The MICROSENS Industrial Fast Ethernet Switch, type MS657102PX, is a compact network switch for use in industrial environments. It features five ports: four 10/100Base-TX ports with integrated PoE+ (Power over Ethernet Plus) and one 100Base-FX multimode port with SC connector for fiber optic cables. The PoE+ function enables power supply to end devices such as IP cameras or access points via the network cable, with each port capable of delivering up to 30 watts. The operating voltage ranges from 48 to 56 volts DC, making it suitable for use with industrial power supplies. The switch is designed for operation in a temperature range of -40 to +75 degrees Celsius, making it suitable for harsh environments such as production halls, outdoor areas, or vehicles.

Applications

The switch is designed for industrial networks where high mechanical and thermal stress as well as reliable power supply for network devices are required. It is suitable for connecting surveillance cameras, industrial sensors, control systems, or communication devices in factories, logistics centers, or rail transport. The fiber optic interface enables stable data transmission over longer distances, with the multimode technology at 1310 nm wavelength optimized for short to medium distances.

Functions and Equipment in Detail

The switch offers four RJ45 ports with 10/100 Mbit/s data transfer speed, each equipped with PoE+. This enables simultaneous data and power transmission over a single Ethernet cable. The maximum power per port is 30 watts, sufficient to supply current PoE+-compatible devices. The fifth port is a 100Base-FX multimode fiber optic interface with SC connector, intended for connection to other network units via fiber optic cables. The operating voltage of 48 to 56 VDC is supplied via an external power supply connection, with voltage fluctuations within this range being tolerated.

Technology Explained Simply

The PoE+ technology (Power over Ethernet Plus) enables power supply to network devices via the existing Ethernet cable, eliminating the need for separate power lines. This reduces installation costs and simplifies device placement, especially in areas where direct power supply is not available. The 100Base-FX interface uses multimode fiber optic cables with a wavelength of 1310 nm, ensuring high data integrity over medium distances. The SC connector is a standardized, robust fiber optic connection commonly used in industrial applications. The operating temperature range of -40 to +75 °C demonstrates the device's high environmental resistance, ensuring reliable operation even under extreme temperatures.

Compatibility and Accessories

The switch is compatible with various power supplies operating in the 48 to 56 VDC range. Suitable accessories include, for example, power supply modules from MEAN WELL, such as the 48V 120W DIN rail model SDR-120-48 or the 48V 480W model SDR-480-48, suitable for mounting in enclosures. Additionally, a TP(RJ45) POE tester is available for checking PoE functions and network connections. These devices support installation and maintenance of the switch in industrial environments.

Mounting and Installation

The switch is designed for mounting on a DIN rail, enabling flexible and standardized installation in enclosures. The connection cables for the PoE+ ports are standard Ethernet cables (Cat5e or higher), while the fiber optic interface requires a multimode fiber optic cable with SC connector. Power supply is provided via an external power supply connection, connected to a suitable power supply in the voltage range of 48 to 56 VDC. Installation requires no additional tools, as DIN rail mounting allows for easy fixation.

Advantages in Operation

The switch provides a reliable network connection in harsh environments due to its robust construction and wide temperature range. The PoE+ function reduces the number of required cables and simplifies the installation of network devices. The fiber optic interface ensures stable, interference-free data transmission over longer distances, which is particularly advantageous in industrial applications. DIN rail mounting enables flexible placement in the enclosure, and the operating voltage of 48 to 56 VDC matches common industrial power supplies.
