45-Way 2A Cap-Type Slip Ring
The 45-channel 2A cap-type slip ring integrates up to 45 independent channels within an aluminum alloy housing with an outer diameter of only 25mm. Each channel is capable of transmitting 2A of current or signal. Featuring premium gold-to-gold contact materials and AWG28# Teflon wires, this product supports a working voltage of 240V and rotation speed of 250 RPM. Specifically designed for precision instruments and miniature automation equipment requiring high channel counts in extremely limited installation spaces.

Frequently Asked Questions
Can all 45 channels operate simultaneously at a full load of 2A?
Electrically, all channels support simultaneous operation. However, when operating at full load, the temperature rise due to total power consumption needs careful consideration. We recommend providing specific application conditions so our engineers can assist with thermal simulation assessments to ensure stable and reliable operation in your environment.
How much longer is the lifespan of gold-to-gold contacts compared to other materials?
Under the same operating conditions, gold-to-gold contacts typically have a cycle life an order of magnitude higher than ordinary copper-based or silver-based materials, due to excellent arc oxidation resistance and low friction coefficient. This makes them particularly suitable for high-end applications requiring long life and maintenance-free operation.
What is the installation thickness (height) of the cap-type structure with a 25mm outer diameter?
The axial installation dimension (height) of the cap-type slip ring is also very compact. Please refer to the detailed product drawings for specific dimensions. This design maximizes space savings in both the axial and radial directions of the equipment.
