M5/M8/M9/M12/M16/M23/GX IP67 metal and plastic circular connecto

Short Description:

M series products are widely used. This product is referred to as “European standard” product. It was originally developed by some large European connector manufacturers such as Pentax and Hummel, etc., but because the product has low cost and high performance, it is easy to batch. Production and other characteristics, it has become one of the circular connectors with a very large number of production worldwide.

This product is mainly classified according to the diameter of the opening. There are M5/M8/M9/M12/M16/23/GX and other sub-series products, which can be applied to various equipments that have requirements for the opening size. For example, M5 means that the hole size of the socket is 5mm.

Relatively speaking, this product is used the most in industrial equipment.

Our products are compatible with some international brands, and even we have developed a variety of novel products, which were not available on the market before.

Product Details

Compared with other circular series products of the same type, M series products have the advantages of low cost, fast delivery and complete model series. Most of the M series products adopt the structure of thread locking, which can make the products lock firmly and have strong anti-vibration and so on. The hole size is from 5mm to 23mm, and the number of cores is from 2 to 24. It can be used to produce plug and cable assemblies of various angles by injection molding. M series products can pass at least 48 hours of salt spray test, -50~155 degrees Celsius operating temperature, at least 500 times of mechanical plug life, with the function of transmitting power and current at the same time and so on. In addition, the M series products are also very flexible in installation, you can choose to install front and rear.

 Bexkom pays attention to product quality, and implements high requirements and high standards in terms of raw material selection, electroplating quality, processing accuracy, and defect management. Although we know that this will cause our product cost to be higher than other peers, but in any case , we put the quality of our products first.

 The plastic shell series of the M series products will cost less than the metal shell series, and can achieve at least IP67 waterproof function, but unfortunately the plastic series does not have the EMC shielding function.

    (1) Can your products be the same or compatible with some of the more famous brands on the market? Are there intellectual property or patent disputes between you?    Some of our products can be fully compatible with LEMO, ODU, Fischer, FCI, Hiros, Binder and other group name brands, but our own design can ensure that we will not infringe their patents, and there is no intellectual product dispute between us.  (2)  Can you provide samples for free? Yes, we can provide a small amount of test samples for free according to the project situation, but the freight needs to be borne by the customer.

     (3) What is your production process?

    1. After the production department receives the assigned production order, the production plan will be arranged. 2. Relevant departments will conduct project review and evaluation as soon as possible to ensure that the production capacity meets customer requirements. 3. Check and confirm the BOM, if there no problem, then material distribution and production equipment debugging. 4. Prepare the corresponding operation documents and confirm by the engineering team. 5. The first sample is produced and confirmed.    6. Mass production. 7. Quality inspection. 8. Packing and storage.

    (4) How long is your normal product lead time?
