USAGE PRECAUTIONS

 Handle carefully

Do not drop the equipment or allow it to be subject to strong impact or vibration, as such action may cause malfunctions. Further, do not damage the connection cable, since this may cause wire breakage.

 Environmental operating conditions

Do not use the product in locations where the ambient temperature or humidity exceeds the specifications. Otherwise, image quality may be degraded or internal components may be adversely affected. In particular, do not use the product in areas exposed to direct sunlight.

 Combination of C-mount lens

Depending on the lens you use, the performance of the camera may not be brought out fully due to the deterioration in resolution and brightness in the peripheral area, occurrence of a ghost, aberration and others. When you check the combination between the lens and camera, be sure to use the lens you actually use. When installing a lens in the camera, make sure carefully that it is not tilted. In addition, use a mounting screw free from defects and dirt. Otherwise, the camera may be unable to be removed. As for the C-mount lens used combining this product, the projection distance from bottom of the screw should use 10mm or less.

 Mounting to a pedestal

When mounting this product to a pedestal, make sure carefully that the lens doesn't touch with the pedestal.

 Do not expose the camera’s image-pickup-plane to sunlight or other intense light directly.

Its inner CMOS sensor might be damaged.

 Occurrence of moiré

If you shoot thin stripe patterns, moiré patterns (interference fringes) may appear. This is not a malfunction.

 Occurrence of noise on the screen

If an intense magnetic or electromagnetic field is generated near the camera or connection cable, noise may be generated on the screen. If this occurs, move the camera or the cable.

“This symbol is applicable for EU member states only”

 Defective pixels

A CMOS image sensor is composed of photo sensor pixels in a square grid array. Due to the characteristics of CMOS image sensors, over- or under-driving of the pixels results in temporary white or black areas (as if these are noises) appearing on the screen. This phenomenon, which is not a defect is exacerbated under higher temperatures and long exposure time.

 Image shading

The brightness of the upper part of the screen may be different from that of the lower part. Note that this is a characteristic of a CMOS image sensor and is not a fault.

USAGE PRECAUTIONS

 Handling of the protective cap

If the camera is not in use, attach the lens cap to the camera to protect the image pickup surface.

 If the equipment is not to be used for a long duration

Turn off power to the camera for safety.

 Maintenance

Turn off power to the equipment and wipe it with a dry cloth. If it becomes severely contaminated, gently wipe the affected areas with a soft cloth dampened with diluted neutral detergent. Never use alcohol, benzene, thinner, or other chemicals because such chemicals may damage or discolor the paint and indications. If the image pickup surface becomes dusty, contaminated, or scratched, consult your sales representative.

 Disposal

When disposing of the camera, it may be necessary to disassemble it into separate parts, in accordance with the laws and regulations of your country and/or municipality concerning environmental contamination.

[Phenomena specific to CMOS sensor]

D4253375C

1. Overview

This BU CMOS series is an integrated-(one-body)-type camera that adopts a global shutter CMOS sensor. These are BU302MG (3M type1/1.8) BU505MG (5M type2/3). Suffix [CG] or [CF] are attached

to the color models. For video output and camera control, the USB 3.0 interface standard is adopted

for high transfer rate, and it is easy to integrate into industrial equipment.

2. Features

2.1 High frame rate

Supporting high frame rate, BU302MG 120fps, BU505MG 75fps.

2.2 Global shutter

As it employs a global electronic shutter similar to a CCD image sensor, clear images of even

fast-moving object are obtainable with less blur.

2.3 USB* 3.0 interface

Video output and camera control are performed via the USB 3.0 standard interface. Data transfer

is up to 5Gbps (Maximum) that enables to output uncompressed video data at high frame rate.

2.4 USB3 Vision*

This product is based on USB3 Vision Ver.1.0.

D4253375C

2.8 Random Trigger Shutter

The Random Trigger Shutter function provides images in any timing by input of an external trigger

signal. Trigger control from PC is available as well.

2.9 Scalable

Selectable video output area. This mode achieves higher frame rate by reducing vertical output

area. And reduces occupied data rate of USB bus by reducing horizontal output area.

2.10 Binning

B/W models have binning. In this mode, pixel data is combined by vertical and horizontal. Vertical

binning achieves high frame rate.
