SHINE M12 Field Wireable Connector Purchase Guide

Field wireable M12 connectors allow users to create custom cables by attaching wire to the connector and terminating it using one of several methods, such as screw, solder, or crimp. These connectors are popular because they offer a quick and flexible solution for small quantity applications or field maintenance. The M12 field wireable connectors is also called M12 cable assembly connector or M12 field attachable connector, can be sorted by following methods:

  • Pin quantity: They are available in a range of pin counts, such as 2-pin, 3-pin, 4-pin, 5-pin, 6-pin, 8-pin, 12-pin, 17-pin
  • Coding type : To meet different application, the common coding systems have A-coded, B-coded, D-coded, X-coded, S-coded, T-coded, L-coded, and M-coded, each of which corresponds to a specific configuration of pins.
  • Shell material: Can be made with different shell materials, for example PA66, Zinc, stainless steel.
  • Termination : The connectors have screw, solder and crimp terminations. 

The professional M12 field wireable connector manufacturers have Binder , Murr , Turck , Phoenix , BELDEN . The connectors from different producers can be compatible with each other as long as they are coded the same way and have the same number of pins. However, it is always a good idea to double-check compatibility before purchasing or using connectors from different brands.

Pin Quantity

M12 cable assembly connectors are available in a range of pins, including 2, 3, 4, 5, 6, 8, 12, and 17 pin configurations. The number of pins corresponds to the number of electrical connections that the connector can make. M12 12 pin, 8 pin, 17 pin field wireable connector are used for data transmission . M12 5 pin, 4 pin, 3 pin field wireable connector are used for sensor or actuator in automation industry .

M12 field wireable connectors are available for solder, screw, and crimp termination, the different termination methods have advantages and disadvantages.

  • Screw termination is the most popular and easy to use, but has poor anti-vibration performance. 
  • Solder termination requires more skill and is at risk in extreme temperature environments, but supports a larger range of pin numbers. 
  • Crimp termination has good anti-vibration and temperature performance, but requires special tools and skills, it can be mass assembled with crimp equipment. It is important to choose the right type of connector based on the specific requirements of the application.

Shell Material

M12 field wireable connectors may have shells made of differerent materials, mainly have PA66, Zinc alloy, stainless steel.

  • PA66, also known as nylon, is a commonly used material for M12 field wireable connectors due to its good mechanical properties, heat resistance, wear resistance, chemical resistance, and self-lubrication. It also has a low friction coefficient, certain flame retardancy, and is easy to process, which makes it a cost-effective choice for many applications. 
  • Zinc alloy is another popular material for M12 field wireable connectors because it has good mechanical properties, corrosion resistance, and shielding properties, and is easy to process. It is often used in automation systems with relatively high requirements. 
  • Stainless steel is a more expensive material for M12 field wireable connectors because it can only be processed by CNC and has a lower production efficiency. However, it has excellent oxidation resistance, corrosion resistance, mechanical properties, oil resistance, and is easy to clean, which makes it a good choice for certain applications.
