B series push pull connector metal circular IP50 indoor used with 360 degree EMC shielding

Short Description:

The B series product is a circular push-pull self-locking connector with a double-layer metal shell with 360 degree EMC shielding function. It has a waterproof rating of IP50 and is more suitable for indoor use.

B series products are the earliest products developed by our company. They have complete models and sizes. The number of cores ranges from 2 cores to 32 cores, and the shell size ranges from size 00 to size 4. There are many structural styles for customers to have many choose.

B series products have low cost and short delivery time, which can save costs and shorten the delivery time for customers.

Product Details

In addition to excellent electrical performance, the B series connectors can make your device looks high-end and reliable in quality. It has a beautiful appearance and a very smooth push pull feeling. Four kinds of size and five kinds of coding, which can let us have more choice of connectors on the same device without worry about mis-mating. Different colors of over-moulding can also increase the recognition of the product, and the lower cost can make your product have a better competitive advantage in the market. The shell is made of brass as the base material, which is plated with nickel and chrome, which can increase the corrosion resistance and increase abrasion resistance. The contacts also made of copper alloy as the base material, which is plated with nickel and gold, which can increase contact reliability, reduce contact resistance, resist oxidation, corrosion and enhance solderability.

There is a wire clip at the end of the plug, and the cable range can be from 1mm to 10.5mm. The structure design similar to the claw can make the wire clip firmly fix the cable, even if the cable is subjected to external forces such as swinging, pulling, etc. , in this case, it will not affect the reliability of the soldering. The plug and socket automatically lock after being inserted, and even a destructive force of 200N cannot separate them, but if you hold the plug shell by hand and pull it lightly, the plug and socket can be quickly separation, it can saving the operation time.

It can be said that the B series is a very perfect product, except that its protection level is slightly insufficient. We recommend that your products for indoor use can use our B series connectors as much as possible.

B series products are widely used in various fields such as medical treatment, test equipment, automobile crash test, handheld equipment, communication, etc., and are favored by customers.



Our connectors are often used in the interface of equipment to transmit electrical signals. The 360-degree shielding performance can ensure that the signal will not be disturbed by the external signal during the transmission process, nor will it interfere with the external signal.


The physiological signals emitted by the patient's body are very weak. To transmit these signals truly, the impedance of the connectors and cables is required to be very low. The excellent materials and good gold-plating process of our pins and socket can ensure this.


Handheld detection equipment: Good shielding performance, reliable contact performance and shock resistance can make the handheld detection equipment work well while moving, and the reliability of the data will not deteriorate.

Automotive Crash Test: The features of low cost, high density, and multiple positioning, enabling our product can be used in automotive crash test equipment.
