Impact On The Transmission Window By Metal - Siemens SIMATIC RF 300 System Manual

Transponders which cannot be mounted directly on metal
Any transponder whose operation is interrupted by direct contact with metal cannot be mounted directly on metal. The
applicable minimum distance to metal must be maintained for the relevant transponder.

Impact on the transmission window by metal

In general, the following points should be considered when mounting RFID components:
• Direct mounting on metal is allowed only in the case of specially approved transponders.
• Flush-mounting of the components in metal reduces the field data; a test is
• When working inside the transmission window, it should be ensured that no metal rail (or

Mounting of a transponder on metal
with a non-metallic spacer
If the minimum guide values (a, h) are
not observed, a significant reduction of
the field data results. It is possible to
mount the transponder with metal
screws (M4 countersunk head
screws). This has no tangible impact
on the range.
