Industry Leading Data Terminal with New Enhancements

The PDT 3146 from Symbol Technologies is the bar code data capture industry's most popular portable data terminal with a proven history of performance and reliability second to none. A wide variety of flexible options – including a choice of displays, keypads, bar code scanning and communications – enable the PDT 3146 to be customized to best fit the needs of your application. Users can select from 4- or 8-line by 20 character displays, 35- or 46-key alphanumeric keypads, optional integrated 1-D scanning, and either batch or wireless communications via Symbol's Spectrum24® wireless LAN technology. An improved display is sharper and easier to read, even in bright light. And a new and improved scan engine delivers robust scanning performance.

High Performance First-Time Every-Time Scanning

The PDT 3146 Series offers outstanding scanning for the most demanding environments. The SE1200 HP scan engine delivers faster scanning with the ability to easily read bar codes through plastic and other protective coatings, poor quality bar codes, and reflective and low-contrast symbols as well. In addition, the flexible scan head can rotate, enabling left- or right-handed scanning.

Ideal for Data-Intensive Applications

The PDT 3146 Series is ideal for data-intensive applications in a wide range of industries including retail, where portable data terminals bring increased efficiency and accuracy to shelf price audits, price checking, order entry, inventory control, shipping, picking and receiving. In transportation and logistics environments, the PDT 3146 enables more efficient package/baggage tracking, picking and receiving, and cross-dock applications.

Proven Past, Unlimited Future
