Brushless Hollow-Shaft Slip Rings

Traditional brushed slip rings rely on metal-on-metal contact to transfer power between stationary and rotating components. ROTOCON hollow-shaft slip rings do not have any internal wear parts, and therefore do not require any maintenance, adjustment, or replacement of parts during the lifetime of their use.

• No metal-on-metal contact
• 100% maintenance-free
• Outlast traditional brushed slip rings
• Routinely surpass 500m+ total revolutions

ROTOCON hollow-shaft slip rings transmit high-speed Ethernet-based communication up to 100 Mbps reliably and without bit errors, packet loss, or crosstalk. They are also capable of many other communication protocols, including Etherlink, Profinet, EtherNet/IP, Profibus, Modbus TCP/IP, Powerlink, CC-Link IE, SERCOS III, SynqNet, MECHATROLINK-III, ControlNet, RS485, RS432, RS422, EtherCAT, and more.

• Guaranteed ethernet transmission without bit errors or crosstalk
• High speed capable up to 100 Mbps
• Compatible with many other digital communication protocols

ROTOCON hollow-shaft rotating electrical connectors are unique in their ability to provide excellent analog signal transmission, without fluctuation or noise – whether stationary or while rotating. They are the ideal choice for sensitive electrical signals such as encoders, thermocouples, strain gauges, and more.

• Perfect signal integrity – regardless of speed
• Near-zero electrical noise
• Excellent for analog signal transmission

ROTOCON hollow-shaft slip rings are environmentally sealed to provide a superior rotating electrical connection. They are sealed from the outside environment and remain unaffected by dust and liquids, as well as humidity and other environmental factors that conventional brushed slip rings are challenged by. They are internally arc-free making them the ideal choice for wet, dust-filled, cleanroom, and other challenging operating environments.

• Environmentally sealed design
• Unaffected by liquids, dust, and other factors
• Robust design for harsh environments

Traditional slip rings often face challenges when transmitting both power and signal within a single assembly, leading to noise and interference issues. ROTOCON hollow-shaft slip rings and rotating electrical connectors are uniquely designed to deliver lossless signal transmission with zero electrical interference, ensuring reliable performance in demanding applications.

• Supports AC/DC power and signal transmission within a single assembly
• Ensures reliable Ethernet, encoder, strain gauge, and other sensitive signals
