Frequently bought together:


The Sentry Midrange II is the second generation of one of Vizinex’s most successful mount on metal RFID tags. The new generation tag provides the same excellent read range with an improved frequency response. This is in a package that is 30% smaller than the first generation tag with a price that is 25%. Now tracking valuable metal assets can be accomplished more cost-effectively than ever.

This tag has a remarkably small footprint of 39mm x 17mm. Despite this small package, it provides a read range of 25’ when mounted on metal. The smaller footprint and lower cost of the 2nd generation tag will enable the cost-effective tagging of a wide range of metal assets from reusable containers to oil field assets to construction equipment. The optional cover provides extra protection for the RF device, and the flexibility to use bolts, rivets or zip-ties for attachment. In addition to having an excellent read range, the Midrange provides strong response across the entire UHF band, so read rates are enhanced, even in tough, high metal environments.

The Midrange II will enhance the performance of asset management systems in industries already using the first generation tag, but will enable the economical tracking of a new, broader set of assets.

Like all Sentry branded products, the Midrange II is built on a robust platform that will tolerate repeated exposures to temperatures up to 170° C, vibration, impact and exposure to many chemicals. The uncovered tag boasts an IP rating of 68, and the covered tag is rated at IP69K.

The Midrange II is available in US or EU frequencies.
