    Miniature slip ring standard models are available from stock. Specifications such as circuit wires quantities, current, and signal are customizable. Slip rings are made of ultra-thick gold-plated, high-performance bearings and rare metal alloy brush wires. The wires at rotor and stator use 24-color colored wire for easier wiring and operation. The conductive rings use 90-degree angle V-groove that expand the contact surface for smoother rotation and reduce torque and dynamic resistance.

    Application: Consumer electronics industries such as security and stage lights, as well as non-civilian fields such as defense, military, and research institutes.

    Tips: Selection for a slip ring

    In general, the slip ring selection needs to consider the following specifications.

    1. The type of transmission signal (current, signal, optical signal, or a mixture of several signals), such as 2-wire 10a, 6- passage signal, etc.
    2. Number of slip ring wires (also called passages/channel)
    3. Dimensions (outer diameter)
    4. Operation speed, rotating speed (that is, how many revolutions per minute, unit is rpm)
    5. Operation temperature
    6. Operation environment
    7. Quality level, whether there is waterproof and dustproof requirements.

    In addition to the basic specifications, as a shafted slip ring, arrangement of the slip ring, ease of installation and disassembly, allowable installation space, size and marketability are also considered.
    When selecting the slip ring, in addition to considering fatigue life of the slip ring, grease life, wear, noise, etc., which occur due to grease aging, also need to be fully considered. In addition, depending on the application, it is necessary to select a slip ring that can move in the axial direction or move on the mounting surface. For relatively short shafts, in the case where the fixed end is not different from the free end, use a one-way fixed, axially moving slip ring. However, there is no order or rule for selecting slip rings. The first thing to consider is the items most relevant to the conditions and performance requirements to the slip ring.
