BTA20.4-NA-CP-VB-BS

The BTA20.4-NA-CP-VB-BS from Bosch Rexroth Indramat is a precision linear actuator in the BTA20 Machine Control Boards series designed for demanding industrial applications. This actuator delivers a stroke length of 20 mm and a rated load capacity of 4000 N, providing robust force in a compact form factor. Operating on a nominal input voltage of 24 V DC with an input current of less than 10 mA, it combines energy efficiency with high performance. Housed in a corrosion-resistant stainless steel enclosure and certified to IP65, the BTA20.4-NA-CP-VB-BS withstands harsh environments while maintaining precise operation. Its type designation as an actuator and overall product design classification of 4 highlight its specialized role in automation systems.

Technical excellence is at the core of this actuator’s capabilities. It supports a duty cycle of 25%, ensuring reliable intermittent operation under heavy loads, with a max current consumption of approximately 1.0 A. The integrated control protocol CP enables seamless communication over the INTERBUS-S / BT-BUS fieldbus, while the onboard connector type VB simplifies wiring and reduces installation time. Position feedback is provided via a built-in potentiometer, guaranteeing accurate linear displacement monitoring. The movement mechanism is optimized for linear actuation, delivering repeatable strokes with minimal backlash, and conforming to the stringent demands of automated machinery.

Operational features emphasize durability and ease of integration. The actuator’s mounting via clevis/pin ensures secure attachment in confined spaces and supports dynamic load cycling. Rated for an operating temperature range of –20 °C to +70 °C, it maintains performance across extreme climates. The configuration marked NA-CP-VB enables dedicated emergency stop and override functions, enhancing safety and process control. With its robust material composition and IP65 ingress protection, the BTA20.4-NA-CP-VB-BS resists dust, water jets, and corrosive agents, minimizing maintenance downtime. Its compact dimensions and lightweight profile streamline system layouts in high-density control cabinets.

Integration into automated systems is facilitated by the actuator’s compliance with industry standards and straightforward connectivity. Engineers can deploy the BTA20.4-NA-CP-VB-BS alongside existing Bosch Rexroth Indramat controllers or third-party INTERBUS networks, leveraging its fieldbus compatibility and custom protocol support. Typical applications include machine tool positioning, packaging line indexing, and assembly automation where precise linear motion and force control are paramount. Its uninterrupted feedback loop and rugged construction make it an ideal solution for retrofits or new installations targeting enhanced process reliability and throughput efficiency.
