BLA21 Series (Type A: Outdoor-Compatible, High-Durability Model)

Features

Type A of the BLA21 Series is designed with a rugged housing and enhanced noise resistance for use in more demanding environments.
It offers a wide operating temperature range from -40°C to +70°C (-104 to +158°F) and conforms to IP67 for dust and water protection, making it suitable for outdoor applications. Ball bearings are used in the shaft support to provide high structure durability.
The lineup includes a side-connector model (BLA21-06U-A02) as well as high-voltage models (BLA21-12U-A01 and BLA21-28U-A01).
In addition to DroneCAN v1 (formerly UAVCAN v0), certain models also support PWM communication.
