Features
Scanning Performance
High-speed shutter and readability from any direction (360 degree)
You can improve your work efficiency by the high-speed shutter that enables operation not affected by camera shake, and readability from any direction.
Wide-angle scanning, improved readability
The number of horizontal pixels is increased and reading algorithms improved. Readability for wide barcodes used for public utility bills, medical bills, etc. is improved.
Improved resolution useful for various businesses
The newly developed reading engine enabled 0.125 mm resolution for 1D barcodes and 0.167 mm for 2D barcodes. The scanner can be used for a wide range of businesses such as operations of plants, hospitals and shops.
Multi-row barcodes can be read at one time.
The scanner can read two-row barcodes of books and up to three-row other barcodes. Decrease in the reading frequency can lead to drastic reduction in working hours.
Useful Functions
More efficient, more convenient
Possible to read barcodes on mobile phone LCD screen
The newly developed unique LED illumination control function is incorporated in the scanner to suppress specular reflection. The device can quickly read barcodes on mobile phone LCD screens.
Eye-friendly LED marker
In addition to the laser guide marker-type model, which is already on the market, the LED marker-type model that indicates the scanning area has been released. The scanner considers the safety of eyes, ideal for the use in service industries such as supermarkets.
Easy-to-use image capture function
The scanner can read not only barcodes but also take pictures. The device enables you to easily read even small characters. This function is useful particularly for logistics and transportation industries dealing with bills.(1)
- One JPEG image can be transferred within one second in the case of USB connection.
Incorporated with many user-friendly and unique functions of DENSO
The most lightweight device (approx. 110 g) in the class(1)
The most lightweight and compact design in the class results in less fatigue even after long working hours. Many other ideas are also incorporated into various parts of the body for usability.
Ability to withstand a 6.5 feet drop impact
In addition to the lightweight body, impact buffer materials and a highly durable case are used to possess the ability to withstand a 2-meter drop impact, the highest standard in the class. The device can also resist 100,000 drops from the height of 20 cm (7.9 inches), considering more ordinary troubles during actual use.
Smooth automatic scanning by attaching the scanner to a hands-free stand
The scanner can be used by holding it or by attaching it to a hands-free stand for scanning. You can use the scanner by setting it in the hands-free stand, or by holding the scanner when scanning a label attached to a large item.
The scanner can be used in more than 35 countries and regions.
DENSO group companies around the world can quickly meet customers' needs from sales to maintenance.
Areas where the AT20 series are available
Japan, EU (27 countries), US, Taiwan, South Korea, Australia, Thailand, Malaysia, Indonesia, Singapore, China
Configuration Software at Time of Introduction
Configuration software that lets you smoothly introduce the AT20Q.
Configuration Method 1
Upload all parameters at once as a batch operation from a PC via the COM port.
Configuration Method 2
Using the configuration software to output a batch configuration barcode, you can scan in all the parameters in one go with the AT20Q.
Comprehensive functionality that broadens the possibilities for scanning
Auto-sense mode
Because the AT20Q automatically detects when a label is placed in view and begins to scan it, it can really demonstrate its strengths in the workplace when attached to a stand for operation.
Data verifying function
The AT20Q includes Verifying functional that registers a master code and compares it to the scanning target.
Data editing functions
It accommodates simple programming functionality (ADF scripting), permitting many different operation control possibilities like data truncating and sorting.
Command control
The operational status of the scanner can be controlled with commands from a superordinate device.
Software trigger: turns scanning on or off.
Software trigger: turns scanning on or off.
| Primary command control examples | Descriptions |
