BR018 by Sanyo Denki

The Sanyo Denki BR018 encoder is a precision device in the High Accuracy Absolute Encoders series designed to provide robust voltage dissipation for industrial servo braking systems. This resistor encoder unit manages regenerative energy by diverting excess voltage into internal resistor banks, ensuring safe deceleration cycles without compromising drive electronics. Constructed with a durable brass body and finished in Black RAL coated material, the BR018 maintains mechanical integrity under continuous operation. The unit features a thread size of 1/8" NPT interface for straightforward integration into existing piping or mounting systems.

The BR018’s technical parameters define its industrial performance envelope. It is CE marked to confirm compliance with international safety regulations and supports an operating pressure up to 1200 psi. The encoder’s temperature range of -65°F to 250°F (-54°C to 121°C) allows reliable operation in extreme thermal environments. A humidity tolerance up to 95% ensures functionality in high-moisture conditions commonly found on factory floors. With a length of 0.69 inch and a compact type: resistor encoder unit format, the BR018 minimizes the spatial footprint within control cabinets.

Operational features of the BR018 emphasize continuous reliability and ease of maintenance. A single axial fan draws ambient air across the resistor grids and expels it through a slotted grille outlet, providing forced ventilation that stabilizes internal temperatures during peak duty cycles. The use of ceramic-insulated resistors grants high thermal endurance for short-term overload conditions, while the black coating resists corrosion in demanding settings. Mounting is facilitated by two flanged mounting bases with pre-drilled holes, allowing both vertical and horizontal attachment schemes. Passive and active cooling synergy ensures steady performance without undue noise or vibration.

System integration is streamlined by the BR018’s standardized NPT fitting and terminal strip output connections for control lines and power paths. The unit’s compact form factor and compliance with CE marked directives make it suitable for industrial automation platforms, servo motor braking systems, and power conversion modules. Manufacturers specifying regenerative braking hardware will find the BR018’s combination of high-pressure tolerance and broad thermal range ideal for maintaining system stability under dynamic loads.
