ROTOCON BRUSHLESS SLIP RING ALTERNATIVES PROVIDE MAINTENANCE-FREE PERFORMANCE

Meridian Laboratory’s ROTOCON brushless slip ring technology is engineered for longevity, requiring no maintenance throughout its operational lifespan. They are designed to outperform conventional brushed slip rings, oftentimes exceeding their total revolutions by many orders of magnitude, without changes in performance or degradation over time.

  • Maximize uptime and eliminate the need for slip ring brush replacement, dust clean out, and other necessary maintenance
  • Surpass brushed slip ring longevity without maintenance, adjustments, or replacement
  • Brushless slip ring technology provides stable and consistent performance without degradation over time

IP-Rated Electrical Slip Rings for Harsh Environments

Meridian Laboratory’s ROTOCON brushless slip rings and rotating electrical connectors are environmentally sealed, effectively preventing the ingress of dust, liquids, and external contaminants. They are designed to operate without producing dust, making them the ideal choice for cleanrooms and other sensitive environments. Their robust design ensures that they remain unaffected by vibration, humidity, and other environmental variables, guaranteeing reliable performance under diverse conditions.

  • Environmentally sealed slip ring design prevents ingress from dust, liquids, and other contaminants
  • No generation of dust or particulates during operation
  • Unaffected by temperature, vibration, or humidity for consistent performance

Slip Ring Assemblies for Reliable Power & Signal Transmission

ROTOCON brushless slip rings and rotating electrical connectors are designed to transmit both power and signal within a single slip ring assembly, without the risk of cross-talk or electrical interference between contacts. Regardless of rotational speed or total number of revolutions, they perform with low and stable electrical resistance without arcing or signal loss, which are common weak points of brushed slip rings.

  • Reliable transmission of power and signals without cross-talk or interference between contacts
  • Strong electrical insulation between contacts without shorts
  • Low and stable electrical resistance regardless of rotational speed or total number of revolutions

CONSISTENT CURRENT DELIVERY

Meridian Laboratory’s brushless rotating electrical slip rings and rotary grounds are engineered to transfer stable and consistent electrical current, ensuring there is no fluctuation in resistance and power output over time or during rotation.

  • Low and stable contact resistance guarantees power delivery without fluctuations in electrical current
  • Electrical resistance remains stable and unaffected by rotational speed, indexing use, or total number of revolutions
  • Non-arcing design provides a safe and sealed electrical contact

ROTOCON BRUSHLESS SLIP RINGS DELIVER UNBEATABLE SIGNAL QUALITY

Meridian Laboratory’s ROTOCON brushless rotating electrical slip rings excel in delivering low-noise and flawless electrical connections in rotating applications. Regardless of rotational speed or usage over time, there is no degradation in signal, with transmission comparable to a stationary piece of wire. This makes ROTOCON brushless slip rings the ideal choice for strain gauges, thermocouples, encoder signals, and other sensitive signal applications.

  • Ideal for sensitive, low-voltage electrical signals such as strain gauges, thermocouples, encoders, and more
  • Near zero electrical noise while stationary or during rotation
  • Electrical signal remains unaffected by rotational speeds, vibration, humidity, and other environmental factors

Lossless Data Transmission with ROTOCON Brushless Slip Rings

ROTOCON brushless slip rings offer real-time, lossless Ethernet and data transmission capabilities, ensuring uninterrupted and uncompromised connectivity. They are engineered to support reliable transmission of a broad spectrum of communication protocols. ROTOCON brushless electrical slip rings offer data transmission speed and dependability equal to that of stationary communication cables.

  • Reliable Gigabit Ethernet transmission guaranteed without bit errors or signal loss
  • Robust transmission of many major communication protocols including Ethernet (10/100/1000Mbps), Etherlink, Profinet, Profibus, ControlNet, DeviceNet, CAN-Bus, Serial (RS485, RS432, RS422) USB (1.0/2.0), Modbus, EtherCAT, CC-Link, and more
