There are many types of conductive slip rings, some are distinguished by application, and some are distinguished by shape. For example, there is a hollow shaft in the middle of the through-hole conductive slip ring, so the through-hole slip ring is also called a hollow shaft slip ring. The cap-type conductive slip ring is shaped like a hat, so it is defined as a cap-type conductive slip ring.

Next, we mainly introduce and analyze the distinction between the cap conductive slip ring and the via conductive slip ring:

In terms of rated current, the maximum current per ring of the cap-type conductive slip ring is generally about 2 amps, not too large, too large to easily break through the insulation resistance, and the electromagnetic interference between the ring and the ring is also easy to occur, affecting the signal. The quality of the transmission is prone to signal distortion or scrambling. In a practical application, the cap type slip ring is mainly on a precision small device such as a high-speed ball and a high-definition device. The maximum current and rated current required by such a device are not too large, and the cap type slip ring is mass-produced and standardized. Production, so the cost is low, the price is relatively low. Cap-type conductive slip rings are also very limited in the fields of waterproof and dustproof. Generally speaking, if the RH is relatively high, the cap-type conductive slip ring cannot be used. Moreover, explosion-proof, dust-proof, etc. are required. In the case of special fields, it is also impossible to use a cap-type conductive slip ring.

   A small number of via conductive slip rings are standard products, most of which are custom series. Many special needs of customers can be achieved with through-hole conductive slip rings. Therefore, the cost and price of the through-hole conductive slip ring are much higher than the cap type. Since the outer casing of the through-hole conductive slip ring is made of aluminum alloy, it is not easy to age, crack, and deform, and is very advantageous in many very harsh environments.
