SIMATIC RF250R is a reader for operation with external antennas. Thanks to the different antenna designs (ANT 3, ANT 3S, ANT 8, ANT 12, ANT18 and ANT 30), the potential applications in the areas of tool identification and small assembly lines are extremely varied.

This reader has either

• an RS422 interface with 3964R transmission procedure for connection to RFID communication modules (see Communication modules),
• or an RS232 interface with ASCII protocol for connection to S7-1200, PC-based systems or third-party controllers,
• or a standardized IO-Link interface for connection to IO-Link Master modules from Siemens or third parties.

Thanks to its high degree of protection and rugged design, the SIMATIC RF250R reader enables problem-free use even under the toughest industrial conditions. Connection is made either with an 8-pin M12 plug-in connector (RS422/RS232 version) or a 4-pin M12 plug-in connector (IO-Link version).

The reader is operated with ISO 15693-compatible transponders.

Connectable antennas

One of each of the following antennas can be operated on a SIMATIC RF250R reader:

• ANT 3, due to its slimline, compact design, this antenna can still be precisely positioned even in cramped conditions. The dimensions are L x W x H (mm): 50 x 28 x 10.
• ANT 3S, same as ANT 3, except suitable exclusively for processing of MDS D117, MDS D127, MDS D421 and MDS D521 transponders. The dimensions are L x W x H (mm): 50 x 28 x 10.
• ANT 8, this cylindrical antenna is mainly intended for the field of tool identification. The extremely small design of the antenna enables extremely accurate positioning, dimensions O x L (mm) M8 x 38.
• ANT 12, universal round antenna in M12 design for assembly lines with extremely small workpiece holders, dimensions O x L (mm) M12 x 40.
• ANT 18, universal round antenna in M18 design for assembly lines with small workpiece holders, dimensions O x L (mm) M18 x 55.
• ANT 30, universal round antenna for assembly lines with small workpiece holders, dimensions O x L (mm) M30 x 58.
