M12 connector-assembled straight plastic connector is an ideal connection solution in the field of industrial automation. It adopts a screw locking structure and a lightweight plastic shell. The internal brass nickel-plated contact has both conductivity and oxidation resistance. It is equipped with a cable locking design to effectively resist vibration and external force pulling. The product provides a variety of pin core options (3-12 pin cores) to meet the needs of different scenarios. It is easy to install and has an excellent protection level, providing a stable and reliable solution for equipment connection.
1. Product Features
The connector is designed to be assembled quickly, and its core advantages include: ① Screw locking mechanism: through precise thread fastening, it ensures stable signal transmission, anti-vibration and anti-shock; ② Lightweight plastic shell: using high-strength engineering plastics, chemical corrosion resistance, good insulation, and reducing the weight of the equipment; ③ Brass nickel-plated contacts: the internal conductive parts are nickel-plated, with excellent conductivity, strong anti-oxidation ability, and extended service life; ④ Cable locking structure: suitable for a variety of cable specifications, tightly fit after locking, effectively preventing poor contact caused by pulling.
2. Product size and number of pins
Size specification: Two mainstream models are provided to adapt to different installation spaces-
Male head: body diameter 56mm (refer to the size diagram), adapted to M12×1 threaded interface;
Female head: body diameter 52mm (refer to the size diagram), also using M12×1 standard interface, taking into account compactness and versatility.
Number of pins selection: Covering the full-scenario needs of 3-12 pins, subdivided into A/B/D types and other specifications:
A-type series: 3-pin, 4-pin, 5-pin, 8-pin, 12-pin (both male and female pinholes support multi-pin layout);
B-type/D-type: 5-pin, 4-pin (adapted to lightweight connection of specific equipment).
Both male and female pinholes adopt standardized layout (such as A-type 5-pin male pins are symmetrically distributed from 1 to 5), compatible with mainstream equipment in the market, and strong installation compatibility. The product combines functionality and flexibility, and is the preferred solution for industrial control, sensor connection, and equipment integration.
