BTA20.3-NC-DC-BA-BS

The BTA20.3-NC-DC-BA-BS from Bosch Rexroth Indramat is a robust operator interface device in the BTA20 Machine Control Boards series, engineered for demanding industrial environments. This Type: Push Button Switch features a Contact Configuration: Normally Closed (NC) momentary actuation, ensuring precise signal control. Its Bezel Material: Stainless Steel (BS) and Panel Cutout Diameter: 20.3 mm provide durable panel integration, while the Ingress Protection: IP65 rating guarantees reliable operation in harsh conditions. Designed for DC operation, the switch supports a Rated Current: 20A capacity, enabling high-capacity interface tasks.

The control board utilizes a Actuator Type: Button Actuator (BA) combined with a Mounting Type: Panel Mount design for straightforward installation. Compliance with Standards Compliance: IEC/EN 60947-5-1 assures adherence to global industrial safety requirements. It incorporates Terminal Type: Screw Terminal connections for secure wiring and features a resilient Mechanical Life: 1,000,000 cycles for extended service intervals. A designated Design: 3 architecture facilitates consistent performance, while the integrated Communication Bus: INTERBUS-S / BT-BUS enables seamless data exchange within automated networks.

Operationally, the BTA20.3-NC-DC-BA-BS excels in stability and repeatability, benefiting from its Ingress Protection: IP65 enclosure and stainless steel bezel that resist corrosion and wear. The Switch Function: Momentary actuation allows for instantaneous control signals without latching, essential in emergency stop and reset sequences. High-current capability to 20A DC ensures compatibility with heavy-duty relays and contactors, while the screw terminal interface minimizes contact resistance and simplifies maintenance. With a one-million-cycle mechanical life rating, this push button switch supports rigorous daily use in machine control applications.

Integration is straightforward thanks to the device’s Mounting Type: Panel Mount form factor and standardized Panel Cutout Diameter: 20.3 mm. The compatibility with INTERBUS-S / BT-BUS communication protocols provides designers with flexibility to incorporate the switch into modular control architectures. Its DC operating voltage range and high ingress protection make it well suited for factory automation, packaging machinery, and process control panels. As part of Bosch Rexroth Indramat’s BTA20 series, the BTA20.3-NC-DC-BA-BS delivers a reliable, high-performance interface solution for advanced industrial automation environments.
