M12 Connector Straight Circular Plastic Connector

M12 Connector Straight Circular Plastic Connector, designed for industrial scenarios, uses a contact surface concave process to improve contact stability, and is equipped with screw locking to prevent falling off. The lightweight plastic shell is both corrosion-resistant and portable, and the internal brass nickel-plated conductor ensures conductivity and service life. Supports multi-pin configuration (3-12 pins), adapted to M12 standard interface, compact size (diameter 20mm, length 53/57mm), protection level up to PG7, is an efficient solution for equipment connection and signal transmission.

1. Product Features
​​Concave contact surface design: The concave structure of the contact point enhances the plug-in stability, reduces the contact resistance, and improves the reliability of signal transmission;
​​Screw locking mechanism: Standard fastening screws effectively prevent loosening caused by vibration or external force, and ensure long-term safety;
​​Plastic shell advantages: High-strength engineering plastics are used, and the lightweight design reduces the installation burden. At the same time, it has chemical corrosion resistance, high and low temperature resistance, and is suitable for complex industrial environments;
​​High-quality conductive core: The internal conductor uses a brass substrate and is nickel-plated, which has strong antioxidant ability, excellent conductivity, and extends the service life of the connector.

2. Product size and number of pins
​​Dimensional parameters:
The shell diameter is unified to 20mm, suitable for M12 standard thread (pitch 1.0mm);
Length: male head length 53.0mm, female head length 57.0mm;
The protection level reaches PG7, meeting the IP67 dust and water resistance requirements, suitable for humid and dusty scenes.
​​Number of pins configuration​​:
Provide a variety of pin number options, covering 3 pins (Type A), 4 pins (Type A/Type D), 5 pins (Type A/Type B), 8 pins (Type A), 12 pins (Type A), support multiple functional combinations such as signal and power, adapt to different equipment connection requirements, and have strong flexibility.
This connector has a compact design, high compatibility and durability, making it an ideal choice for industrial automation, equipment control, sensor connection and other fields.
