For example, a handheld scanner with a large detection area and a long reading distance is effective at reading barcodes and 2D codes at manufacturing sites. The required performance varies depending on the application and also on whether the codes to read are just barcodes (1D codes), just 2D codes, or both. You can improve your work efficiency by selecting the handheld scanner that matches your specific purpose, considering factors such as scan speed, response, detection area size, sharpness, and distance to the target.īecause they are simple devices, one of the factors for selecting handheld scanners is their advanced performance matching various applications. Handheld scanners provide substantial performance as devices specialized for reading while held by the operator. Handheld scanners can be used in a variety of situations such as manufacturing sites, logistics warehouses, retail stores, medical institutions, infrastructure, and amusement facilities, and selecting the scanner specialized for the codes to read leads to improved work efficiency.īenefit 2 of handheld scanners: Specialized machine performance such as response and high-speed reading The codes of various standards can be read and arbitrary items of, for example, work systems can be entered. On the other hand, handheld scanners specialized for code reading simplify hardware configurations and improve work efficiency with their compact and lightweight designs that provide excellent ease of handling in reading work. There are also handheld computers used as handheld type reading devices, but using these multi-function handheld computers close to PCs, PLCs (sequencers), and similar devices complicates the system and work. Handheld scanners specialized for ease of handling and advanced reading performance are effective at improving work efficiency when connected directly to a PC, PLC, POS register, or similar device. Handheld scanners are used to read barcodes, 2D codes, or both. This information is also transmitted and applied to POS systems and similar systems via in-store POS registers. The read information is transmitted and applied to software or a connected work system for production or inventory control via a connected PC, PLC, or other such device. In most situations, handheld scanners are held in a single hand when used, but they may also be used in a hands-free orientation where they are mounted on a stand to read targets as they pass by. Therefore, handheld scanners are normally operated with a simple mechanism such as a trigger switch or button. Also, the purpose of handheld scanners is to transmit the read information to the connected device or software without using a terminal to perform programming or write information for the work application, which is different from handheld computers. Therefore, most handheld scanners are smaller and lighter than other reading devices to prioritize ease of handling during work. The target is exposed to a laser or LED, and the reflected light is received by a CMOS or CCD to read the code.Ī diverse variety of reading devices including fixed mount code readers and handheld computers is available, but the major difference between these devices and handheld scanners is that the latter is specialized for reading codes with the scanner held in the operator’s hands. Other scanners support the reading of both barcodes and 2D codes. Some scanners are specialized for reading barcodes. KEYENCE handheld scanners can be held in a single hand to read barcodes and 2D codes and import information into PCs and similar devices.
