The MICROSENS MS657104PX is an industrial network switch with five ports, specifically designed for use in demanding environments. It is a 5-port FE Industrial Entry Line switch with PoE+ functionality, featuring one 100FX SC/SM fiber optic port and four 10/100TX PoE+ Ethernet ports. The switch is designed for DIN rail mounting and is suitable for industrial applications requiring high temperature resistance and reliability. It operates in a temperature range of -40 °C to +75 °C and is powered by a DC voltage of 48 to 56 VDC. An integrated reset button (1x RC) allows for manual device restoration if required.

Applications

The switch is designed for use in industrial networks, particularly in environments with high mechanical, thermal, or electrical stress. Typical application scenarios include production facilities, power supply systems, transportation technology, or building automation, where a stable and low-maintenance network connection is required. The fiber optic connection via SC/SM connectors enables reliable data transmission over long distances, for example, between different production areas or between central units and peripheral devices.

Functions and Equipment in Detail

The switch features a fiber optic port (100FX SC/SM) designed for data transmission over fiber optic cables. This port supports a data transfer rate of 100 Mbit/s and is optimized for single-mode fiber (SM), ensuring high reach and minimal signal loss. The four Ethernet ports support data rates of 10/100 Mbit/s and are equipped with PoE+ (Power over Ethernet Plus). This allows power supply to end devices such as IP cameras, access points, or industrial sensors via the network cable, eliminating the need for separate power sources. The PoE+ technology provides a maximum power consumption of up to 30 W per port, sufficient to operate many industrial devices.

Technology Explained Simply

The switch operates according to the Fast Ethernet (FE) standard, meaning a maximum data rate of 100 Mbit/s per port. The PoE+ function uses the IEEE 802.3at standard protocol to transmit power and data over a single Ethernet cable. This reduces the number of cables and simplifies installation, especially in environments where laying additional power lines is difficult or costly. The fiber optic connection via SC/SM connectors offers high bandwidth and is immune to electromagnetic interference, making it suitable for critical industrial applications. The operating voltage of 48 to 56 VDC is typical for industrial systems and allows flexible integration into existing power supply networks.

Compatibility and Accessories

The switch is designed for DIN rail mounting, enabling easy installation in enclosures or control cabinets. The SC/SM fiber optic connector is standardized and compatible with corresponding fiber optic cables. The PoE+ ports are compatible with devices supporting the IEEE 802.3at standard protocol.

Mounting and Installation

Mounting is done via a DIN rail, typically found in industrial enclosures or control cabinets. Installation does not require special tools, but proper cabling is essential, especially when using fiber optic cables, to avoid signal loss. Power supply is provided via a DC voltage of 48 to 56 VDC, which must be supplied through the appropriate connection. The integrated reset button (RC) is used for manual device restoration in case of software or network faults.

Advantages in Operation

The switch offers high reliability due to its robust construction and wide operating temperature range of -40 °C to +75 °C. The PoE+ function reduces the number of required power supplies and simplifies network installation. The fiber optic connection enables stable and interference-free data transmission over long distances. DIN rail mounting facilitates integration into existing industrial infrastructures. The power supply via 48 to 56 VDC is compatible with many industrial power supply systems and allows flexible adaptation to existing installations.
