M12 connector-welding wire short shielded circular metal connector, designed for industrial scenarios, with straight head shape, screw locking structure and metal shell, brass nickel-plated material, support 3-12 pin core configuration, pin core tail welding cable, with short shield shell and IP68 protection level, both durable and sealed, suitable for stable signal transmission in harsh environments.
1. Product Features
This connector is built to industrial standards and has significant core advantages:
Structural design: The straight head is simple and compact, and the screw locking ensures a stable connection, effectively resisting vibration and impact; the metal shell is matched with brass nickel plating process, which is anti-oxidation, anti-corrosion, and prolongs the service life.
Protective performance: The short shielding shell design takes into account electromagnetic shielding and space saving, IP68 dust and water resistance, can be immersed in 1 meter deep water for 30 minutes, and adapts to harsh environments such as dust, moisture, and water.
Flexible adaptation: Supports 3-12 pin core free configuration, and the pin core tail adopts welding cable technology to simplify the wiring process, improve signal transmission stability, and meet the connection requirements of different devices.
2. Product size and number of pin cores
Core size: The outer diameter of the main body is about 14.0mm, the total length is 23.0mm, adapted to M12×1.0 standard thread, compatible with mainstream industrial equipment interfaces; the short shielding shell length is only 9.8mm (female)/11.0mm (male), compact and light.
Number of pins range: Provides multiple specifications from 3 to 12 pins, adapting to multiple scenarios from simple signal transmission to complex data interaction. The welding wire design ensures reliable connection of each pin and reduces the risk of poor contact.
With excellent protection, durability and flexible adaptability, this connector has become an ideal choice for industrial automation, equipment control, outdoor instruments and other fields.
