TM-4200GE Hardware

Hardware Introduction

7.2 Features

• Small size and light weight

The printed circuit boards in the TM-4200GE have been arranged to create modular electronics,

giving the camera flexibility. In addition, the use of miniature solid-state components results in a

compact, lightweight camera that is 51mm x 51mm x 74mm in dimensions, and weighs only 155

grams.

• Imager

The TM-4200GE uses a dual-tap progressive scan interline transfer CCD that has the following

features:

- Resolution of 2k x 2k active pixels for excellent image quality.

- 7.4 x 7.4 µm square pixels for precise dimensional measurement.

- High-speed electronic shutter capability for high dynamic resolution of moving objects that

eliminates the need for a mechanical shutter.

- Progressive scan CCD eliminates interlace deterioration of image and increases ease of

computer interface.

- High sensitivity and low noise during fast scanning. The CCD has an excellent S/N ratio at

the default setting that is greater than 58dB.

- The CCD has a built-in microlens for increased quantum efficiency.

• Electronic shutter

The TM-4200GE has a substrate drain-type shutter mechanism which provides superb pictures at

various speeds without smearing. For more information, please see Section 9.3 on page 63.

• Asynchronous reset

The TM-4200GE captures async reset images and provides single-shot video output with single

FDV (frame data valid). This makes it simpler for an ordinary frame grabber to capture the

asynchronous reset images. The TM-4200GE’s asynchronous reset is flexible and accepts external

horizontal drive (HD) for phase locking. When the VINIT (5V) pulse is applied to CC1, it resets the

camera's scanning and purging of the CCD.

The TM-4200GE has three modes to control the asynchronous reset and shutter speed:

- Async, no shutter. The video signal and FDV are reset by external VINIT.

- Internal shutter speed control. The speed control varies from 1/60 to 1/16,000 sec. The

video signal and FDV starts with internal V reset timing related to shutter speed.

- External VINIT with pulse width. The duration between pulse edges controls the shutter

speed externally.

• Output

The TM-4200GE has a dual-tap 10-bit/8-bit Gigabit Ethernet output.

• Dual-channel auto black level balancing and semi-auto gain balancing

The TM-4200GE, as a dual-tap output camera, has auto black level balancing and semi-auto gain

balancing functions.

• Warranty

Please contact your factory representative for details about the warranty.
