1. Product Introduction
3Pin M8 Cable is a 3-pin cable with M8 circular connector, designed for industrial automation environment. M8 connector has compact size (8mm diameter) and high protection level, suitable for signal and power transmission of sensors, actuators, industrial networks and other equipment. Its thread locking mechanism provides a stable connection and excellent vibration resistance.
2. Main application areas
Industrial sensors: connection of photoelectric sensors and proximity switches
Factory automation: distributed connection of PLC and I/O modules
Robotics: sensor/actuator wiring of robot arm joints
Process control: signal transmission of flow meters and pressure transmitters
Onboard electronics: connection of engineering vehicle equipment
Food and medical equipment: application of sanitary stainless steel M8 connector
3. Purchase advice
1. Protection level selection:
Ordinary workshop: IP67
High pressure washing/outdoor: IP68
2. Cable type:
Fixed installation: PVC outer skin
Mobile occasions: PUR outer skin (oil-resistant and bending-resistant)
3. Wiring method:
Straight/elbow connectors are selected according to space limitations
With or without cable glands
4. Certification requirements:
UL/CE certification (North America/EU market)
5. Special needs:
Shielded model (for high-frequency signals)
Highly flexible model (for continuous bending applications in robots)
4. Safety precautions
Current limit: generally not more than 4A (specific model specifications need to be confirmed)
Wiring direction: avoid plugging and unplugging under power
Bending radius: ≥8 times the wire diameter for dynamic applications
Ambient temperature: PUR outer skin is usually -40ºC~+80ºC
Chemical contact: avoid strong acid and alkali corrosion (except for special models)
Installation and fixation: use cable glands to prevent tension damage
5. Frequently Asked Questions (FAQ)
Q1: How to choose between M8 and M12 connectors?
A: M8 is suitable for space-constrained low current (≤4A) applications, and M12 is used for higher current/more pin count requirements.
Q2: Are the pin definitions of 3Pin M8 uniform?
A: Not uniform! Common definitions:
- Sensor: 1(+), 2(-), 3(signal)
- Power supply: 1(L+), 2(L-), 3(PE)
Q3: Can it be used for Ethernet communication?
A: Standard 3Pin cannot, special 4Pin M8 or 8Pin M12 is required.
Q4: Maximum allowable cable length?
A: Depends on the signal type:
- Digital signal: ≤100m
- Analog signal: ≤30m (anti-interference design required)
- Power transmission: ≤15m (at 4A)
6. Summary
3Pin M8 Cable is a high-reliability connection solution in the field of industrial automation. Its compact design and excellent environmental resistance are particularly suitable for sensor networks, mobile devices and harsh industrial environments. Correct selection needs to consider:
1. Electrical parameters (current/signal type)
2. Mechanical requirements (bending/vibration conditions)
3. Environmental factors (humidity/chemical contact)
99.9% oxygen free copper material, copper core, non flammable and safer to use. The outer skin is made of brand new PVC material, which is soft, durable, effectively oxidized, odorless, safe to use, and can be purchased and used with confidence.
Using environmentally friendly new wire, the outer layer is tough and resistant to pulling, bending and not easily broken. The internal and external materials are flame retardant and not easy to burn, so you can use it with confidence!
The power cord is wrapped in PVC material, which is flame-retardant, heat-resistant, flame-retardant, and does not leak electricity, making it more reassuring. Pure copper core has stable transmission, good conductivity, low resistance, low heat generation, stable transmission, and sufficient power supply.
