Servotecnica SVTS A 04 Gold-Contact Capsule Slip Ring (25.0 mm OD)

Technical Overview: SVTS A 04

The Servotecnica SVTS A 04 (SVTS-A-04) is a precision miniature capsule slip ring engineered by Servotecnica S.p.A. for continuous 360° transmission of electrical power, low-noise instrumentation signals, and high-speed data within compact rotary assemblies. Built with a 25.0 mm outer diameter and gold-to-gold precious metal fiber brush contacts (< 10 mΩ dynamic contact resistance), the SVTS A 04 supports Up to 56 circuits (2 A signals / up to 10 A power, 240 VAC/VDC) while minimizing friction torque and electrical jitter.

Rated for continuous operation up to Up to 500 rpm across -20°C to +80°C (Standard ST) or -40°C to +80°C (Extended ET) with IP51 Standard (-S-) / IP65 Optional (-U-) environmental protection, the SVTS A 04 delivers maintenance-free service up to 10 million revolutions. Traditional carbon-block slip rings generate conductive wear debris, elevated contact resistance jitter, and high starting torque that corrupt sensitive fieldbus frames such as Gigabit Ethernet, EtherCAT, PROFINET, and BiSS-C. Servotecnica's precision rotary contact architecture maintains low dynamic contact resistance and crosstalk isolation across continuous 360° rotation.

Designed for straightforward mechanical integration (25.0 mm outer envelope, dedicated shaft/capsule mounting architecture, IP51 Standard (-S-) / IP65 Optional (-U-) environmental protection), the SVTS A 04 supports custom flying-lead lengths, military or industrial connectors, and hybrid pneumatic, hydraulic, RF, or Fiber Optic Rotary Joint (FORJ) passages. TORQUETY LTD (UK Company No. 17124704, London WC2H 9JQ & Oxford +44 1865 679185) provides official UK technical specification support, custom harness engineering, and GBP B2B supply across England, Scotland, Wales, and Northern Ireland.
