6GT2815-0BN40

What is this antenna cable used for?

It is a pre-assembled coaxial cable designed to connect a compatible UHF antenna to a SIMATIC RF600 reader in an industrial RFID system.

How long is the cable?

The cable has a total length of 40 metres, making it suitable for installations where the reader and antenna are positioned a considerable distance apart.

Which connector type is fitted?

Siemens 6GT2815-0BN40 has two straight RP-TNC female connectors, providing a ready-made connection between compatible RF600 readers and UHF antennas.

What is the cable impedance?

The cable has a nominal impedance of 50 ohms, which is standard for many industrial radio-frequency and RFID antenna connections.

How much signal attenuation does the cable introduce?

The complete 40-metre cable has a specified loss of approximately 5 dB. Its maximum attenuation per metre at 900 MHz is 0.13 dB.

Can cable loss affect RFID read and write performance?

Yes. Signal loss increases with cable length and can reduce the available power at the antenna, potentially decreasing read and write range. The correct cable-loss value should therefore be considered when configuring the reader.

Is the cable suitable for outdoor industrial installations?

The assembled cable is rated IP65 and has a PE outer sheath with resistance to UV exposure. Installation suitability should still be assessed against the environmental requirements of the complete system.

What temperatures can the cable withstand during operation?

Its specified operating temperature range is -40°C to +85°C. The permitted installation temperature range is -40°C to +80°C.

What is the minimum permitted bending radius?

The minimum radius for a single bend is 50 mm. Siemens RF600 antenna documentation specifies a 77 mm minimum radius where the cable is subjected to repeated bending.

Is this cable intended for continuous movement in a drag chain?

No. This version is intended primarily for fixed installations and is not identified as a drag-chain cable. A cable specifically rated for repeated flexing should be selected for continuously moving applications.

What materials are used in the cable construction?

The cable uses a copper inner conductor, a PE dielectric and a black PE outer sheath. Its shield is formed from braided, tin-plated copper wires.

Is the cable halogen-free and flame-resistant?

Yes. The cable is specified as halogen-free and uses an LMR-400-FR LSZH UL construction. The cable material is flame-resistant in accordance with UL/NEC and CSA CMR/FT4 requirements, excluding the fitted connectors.

What is the cable's outside diameter?

The outside diameter of the cable sheath is approximately 10.3 mm. This should be considered when selecting routing channels, glands, clamps and strain-relief components.

What strain relief should be provided during installation?

The cable should be secured close to the antenna connection so that its weight and movement do not place unnecessary strain on the antenna or connector. Suitable clamps should support the cable without crushing or sharply bending it.

What is the maximum operating voltage?

The specified maximum operating voltage is 2,000 V. In its intended application, however, the cable carries radio-frequency signals between the reader and antenna.

How much does the cable weigh?

The specified cable weight is 133 kg per kilometre. For a 40-metre length, the cable itself weighs approximately 5.32 kg before allowing for the fitted connectors.
