HIRSCHMANN OS20-001200T5T5T5- TBBZ999HHNE3S 08.1.00 industrial switch

The Hirschmann OS20-001200T5T5T5-TBBZ999HHNE3S 08.1.00 (historically part of the OCTOPUS family) is an ultra-rugged, IP67-rated managed Industrial Ethernet switch. Engineered specifically for harsh environments outside the safety of control cabinets, it completely eliminates the need for protective enclosures.

Featuring vibration-proof M12 connectors and a sealed housing, it is designed to operate reliably under extreme physical stress, wet conditions, and wide temperature swings.

Technical Parameter List

The precise configuration of this switch is defined by its highly detailed product code structure:

Product Features & Core Advantages

Cabinet-Free Mounting (IP67): No cabinet needed. This switch can be bolted directly to machine frames, railway cars, or exterior walls, saving installation space and hardware costs.

Vibration-Proof M12 Connections: Standard RJ45 clips fail under mechanical vibration. The OS20’s threaded M12 connectors ensure gas-tight, locking physical connections that never shake loose.

Conformal Coated Internal PCBs: Treated with a specialty protective film, shielding internal circuits from condensation, micro-dust, salt spray, and corrosive atmospheres.

Advanced Redundancy Protocols: Supports MRP (Media Redundancy Protocol) and HIPER-Ring. Network recovery times are sub-80ms, ensuring automation processes keep running without interruption during a link failure.

Enterprise-Grade L2 Security: Outfitted with IEEE 802.1X port authentication, IP/MAC filtering, access control lists (ACLs), and secure HTTPS/SSH encryption.

Model Classification (OCTOPUS/OS Series)

Hirschmann’s IP67 portfolio divides into specialized subgroups depending on speed, PoE, and certification requirements:

OS20 (Standard Fast Ethernet): $10/100text{ Mbps}$ ports, optimized for standard PLC communication and device networking.

OS30 (Gigabit Ethernet): Equipped with $1000text{ Mbps}$ M12 ports for high-bandwidth uplinks, cameras, and data-heavy processing.

OCTOPUS PoE/PoE+ Series: Models designed to supply high-power Power over Ethernet directly to IP cameras, wireless access points, or badge scanners over a single M12 cable.

Transportation-Specific (Train/EN 50155): Specialized variants with specific fire protection and rolling stock approvals for rail mounting.

Environmental Tolerance Conditions

This switch is designed to thrive where standard hardware fails:

Operating Temperature: $-40text{ °C}$ to $+70text{ °C}$ cold-start and continuous operation.

Ingress Protection: IP67 (dust-tight and protected against water immersion up to 1 meter for 30 minutes).

Vibration Resistance: Certified to handle severe mechanical shock and vibration (IEC 60068-2-6 and IEC 60068-2-27 compliance).

Electromagnetic Compatibility (EMC): High immunity to electrostatic discharge (ESD), line surge, and magnetic fields typically found in heavy industrial environments.

Installation Method

Unlike cabinet-based switches, the OS20 features an integrated flat mounting flange.

1.Position and Screw Mount：Direct mounting。

Align the switch's integrated mounting flanges on a flat, rigid surface. Secure using four heavy-duty M6 screws to ensure high vibration resistance.

2.Establish Functional Grounding：EMC protection。

Connect a low-impedance ground strap from the designated grounding terminal on the switch housing directly to the machine's central ground point.

3.Wire M12 Power Inputs：Redundant 5-pin power。

Connect the dual DC power feeds to the 5-pin, A-coded M12 power plug. Screw the connector securely onto the switch interface to seal it.

4.Connect M12 D-Coded Ethernet Cables：Network connections。

Align and thread the 4-pin, D-coded M12 Ethernet patch cables into the ports. Ensure they are tightened completely to maintain the IP67 seal.

Operating Instructions

First-Time Configuration

Default IP Address: The switch is set to receive an IP via DHCP by default. If no DHCP server is present, configure a temporary static IP using the Hirschmann HiDiscovery software tool over the network.

Accessing the GUI: Enter the switch's IP address into a secure web browser (HTTPS). Log in using the default credentials found on the product's physical side-label.

Change Default Credentials: Upon initial login, you will be prompted to change the default admin password to secure the switch.
