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.

10mm or less

the screw

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.

4 D4222901B

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]

“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.

Overview

This BU406M is an integrated-(one-body)-type monochrome camera employing

high speed CMOS

image sensor

. 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.

Features

2.1 High frame rate

Supported frame rate is up to 90fps (BU406M/4M pixels).

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* conformity

This product is based on USB3 Vision Ver.1.0.

2.5 GenICam* Ver.2.3 conformity

This product is based on GenICam Generic Interface for Cameras Ver.2.3.

2.6 IIDC2* Digital Camera Control Specification Ver.1.0.0 conformity

This product is based on IIDC2 Digital Camera Control Specification Ver.1.0.0.

2.7 e-CON* Connector adoption

The e-CON connector adoption enables to assemble the cable easily without using special tools.

2.8 Decimation

Camera reads all effective areas at high speed by skipping lines.

6 D4222901B

2.9 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.

2.10 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.

2.11 Compact and lightweight

This camera is compact and lightweight; it is easy to integrate into industrial equipment.

2.12 EU RoHS & Chinese ROHS compliant

Functions

5.1 Gain

Manual gain control is available from zero times to 8 times.

Notes on gain setting:

Setting the gain value too high increases noises. When you adjust the brightness of the image, I ask

you to have final image quality checked with your environment.

5.2 Black Level

Black level is adjustable from -25% to +25% as white saturation level is 100%.

5.3 Gamma

Gamma correction curve is adjustable from 0.45 to 1.

5.4 Exposure Time

Manual exposure time control is available. Exposure time is adjustable by the internal sync signal.

8 D4222901B

5.5 Random Trigger Shutter

An image is captured at the desired timing using trigger signal input. External trigger signal from

trigger input connector and software trigger from control command via the USB 3.0 interface are

available (Only in Edge mode). Trigger polarity is selectable (High active / Low active).

Note that Random Trigger Shutter will cause a delay between trigger signal and start of exposure.

See 7. Timing Chart for detail.

- Edge mode (TriggerSequence0)

The exposure time is determined by Exposure Time setting.

- Level mode (TriggerSequence1)

The exposure time is determined by the pulse width of the trigger signal.

- Bulk mode (TriggerSequence6)

Camera exposes and transfers multiple frames by a single trigger.

Note on Random Trigger Shutter:

- When the trigger signal is noisy, there is a possibility of causing the malfunction. In this case, please

input a noise-free signal.
