Designed for industrial automation, these through hole slip rings for wrapper machines feature a 25mm ID/86mm OD compact design with 10A current capacity. The slip rings support 12-48 circuits with 3m protected cabling (IP65 rated). So they can provide reliable power/signal transmission in wrapper machines, cable reels, and CNC equipment.

Features

Multi-channel

The through hole slip rings for wrapper machines transmit control signals, sensor data, video signals, etc. at the same time. Because it supports 24, 30 or 48 channels of circuit design, different types of signals are integrated in one system for transmission.

High speed

When the equipment runs at a higher speed, the speed of this slip ring reaches 1000 rpm or even higher. Ordinary slip rings fail because they cannot withstand the centrifugal force, friction and heat generated by high-speed rotation.

Easy to connect

It is equipped with a special tube for protection, assembly and waterproofing, to guide the connection with devices. This enables safe wiring in humid environments while preventing signal transmission from being affected by moisture erosion.

Highly sealed

The slip ring uses silicone rings and insulating materials to seal, reaching IP65 protection level. It can withstand stains in the use environment, including exposure to dust, moisture, mud and variable temperatures.

FAQ

Q: How do the Slip Rings for Wrapper Machines work?

A: Slip rings use sliding electrical contacts to transfer electrical signals and power to a rotating interface. These contacts are typically a rotating ring and a stationary brush or wiper that slides along the surface of the ring during rotation. The materials and design methods of these contacts have been optimized to minimize wear and maximize electrical performance.

Q: What materials do you use to make these electrical contacts?

A: There is a wide variety of materials used in slip ring design, each with its beneficial properties. The contact surfaces are almost always alloys of precious metals (usually gold or silver) to minimize surface contaminants and maintain low contact resistance.

Q: What shape are these contacts?

A: Rings come in two basic shapes: cylindrical (drum) or disc (pancake), and the best configuration is the one that works best for your system, i.e., whatever your physical limitations are in terms of length or diameter. Brush selection criteria include size, power requirements, ring configuration, and life requirements.

Q: Is there a speed limit for through hole slip ring?

A: Yes, the speed of the slip ring is limited. We do have some special designs that can operate up to several thousand rpm, but this may vary with several parameters such as size, material, and environment, due to the following factors.
