Through-hole slip ring DHK028-5

hollow-shaft2-partmedical

Short Description
DHK028-5 2-part enclosureless slip ring. Inner diameter (through hole): 28 mm. Number of circuits: 5. Rated current per circuit: 2 A–50 A (customizable). Designed for OEM integration with rotor and stator supplied as separate units to save installation space and weight. Rotor available in hollow-shaft versions with various inner diameters. Mounting options: screw fixation or adhesive bonding. Custom power-and-signal configurations available.

Product Detail
Developed for limited installation spaces, the open 2-part structure separates the ring channel and brush board so rotor and stator can be mounted independently. The split design reduces installation footprint and weight. Contacts use a V-groove, gold-plated design for oxidation resistance and wear performance.

Typical Applications

• Industrial machinery: drilling platforms, winding machines, end-face machining, hot rolling mills
• Rotary machines: filling machines, bottle blowers, amusement equipment
• Cable drums: port machinery, hoists, road and bridge machinery, towers
• Test equipment: centrifugal test benches, separators, measuring instruments
• Robotics: packaging lines, stackers, process control equipment, presses
• Exhibition/display: revolving booths, turntables, revolving restaurants
• Medical equipment: shadowless surgical lamps, imaging and communication equipment

Product Naming Description

• Product type: DH — electric slip ring
• Installation method: K — through hole
• Through hole bore diameter: 28 mm
• Total circuits: 5
• Rated current: specified per circuit; different ratings may not all be marked
• Identify number: -XXX distinguishes specifications of the same model

Notes
Open, enclosureless design intended for OEM integration where rotor and stator are mounted separately. V-groove, gold-plated contacts offer oxidation resistance and improved wear characteristics. Hollow-shaft variants and multiple mounting options are available. Combined power-and-signal customizations supported.
