1. M6 Connector Specifications

Electrical & Mechanical Parameters

- Pins: 2pin, 3pin, 4pin, 5pin, 6pin available; 3pin,4pin and 6pin are the most common.

- Electrical: Designed mainly for low-voltage signals. Rated voltage: 30V; rated current up to 2A per pin. Gold-plated contacts ensure stable contact and anti-oxidation performance.

- Protection Rating: IP67 when mated, dustproof and waterproof, suitable for humid and dusty workshop environments.

- Mounting: Panel soldering receptacles (front / rear lock), straight and right-angle 90° versions; termination by soldering or crimping.

- Temperature Range: -40℃ ~ +85℃; mating cycle ≥1000 times.

- Coding: Mainly A-Code for anti-misplug, preventing equipment damage caused by incorrect mating.

2. . Core Advantages of M6 Connector

✅ Compact Size: 6mm thread outer diameter, smaller than M8, ideal for tight internal equipment space.

✅ Stable Signal: Gold-plated contacts with vibration resistance, suitable for weak signal transmission of sensors.

✅ Flexible Mounting Options: Overmolded cable plugs + PCB panel receptacles, straight or right-angle options for flexible wiring.

✅ IP67 dust and water resistance, reliable connection under harsh industrial conditions.

✅ Standardized interface, compatible with industry standard parts of the same specification for easy replacement.

3. Main Application Scenarios

- Miniature displacement sensors, photoelectric sensors, proximity sensors (e.g., sensor manufacturers like MIRAN)

- Small automation equipment, precision inspection instruments, miniature medical devices

- Intelligent equipment, small robots, signal harness for vision inspection modules

- Small electric equipment, outdoor miniature sensing acquisition devices

4. Simple Comparison: M6 vs M5 vs M8

- M5: 5mm outer diameter, the smallest size, mostly 3/4pin, for equipment with extremely limited space

- M6: 6mm outer diameter, 2~6pin, balances dimension and pin count, acts as an upgraded version of M5

- M8: 8mm outer diameter, more pins and higher current capacity, the most widely used model for sensors

5. M6 Connector Selection Guidelines
