IDTS-3511 UHF On-Metal RFID Tag - 35 x 11 mm PCB Screw-Mount Tag for Tools, Panels & Equipment

The IDTS-3511 is a slim passive UHF on-metal (anti-metal) RFID tag built on a black PCB substrate. It is a compact rectangular bar measuring 35 x 11 mm, with two through-holes for screw mounting, so it can be fixed permanently to metal assets that are handled or moved. Designed for asset registers that have to survive the shop floor, it delivers a read distance of approx. 4 m on metal and carries an operating temperature range of -20 C to +150 C.

Applications

• Tool crib and hand-tool control - spanners, torque tools, dies and small metal implements issued and returned across shifts
• Jigs, fixtures and moulds on manufacturing lines, where a narrow 35 x 11 mm bar fits on a machined face or bracket
• IT asset audits - server racks, switches, patch panels, metal cabinets and docking hardware
• Electrical panels and control cabinets in utilities, substations and plant maintenance rounds
• Valves, pipe brackets and small metal fittings tracked during preventive maintenance inspections
• Returnable metal trolleys, cages and stillages moving between warehouse, dispatch and customer sites
• Stainless equipment, trays and carts in pharma and food-grade production areas that need a screw-fixed identity plate

Why Choose This Tag

• Made to work on metal, not despite it. The anti-metal construction is intended for direct mounting on metal assets and gives a read distance of approx. 4 m on metal - enough for handheld audits down a rack row or a tool store aisle.
• Screw-fixed, not stuck on. Two through-holes of 3.2 mm diameter at 29 mm spacing, plus small plated corner holes, let you bolt the tag down permanently on assets that get handled, cleaned and moved constantly.
• Wide -20 C to +150 C operating range. The rated range covers cold stores at one end and hot machinery, motors and curing areas at the other, so one part number can cover very different parts of a plant.
• Standards-based data structure. ISO18000-6C with 128-bit EPC and 96-bit TID memory means it works with mainstream UHF readers and gives room to encode your own asset numbering scheme.
• Slim bar footprint. At 35 x 11 mm and 3.4 mm thick at its highest point, the tag suits narrow flanges, brackets and panel edges where a large on-metal tag simply will not sit.

Read range figures are typical and will vary with the reader and antenna used, transmit power, antenna orientation, the mounting surface and the surrounding environment. We recommend a short on-site trial with your own reader before large deployments.
