B2B OEM/Wholesale Supply

Product Overview

The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água is an M12 circular connector in a male panel-mount (bulkhead) configuration, offered with 3, 4, 5, or 6 contacts and fitted with a sealing O-ring for environmental protection when mounted through a panel or enclosure wall. As an industrial connector manufacturer, we produce this M12 connector as the panel-side half of an M12 sensor/actuator connection, mating with a field-attachable or over-molded M12 cable connector. For M12 circular connector buyers—including sensor manufacturers, machine builders, enclosure fabricators, and maintenance distributors—this product is a panel feedthrough component, not a complete cable assembly.

M12 Thread & Panel Mount Form

The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água uses an M12×1 metric thread, with a hex nut and threaded body designed to be mounted through a drilled panel cutout from inside or outside the enclosure. The male contacts face outward (or inward, depending on variant) to mate with the corresponding M12 cable connector. As an M12 panel mount supplier, we produce the holder to standard M12 thread dimensions so it mates with common M12 cable connectors from compatible manufacturers. For M12 bulkhead connector buyers, this panel-mount form factor is the standard way to bring sensor or signal circuits through a machine enclosure or sensor housing.

3 / 4 / 5 / 6 Pin Configurations

The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água is offered in four common contact counts: 3-pin, 4-pin, 5-pin, and 6-pin, covering the most common sensor and actuator circuits. Pin layout follows the common M12 A-coded contact arrangement (where applicable), but pin assignments can vary by device manufacturer. As an M12 3 pin manufacturer for the simplest two-wire sensor circuits, an M12 4 pin supplier for common 4-wire sensor circuits, and an M12 5 pin / M12 6 pin supplier for additional signal circuits, we recommend that buyers confirm the exact pinout against their sensor or device specification before volume ordering. For M12 sensor connector buyers, choosing the correct pin count avoids wasting spare contacts or forcing a multi-pin holder into a simple two-wire application.

Waterproof O-Ring & Sealing

The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água includes an O-ring that compresses between the holder flange and the panel when the hex nut is tightened, providing an environmental seal around the panel cutout. When mated with a matching M12 cable connector and correctly installed, the assembly reaches an IP67-rated sealing against dust and temporary water immersion. As an M12 waterproof connector manufacturer, we note that the O-ring seals the panel penetration, not the mated connector itself; both the panel O-ring and the mated connector seal must be correctly installed for the full IP rating. For M12 male receptacle buyers, we recommend confirming the panel cutout size and the O-ring compatibility with the enclosure material before drilling.

Termination & Wiring

The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água is typically available with solder cups or screw-terminal contacts on the rear (inside-panel) side, allowing wires to be terminated inside the enclosure. The holder is designed to be mounted through the panel, with the wiring side accessible inside the enclosure. As an M12 panel feedthrough manufacturer, we recommend that installers route and strain-relieve internal wiring so that no pulling force is applied directly to the solder cups or screw terminals. For M12 chassis connector buyers, this rear-side termination approach is standard for machine-build and panel-build applications where the connection between the external cable and the internal control circuit must be sealed.

Applications

The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água is used across a range of industrial automation scenarios: as the panel-side connection on proximity sensors, photoelectric sensors, and limit switches; as a signal feedthrough on machine enclosures and control boxes; as a sensor port on junction boxes and valve manifolds; and as a replacement panel connector on existing machines. As an industrial M12 connector supplier, we serve sensor manufacturers, machine builders, enclosure fabricators, and maintenance depots. For M12 receptacle buyers, this product is a standard BOM item wherever M12 sensor cables must enter an enclosure.

OEM / Customization & Wholesale

We offer M12 connector OEM and private-label services for sensor brands, machine builders, and enclosure manufacturers that want a configuration-specific panel holder. The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água supports customization of pin count (3/4/5/6), termination style (solder or screw), housing material, and bulk or retail packaging. As an M12 connector supplier manufacturer, we support order quantities from sample pieces for engineering validation to bulk production runs for sensor OEMs. We provide sample units for buyers to test panel cutout fit, O-ring sealing, and mating feel with their existing M12 cable connectors.

Frequently Asked Questions

Q: Is this the panel mount or the cable plug? The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água is the male panel-mount receptacle—the half that screws through a panel or enclosure wall. The cable-side M12 connector (field-attachable or over-molded) is sold separately. Please specify whether you need the panel holder, the cable connector, or both when ordering.

Q: Does it include the O-ring and hex nut? Yes. The Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água includes the sealing O-ring and mounting hardware required for panel installation. The panel cutout size should be confirmed against the product drawing before drilling.

Q: What IP rating does it achieve? When correctly installed through a panel and mated with a matching M12 cable connector, the Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água assembly reaches IP67. The O-ring seals the panel penetration; the mated connector seal is provided by the cable connector half. An incorrectly sized panel cutout or missing O-ring will reduce the sealing performance.

Q: Can I solder wires directly inside? Yes. The rear side of the Conector macho circular M12 de 3 a 6 pinos com anel de vedação à prova d'água offers solder cups or screw terminals (per variant) for internal wiring. We recommend using the appropriate wire gauge for the contact rating and strain-relieving internal wiring so that no mechanical load rests on the solder joints.
