Basler Electric ACA2040-25GM 4Mp 25Fps Area Scan Camera

The Basler Electric ACA2040-25GM is a high-performance industrial area scan camera designed for machine vision, quality control, and automation applications. It features a 4‑megapixel CMOS sensor with global shutter technology, delivering crisp images at a frame rate of 25 frames per second. The camera is equipped with a standard C‑mount lens interface, providing flexibility in lens selection for various field‑of‑view requirements. Its GigE Vision interface ensures fast and reliable data transmission over long cable distances, making it ideal for factory floor environments.

Sensor and Image Quality

The ACA2040-25GM utilizes a Sony IMX226 or equivalent high‑sensitivity sensor with a resolution of 2048 x 2048 pixels (4 MP). The global shutter eliminates motion blur, enabling accurate capture of fast‑moving objects. With a pixel size of 3.45 µm, the camera delivers excellent image sharpness and low noise, even in challenging lighting conditions. Dynamic range and color fidelity are optimized for industrial inspection tasks such as surface defect detection, measurement, and barcode reading.

Interface and Connectivity

The camera supports GigE Vision standard, with Power over Ethernet (PoE) capability for simplified cabling. Data transfer rates up to 1 Gbps ensure low latency and high throughput. The camera includes a screw‑locked RJ45 connector for secure connection, as well as a general‑purpose input/output (GPIO) port for external trigger and strobe control. It is fully compatible with popular machine vision libraries such as Halcon, OpenCV, and LabVIEW.

Features and Controls

Users can adjust exposure time, gain, white balance, and image ROI (region of interest) via software. The camera supports hardware triggering with low jitter, precise timestamping, and multi‑camera synchronization. An on‑board image buffer accommodates burst captures. The ACA2040-25GM also features sequencer mode for dynamic parameter changes during operation.
