The MICROSENS MS650502M is a managed industrial switch with six ports, specifically designed for use in demanding environments such as production facilities, factories or industrial networks. The device features four 10/100Base-TX ports, which are connected via RJ45 connectors, as well as two 100Base-FX SC multimode ports with a wavelength of 1300 nm, operated via SC duplex connectors. The ring function enables a redundant network structure, ensuring rapid restoration of data transmission in case of a connection failure. The switch is designed for operation with a 24VDC power supply and can be mounted on a DIN rail, making it suitable for use in enclosures or industrial control systems.

Applications

The switch is designed for industrial networks where high reliability, stability and operational safety are required. It is particularly suitable for applications in automation technology, including networking of controls, sensors, actuators and other field devices. The integrated ring function supports the creation of redundant network topologies, which automatically switch over in case of a connection failure to ensure network connectivity. The use of multimode fiber cables via SC connectors enables flexible integration into existing fiber networks.

Functions and equipment in detail

The switch offers a total of six connection options: four RJ45 ports for copper cables (10/100Base-TX) and two SC duplex ports for multimode fiber cables (100Base-FX, 1300 nm). The RJ45 ports support data rates of 10 or 100 Mbit/s and are suitable for connecting PCs, printers, switches or other Ethernet devices. The fiber ports enable transmission over longer distances with high bandwidth and are immune to electromagnetic interference. The ring function (RC) ensures rapid fault detection and recovery in the network, minimizing downtime. Device management is performed via a managed interface, enabling configuration, monitoring and control of the switch.

Technology explained simply

The term Fast Ethernet refers to a data transfer rate of up to 100 Mbit/s, which is sufficient for many industrial applications. The 10/100Base-TX ports use twisted-pair cables (e.g. Cat5e or Cat6) and are suitable for short to medium distances. The 100Base-FX SC multimode ports use multimode fiber cables, which offer greater reach and better resistance to interference. The wavelength of 1300 nm is typical for multimode fiber cables and enables efficient data transmission. The ring function (RC) is a protocol for network redundancy that automatically activates an alternative route in case of a connection failure. The managed function means that the switch can be configured and monitored via an interface (e.g. web interface, SNMP).

Compatibility and accessories

The switch is compatible with various power supply options designed for operation with a 48V-DC power supply. Suitable accessories include power supplies from the brand MEAN WELL, such as the SDR-480-48 (480W), SDR-120-48 (120W) and SDR-240-48 (240W) models, all designed for mounting on a DIN rail. These power supplies can be used to power the switch, provided the voltage specifications match. The use of an appropriate power supply is necessary to ensure reliable operation of the device.

Mounting and installation

The switch is designed for mounting on a DIN rail, enabling easy installation in enclosures or control cabinets. Power supply is provided via two separate connections, each of which can be connected to a 24VDC source to ensure redundant power supply. The connections are designed for use with plug connectors. The RJ45 and SC ports are located on the front of the device, allowing for easy cabling. Device management is performed via a network interface, which is connected to a computer or management system using an Ethernet cable.

Advantages in operation

The switch offers high operational safety through the integrated ring function, which automatically activates a redundant route in case of a connection failure. The use of fiber cables (SC duplex, multimode) ensures high resistance to interference and enables data transmission over long distances. The managed function enables centralized network management, making configuration, monitoring and fault resolution more efficient. DIN rail mounting and redundant power supply via two connections increase flexibility and reliability in industrial applications.
