    Device-Prioritizing DIN-Rail-Mount Ethernet Switches

    Device-prioritizing Ethernet switches, also known as managed Ethernet switches, let you control which devices get priority speed on your network. For example, you can set it so that safety systems get all the bandwidth they need while they're running, and all other devices on the network share what's left over. Easily set up these switches over the web or via command line interface. No software required. Mount them onto a standard 35 mm DIN rail alongside PLCs, relays, and power supplies—they snap in place and stay secure.
    Ethernet switches connect computers, sensors, and other devices to the same network, so they can talk to each other, access the Internet, and provide you with real-time diagnostics. Switches are backward compatible, so they'll work in networks below their rated transmission speed. For example, a 100 Mbit/s switch will work in a 10 Mbit/s network, but it will only run at 10 Mbit/s.

    Ethernet switches with port mirroring allow any port on the switch to duplicate the output of another port. This is useful for troubleshooting network and performance issues.
    IEEE 802.1q—Ethernet switches that meet IEEE 802.1q standard for VLAN (Virtual Local Area Network) increase security, reliability, and efficiency by clustering devices on the network into groups. They also limit when and how devices can communicate outside of their group.

    Device-Prioritizing Rack-Mount Ethernet Switches

    Control which devices get priority speed on your network. Also known as managed Ethernet switches, these switches reduce network congestion so security, automation, and other critical systems have the bandwidth they need. Use them to create smaller networks called VLANs (Virtual Local Area Networks) to improve performance and limit user access to specific parts of the network. If you need to connect devices that don’t use Ethernet, these switches have two SFP (small form-factor pluggable) ports that let you plug in a transceiver or module.
    These switches mount into standard 19" wide racks, cabinets, and enclosures. To set them up, just enter their IP address into a web browser. They are backward compatible, so they'll work in networks below their rated transmission speed. That means a 100 Mbit/s switch will work in a 10 Mbit/s network, but it will only run at 10 Mbit/s.

    Switches with Power over Ethernet (PoE) can send both data and electricity to PoE-compatible devices, so you won’t have to run a separate power cord. If a device doesn’t support PoE, the switch only sends data to prevent damage. Their 30W output is often used to power advanced surveillance systems, wireless access points, and lighting.

    M12 connections instead of typical RJ45 keep out contaminants and won’t come loose from vibration.
    D—D-coded connectors are used for Ethernet rated up to Category 5 or 100 Mbps.
    X—X-coded connectors are used for high-speed Ethernet with data transfer rates up to 1 Gb/s.
    5-Pole M12—Switches with a 5-pole power plug have a ground pin.
    IEEE 802.1q—These switches use the IEEE 802.1q standard for VLAN (Virtual Local Area Network). VLAN increases security, reliability, and efficiency by clustering devices on the network into groups and limiting when and how devices can communicate outside of their group.
