The MICROSENS MS650505PM-48 is a 6-port Industrial Ethernet switch from the Profi Line, specifically designed for use in industrial environments. It features two 100FX ST/SM fiber connections with a range of up to 15 km, four 10/100TX PoE ports, and two 48VDC connections. The switch is a managed device and enables network management via an integrated RC function. It is designed for DIN rail mounting and is suitable for applications requiring a stable, reliable network connection under demanding conditions.

Industrial Networking

The switch is designed for use in industrial plants where high mechanical and electrical loads, temperature fluctuations, and electromagnetic interference may occur. The design meets the requirements for robust network components in production environments, such as in automation, manufacturing, or power supply. The integrated RC function enables remote control and monitoring of the device, simplifying maintenance and diagnostics during operation.

Functions and Equipment in Detail

The switch offers a total of six ports: two fiber connections (100FX ST/SM) with a maximum range of 15 km, suitable for long-distance connections, and four 10/100TX ports supporting PoE (Power over Ethernet). The PoE function allows power supply to end devices such as IP cameras, access points, or phones via the same network cable, simplifying installation and reducing the number of power supply cables. The two 48VDC connections serve as additional power input connections to increase the reliability of network infrastructure.

Technology Explained Simply

The fiber connections (100FX ST/SM) use single-mode fiber cables, suitable for high data transfer rates and long distances. The ST connector is a standard connection for industrial fiber cables. The 10/100TX ports support data rates of 10 or 100 Mbit/s and are equipped with PoE, enabling power delivery over the network cable. The 48VDC connections are intended for supplying the switch with direct current, which is common in industrial plants. The managed function allows configuration, monitoring, and control of the switch via network protocols, enabling centralized network management.

Compatibility and Accessories

The switch is designed for use with single-mode fiber cables (ST connector) and standardized Ethernet cables (Cat5e or higher) for the 10/100TX ports. The PoE function is compatible with devices supporting PoE standards (such as IEEE 802.3af or 802.3at). The RC function enables integration into higher-level control and monitoring systems. DIN rail mounting allows flexible installation in enclosures or control cabinets.

Mounting and Installation

The switch is mounted on a DIN rail, enabling standardized installation in industrial enclosures. Installation requires connecting the fiber and Ethernet ports to the corresponding cables and providing power via the 48VDC connections. The managed function requires a network connection to perform configuration and monitoring of the device. The RC function is intended for remote control and diagnostics.

Advantages in Operation

The switch provides a reliable network connection in industrial environments with high demands for stability and availability. The PoE function reduces the number of required power supply cables and simplifies installation of end devices. The fiber connections enable long reach and are immune to electromagnetic interference. The managed function and RC function allow centralized network management and remote monitoring, simplifying maintenance and fault diagnosis during operation. DIN rail mounting ensures flexible and standardized installation in existing enclosures.
