Siemens SCALANCE W746-1 6GK5746-1AA30-4AA0 IWLAN Client

Product Description

The Siemens SCALANCE W746-1 (6GK5746-1AA30-4AA0) is an industrial IWLAN Ethernet client module designed to integrate Ethernet-based automation devices into wireless LAN infrastructures. As part of the SCALANCE W700 portfolio, this device enables PLCs, operator panels, and industrial PCs to communicate over WLAN where cabling is impractical or cost-prohibitive.

This model is approved exclusively for operation within the United States and complies with regional radio regulations. It supports established IEEE 802.11 a/b/g/h standards and offers secure wireless communication using WPA2 and IEEE 802.11i mechanisms. Built for control cabinet installation, it features an IP30-rated enclosure, extended temperature tolerance, and industrial power supply options.

The SCALANCE W746-1 (6GK5746-1AA30-4AA0) is typically deployed in legacy automation systems requiring reliable wireless Ethernet connectivity without redesigning existing network architectures.

Functional Overview and Use Cases

Configured as a WLAN client, this device connects up to eight Ethernet-based end devices to a wireless infrastructure using NAT/PAT functionality. It is suitable for fixed industrial installations such as production cells, conveyor systems, and automated warehouses, where mobility is not required but wireless bridging reduces wiring complexity.

The module supports Power over Ethernet or a dedicated 24 V DC supply and provides external antenna connections for optimized radio performance inside industrial environments.
