iRAYPLE A3131 Series GigE Area Scan Camera (1.3MP PYTHON1300)

A3131MG000E

The iRAYPLE (Huaray) A3131 is a 3000-series GigE Vision area scan camera using the 1/2" ON Semiconductor PYTHON 1300 global-shutter CMOS sensor at 1280x1024 (1.3 MP) with 4.8 x 4.8 um pixels and 60 fps full-resolution output. It offers 10-bit depth, >38 dB SNR, 60 dB WDR, 1x-32x gain and 1 us to 1 s exposure, with 256 MB onboard image buffer. The interface is Gigabit Ethernet (1 Gbps, up to 100 m), conforming to GigE Vision V2.0 and GenICam, powered by PoE or 9-24 VDC via a 6-pin Hirose connector, with a C-mount and a compact 29x29x42 mm housing. Variants include monochrome (A3131MG000E / A3131MG100E) and color (A3131CG000E).

Technical overview

The iRAYPLE A3131MG000E is a 1.3-megapixel GigE Vision area scan camera built on the ON Semiconductor PYTHON 1300, a 1/2-inch global-shutter CMOS sensor running 1280 x 1024 at a steady 60 fps over its full frame. The defining choice here is the global shutter paired with 4.8 x 4.8 um pixels: every pixel is exposed simultaneously, so parts moving down a conveyor or held on a robot end-effector are captured without the skew and smear a rolling shutter would introduce. That makes this a camera for motion, not for static bench scenes where a cheaper rolling-shutter part would do. The 1.3 MP resolution is modest by today's standards, so it earns its keep on tasks where 1280 x 1024 comfortably resolves the feature of interest at the required field of view, rather than on fine-pitch or wide-area inspection that demands 5 MP and up.

The interface is plain Gigabit Ethernet, conforming to GigE Vision V2.0 and GenICam, which is the practical heart of this camera's appeal. A single 1 Gbps cable carries both data and power when you run PoE, and the interface supports cable runs up to 100 m, so the camera can sit far from the controller without repeaters or media converters. If PoE is unavailable, it accepts 9-24 VDC through a 6-pin Hirose connector. GenICam conformance means it drops into mainstream vision libraries and SDKs without bespoke drivers, and the 256 MB onboard image buffer absorbs short bursts and network jitter so frames are not dropped during transfer. Power draw is a low 3.4 W, and the housing is a compact 29 x 29 x 42 mm at 88 g, which matters when the camera rides on a moving axis or packs into a tight fixture.

On the imaging side, the sensor delivers 10-bit depth, greater than 38 dB SNR and 60 dB wide dynamic range, with electronic gain from 1x to 32x and exposure adjustable from 1 us to 1 s. That exposure floor of 1 microsecond is what lets a global shutter freeze fast motion when paired with a bright strobe, while the 60 dB WDR helps hold detail across scenes with both bright and shadowed regions. This is the monochrome variant (A3131MG), which gives you the full per-pixel light sensitivity and the cleanest contrast for measurement, defect detection and code reading; a color sibling (A3131CG000E) exists if your task genuinely needs color. The C-mount accepts the broad ecosystem of standard machine-vision lenses, and the 1/2-inch format keeps lens cost and size reasonable. A wide -30 to +50 degC operating range suits the camera to cold-store, outdoor-adjacent or warm enclosure environments.

Best for

  • Inline inspection of parts moving on a conveyor or indexer, where the global shutter freezes motion and 60 fps keeps up with line speed
  • Robot-guidance and pick-and-place vision on a moving end-effector, where the compact 88 g body and global shutter give distortion-free frames in motion
  • Reading and verifying 2D codes and printed characters (DataMatrix, OCR/OCV) on packaging and labels at moderate resolution
  • Dimensional gauging and presence/position checks where 1280 x 1024 over a well-chosen field of view resolves the feature of interest
  • Distributed multi-station cells where a single PoE Ethernet cable simplifies powering and cabling cameras up to 100 m from the controller

Selection notes

  • Confirm 1.3 MP is enough for your tolerance: at 1280 x 1024 the achievable measurement resolution depends entirely on field of view, so size the FOV so the smallest feature spans enough pixels before committing.
  • Plan for strobe or pulsed lighting if you image fast motion; the 1 us minimum exposure only freezes movement when paired with sufficient light, and external trigger plus a lighting controller is the standard pairing.
  • Budget the GigE link: at 60 fps full-frame this camera streams continuously, so use a dedicated NIC with jumbo frames, and exploit the 256 MB onboard buffer to ride out short network contention.
  • Decide PoE versus 9-24 VDC early; PoE reduces cabling to one line but requires a PoE switch or injector, while the 6-pin Hirose route needs a separate supply.
  • Choose mono versus color deliberately: the A3131MG mono gives maximum sensitivity and contrast for measurement and code reading, while the A3131CG000E color variant is only worth the sensitivity penalty when the task needs color discrimination.
  • Select a C-mount lens matched to the 1/2-inch sensor and the camera's 4.8 um pixels so the optics resolve detail the sensor can capture, and verify the lens covers your working distance and FOV.
