The metal pin slip ring with compact design has an outer diameter of 32 mm and is designed for applications where internal space is limited and mercury-free is required. This includes gimbal systems, rotary indexing tables, and other precision motion applications. It also has highly conductive metal pins that support high current (2/30A) and low current (2/4A) transmission. This can make its power and signal transmission more stable and reduce electrical noise to the lowest.

Application Scenario

Bottle Labeling Machines

When the labeling machine is working, the bottle rotates 360 degrees around its own central axis at a constant speed to smoothly attach the label to the bottle body. The slip ring installation machine performs real-time signal interaction at its rotating axis, such as transmitting the bottle position and rotation angle.

Medical Imaging Equipment

When the CT machine scans the human body, its frame rotates around the patient to obtain detailed imaging data inside the human body from different angles. It transmits various control signals (such as signals for controlling scanning speed, angle, etc.) and image data signals.

Radar Antennas

The metal pin slip ring with compact design transmits electrical signals from the power supply to the antenna part. Therefore, the antenna can continuously receive and send signals while rotating, and perform positioning, communication, reconnaissance, surveillance, and other functions.

FAQ

Q: How to judge the quality of these slip rings?

A: This can be judged from the following aspects.
(1) Material: High-quality slip rings usually use conductive materials such as gold, silver, copper and POM insulating materials to produce contact parts.
(2) Electrical performance: Determine whether its indicators meet the standard requirements, including contact resistance and insulation resistance.
(3) Manufacturing process: Check the smooth level of the slip ring, and whether the component connection is stable.

Q: How is the price of these slip rings determined?

A: In addition to the necessary material and production equipment costs, transportation costs, installation and commissioning costs, and after-sales service costs are also important factors. Among them, transportation costs depend on the purchase quantity, transportation distance and transportation method. The installation and commissioning costs include labor costs and the required tool and equipment costs.

Q: Are there any benefits to using enclosed capsule slip rings?

A: Since these slip rings allow the transmission of power and signals between stationary and rotating structures without any physical connection, slip rings are less prone to wear than other types of connectors. Without slip rings, cables and wires would twist and tangle, damaging electrical connections and limiting the range of motion of rotating components.
