M8 3-6 Pin Waterproof Male Connector

Technical Specifications

M8 Compact Sensor Plug | B2B OEM/Wholesale Supply

Product Overview

The M8 3-6ピン防水オス型コネクタ（2ピース） is a compact M8 circular connector in a male cable-side form factor, offered with 3, 4, 5, or 6 contacts and built for field assembly onto a cable. As an industrial connector manufacturer, we produce this M8 connector for compact sensor and actuator applications where an M12 connector would be too large. For M8 circular connector buyers—including miniature sensor manufacturers, machine builders, and maintenance distributors—this product is a connector component, not a complete cable or sensor.

M8 Thread & Compact Form Factor

The M8 3-6ピン防水オス型コネクタ（2ピース） uses an M8×1 metric thread, a smaller circular connector form factor commonly chosen for space-constrained sensor and signal connections. The male plug screws onto a matching M8 female receptacle or cable connector, with a small coupling ring that provides a secure, vibration-resistant connection in tight spaces. As an M8 male connector supplier, we produce the plug to M8 thread dimensions so it mates with standard M8 female connectors and panel receptacles from compatible manufacturers. For M8 sensor connector buyers, the M8 form factor is the standard choice where small proximity sensors, photoelectric sensors, or signal transmitters require a compact, sealed circular connection.

Two-Piece Construction

The M8 3-6ピン防水オス型コネクタ（2ピース） is supplied as a two-piece assembly: the main plug body and a separate coupling nut / rear gland that slides over the cable before the plug body is assembled. This design allows field termination by sliding the rear piece over the cable, wiring the contacts inside the plug body, and then tightening the rear gland onto the body to strain-relieve the cable and compress the seal. As an M8 cable connector manufacturer, we recommend that installers thread the rear piece onto the cable before starting termination—a common installation mistake is wiring the plug body first and then discovering the coupling nut cannot pass over the assembled contacts. For M8 field-wireable buyers, this two-piece design is the standard field-assembly format for M8 connectors.

3 / 4 / 5 / 6 Pin Configurations

The M8 3-6ピン防水オス型コネクタ（2ピース） is offered in four common contact counts: 3-pin, 4-pin, 5-pin, and 6-pin, covering the most common compact sensor and signal circuits. As an M8 3 pin supplier for simple two-wire or three-wire sensor circuits, an M8 4 pin supplier for common 4-wire sensor connections, and an M8 5 pin / M8 6 pin supplier for additional signal circuits, we recommend that buyers select the pin count based on the actual number of circuits required by the device. Pin assignments follow common M8 layouts but can vary by sensor manufacturer, so we recommend confirming pinout against the device specification before volume ordering.

Waterproof Sealing

The M8 3-6ピン防水オス型コネクタ（2ピース） is built with an internal cable seal and a mating-face seal that, when correctly assembled and mated with a matching M8 female connector, provides IP67-rated sealing against dust and temporary water immersion. As an M8 waterproof connector manufacturer, we note that the IP rating depends on correct assembly: the cable must fit the included gland diameter range, the rear gland must be fully tightened, and the coupling ring must be fully mated. An incorrectly sized cable or a loosely assembled gland will reduce sealing performance. For M8 male plug buyers, we recommend confirming the cable outer diameter against the gland range before ordering.

Termination & Field Assembly

The M8 3-6ピン防水オス型コネクタ（2ピース） is designed for field assembly, with solder contacts or screw-terminal contacts depending on the variant. The connector can be terminated on site without specialized tooling beyond a screwdriver (screw versions) or soldering iron (solder versions). As an M8 plug manufacturer, we recommend that installers follow the contact pinout, keep wire strands contained under the screw terminals, and verify continuity before energizing the circuit. For compact circular connector buyers, this field-assembly design allows on-site cable length customization, which is the main advantage over pre-molded cables.

Applications

The M8 3-6ピン防水オス型コネクタ（2ピース） is used across a range of compact industrial applications: small proximity and photoelectric sensors, miniature limit switches, small actuators, signal transmitters, and compact field I/O modules where M12 is over-sized. As an M8 sensor plug supplier, we serve miniature sensor manufacturers, machine builders, system integrators, and maintenance depots. For industrial M8 connector buyers, this product is a standard BOM item on compact sensor circuits where space and sealing are both required.

OEM / Customization & Wholesale

We offer M8 connector OEM and private-label services for sensor brands, machine builders, and automation distributors that want a configuration-specific compact connector. The M8 3-6ピン防水オス型コネクタ（2ピース） supports customization of pin count (3/4/5/6), termination style (solder or screw), cable gland diameter range, housing material, and bulk packaging. As an M8 connector supplier manufacturer, we support order quantities from sample pieces for engineering validation to bulk production runs for miniature sensor OEMs. We provide sample units for buyers to test cable fit, pinout, and mating feel.

Frequently Asked Questions

Q: What does “two-piece” mean? The M8 3-6ピン防水オス型コネクタ（2ピース） consists of the main plug body and a separate rear coupling gland that slides over the cable. You thread the rear piece onto the cable first, terminate the wires in the plug body, then tighten the rear gland. This is the standard field-assembly format for M8 connectors.

Q: Is this the panel receptacle or the cable plug? The M8 3-6ピン防水オス型コネクタ（2ピース） is the male cable-side plug designed to be field-assembled onto a cable. The matching M8 female panel receptacle or cable connector is sold separately. Please specify whether you need the cable plug, panel receptacle, or both when ordering.

Q: What cable diameter does the gland accept? The cable gland on the M8 3-6ピン防水オス型コネクタ（2ピース） accepts cable outer diameters within a specified range. Please confirm the cable outer diameter against the product drawing before ordering, because using a cable outside the gland range will prevent proper sealing.

Q: Is it suitable for outdoor or wet environments? When correctly assembled and mated, the M8 3-6ピン防水オス型コネクタ（2ピース） assembly reaches IP67, suitable for dust-exposed and temporary water-immersion industrial environments. For continuous submersion or outdoor exposed UV environments, we recommend confirming the specific application with our sales team.
