6GT2821-2AC10, Siemens, RFID reader, Compact reader Simatic RF210R, RS422, with integrated antenna

6GT2821-2AC10 is a RFID reader made by Siemens. This page describes a specific order variant, not just a general product line.

In industrial automation the exact order code is essential: similar-looking variants may differ in contacts, operating element, degree of protection, electrical parameters or compatibility. Catalogue parameters, recommended use and checkpoints before ordering are therefore listed separately below.

Operating principle

An RFID system identifies a transponder contactlessly by means of radio communication between the reader and the data carrier.

Typical applications

Used for identification of products, carriers, fixtures and material in production and logistics.

Technical specifications

Mounting and wiring

During installation, observe the reading distance, antenna orientation, surrounding metal structures and the correct communication interface.

Before commissioning, check the mechanical operation, electrical function and secure fastening. When replacing an original part, also compare the orientation of the cable, connector or actuator and the available mounting space.

How to choose the right variant

Compare the operating frequency or standard of the transponder, the interface, the range and the compatibility of the reader with the higher-level system.

Compatibility and replacement

When replacing, compare the original order code, contact function, mechanical design, degree of protection and electrical load. For accessories, the exact compatible series must also be verified. If a parameter is not stated in the available source data, it is not assumed in this description.

Operation, inspection and service

Check the mechanical mounting, cleanliness of the reading surface and stability of communication with the transponders.

After replacement or a change of mechanical setting, always carry out a functional test in the real working range of the machine. For elements that affect stopping or interlocking of the machine, also test the related control logic.

Source of technical data

The technical data in this description are based on the e-shop source export. The EMAS catalogue does not cover this product, so no unverified parameters have been added.

The catalogue and source text was used for the parameters of the specific variant. Technical values not documented in the available sources are not added to the description.

FAQ

What kind of product is 6GT2821-2AC10?
6GT2821-2AC10 is an RFID reader made by Siemens. The exact design and parameters of this variant are listed in the technical table.

How to verify that 6GT2821-2AC10 is the correct variant?
Compare the complete order number, product function, mechanical design, electrical parameters and compatibility with the specific assembly.

Why is a similar appearance or name not enough?
For industrial components, a small change in the code can mean a different contact, actuator, voltage, connector or a different function.

What should be checked before ordering?
Order code, contacts, mechanical design, degree of protection, electrical parameters and connection method. For accessories also the compatible series.

How to proceed when replacing the original part?
First copy the complete code of the original part. Then compare the function, dimensions, wiring and mechanical method of operation.

Can the product be used in another application?
Yes, but only if the technical and mechanical conditions match. The same product line by itself does not guarantee interchangeability.

What affects the reading distance?
Transponder type, antenna size, orientation, surrounding metal and the specific mounting conditions.

How to verify compatibility of the transponder and the reader?
Compare the RFID standard used, the frequency and the supported types of data carriers.

Can RFID be used on metal?
Only with a transponder and mounting designed for a metal surface, if the specific variant supports it.

What to check when connecting to a PLC?
Communication interface, addressing and compatibility of the communication module or higher-level system.
