The BCH S-71 is a Type S AC Solenoid Operated Brake designed for reliable braking and holding applications in electrically driven industrial machinery. It features an approximately 180 mm (7 inch) brake wheel diameter and a maximum braking torque of 68 Nm (50 lb-ft). BCH specifies the S-71 for continuous-duty operation, making it suitable for applications requiring dependable braking performance over its specified duty conditions.
The BCH S-71 belongs to the AC Solenoids & Brakes – AC Solenoid Brake – Type S range. Type S brakes use an electrically released and spring-applied operating principle, providing a fail-safe braking arrangement. When the solenoid is energized, the brake is released; when the electrical release supply is removed, the spring-applied brake engages.
The 180 mm / 7-inch wheel size and 68 Nm maximum torque rating make the S-71 suitable for appropriately sized machinery and drive applications. BCH's technical catalogue also identifies the AC50D7 as the standard wheel/drum associated with the S-71/S-72 brake family.
The brake can be considered for applications such as conveyors, hoisting equipment, elevators, escalators, machine tools, printing presses, small cranes, overhead doors and other electrically driven machinery. BCH notes that applications involving frequent stopping or heavy inertial loads should be evaluated using factors such as load inertia, shaft speed and stopping frequency.
The BCH S-71 AC Solenoid Brake can be considered for:
The BCH S-71 provides a dependable braking solution for machinery requiring up to 68 Nm of maximum braking torque with continuous-duty capability. Its 180 mm brake wheel makes it suitable for appropriately sized mechanical drive systems.
The spring-applied and electrically released design provides fail-safe braking operation. The brake is released when its solenoid is energized and applied when the electrical release supply is removed, making this principle useful for equipment where dependable stopping and holding are important.
The 68 Nm torque rating provides a defined braking capability for compatible machinery. Actual brake selection should consider the complete application, including shaft speed, load inertia, stopping frequency, required deceleration time and transmitted torque.
The continuous-duty specification makes the S-71 suitable for applications where the brake is required to operate within the specified continuous-duty conditions. For frequent stopping or high-inertia loads, BCH recommends engineering evaluation using the application details.
The 180 mm / 7-inch wheel size places the S-71 in the BCH 7-inch brake family. The corresponding AC50D7 wheel/drum is identified for the S-71/S-72 family.
BCH provides standard coil-voltage selections for Type S brakes, including 110 V, 220 V, 380 V, 415 V and 440 V AC depending on the specified configuration. The appropriate voltage should be confirmed before ordering.
The Class F insulation and industrial Type S construction support use in suitable electrically operated machinery. The brake is designed for long life, easy installation and minimum maintenance according to BCH's product information.
