Hirschmann

K2 Automation sources, supplies, and repairs Hirschmann industrial networking hardware, covering DIN-rail and 19-inch rackmount Ethernet switches, SFP transceivers, media modules, and power supply units used in control cabinets, substations, trackside enclosures, and process plants.

As an independent sourcing specialist, we supply new, refurbished, and obsolete Hirschmann stock, and repair failed units where no replacement is available, so sourcing and repair are handled through the same enquiry.

Sourced, Supplied, and Repaired by K2 Automation

We hold and source from a catalogue of more than 300,000 new, refurbished, and obsolete parts, backed by a global network of specialists and repair centres. We have supplied industrial automation hardware for over 12 years, and every item we ship or repair carries a 12-month extendable warranty.

We work on an enquiry basis rather than a public checkout. Add what you need from our Hirschmann range to your Enquiry List, and a dedicated account manager will confirm availability, condition, lead time, repair options, and price for your exact part number. We are an independent specialist, not an authorised Hirschmann or Belden distributor; all trademarks remain the property of their respective owners.

Hirschmann Automation and Control

Hirschmann Automation and Control GmbH is a German manufacturer of industrial networking hardware and has been part of Belden since 2007. Its focus has always been rugged Ethernet infrastructure rather than office networking, which is why the hardware turns up in rail trackside and rolling stock applications, substations, water treatment works, tunnels, ports, steel plants, and automotive body shops.

Engineers specify it for fanless convection cooling, conformal-coated electronics, redundant power inputs, and a service life measured in decades rather than product cycles, which is exactly why sourcing becomes difficult: installed units frequently outlive the catalogue that sold them.

Hirschmann Product Families Stocked and Sourced on Request

We quote across the full industrial networking portfolio, including legacy families withdrawn from the manufacturer’s catalogue:

• RS20, RS22, RS30, RS32, and RS40 compact DIN-rail switches for cabinet-mounted machine and process networks.
• MS20 and MS30 modular DIN-rail switches, with port count and media type set by media modules.
• RSR20 and RSR30 switches for substation and rolling stock duty, where EMC and temperature demands are tighter.
• MACH100, MACH1000, and MACH4000 19-inch rackmount switches for comms rooms, substation racks, and plant backbones.
• PowerMICE modular switches for higher-throughput ring and backbone segments.
• OCTOPUS IP67 field-mounted switches for mounting outside the cabinet, on machinery, or trackside.
• GREYHOUND high-performance switches for demanding backbone and substation networks.
• SFP and fibre transceivers, media modules, and replacement power supply units.

If a part number is not listed, send it anyway; unlisted, superseded, and end-of-life references are sourced through our specialist network on enquiry.

Managed and Unmanaged Switches, DIN-Rail and 19-Inch Rackmount Formats

An unmanaged Hirschmann switch forwards traffic on a plug-and-play segment with no configuration. A managed switch adds VLANs, QoS, port mirroring, SNMP monitoring, and ring redundancy, and is required wherever the network is segmented, monitored, or protected by a redundant topology. Swapping a managed unit for an unmanaged one will break a ring.

DIN-rail units mount inside control panels alongside the PLC and I/O, while 19-inch rackmount units sit in comms rooms and substation racks. Port configurations vary within a single family across copper, fibre, and mixed builds, and PoE and PoE+ variants power cameras, access points, and sensors directly from the switch. Input voltage and redundant feed arrangements differ, too, so match the power supply unit on replacement.

Redundancy, Operating Temperature, and Compliance Ratings

HIPER-Ring redundancy is the main reason a like-for-like replacement is usually safer than a substitution. The ring recovers quickly after a link failure, but recovery behaviour depends on the participating hardware, so check mixed-family rings against the manufacturer’s documentation before the unit goes in.

Hirschmann hardware also holds wide operating temperature ranges suited to unheated cabinets and trackside enclosures, plus the shock, vibration, and EMC approvals typical of rail and substation work, such as EN 50121-4 and IEC 61850-3 on the relevant variants. A commercial-grade switch in the same position usually fails validation on temperature, EMC immunity, or ring recovery time.

Obsolete and Discontinued Hirschmann Hardware Kept in Service

Many earlier RS, MS, MACH, and PowerMICE units are now end-of-life or withdrawn from the manufacturer’s catalogue, while the networks built around them remain in daily production. Plants keep them because a like-for-like unit avoids reconfiguring a validated ring topology, revalidating a safety case, or re-cabling a cabinet.

We source obsolete, discontinued, and reconditioned units through our global network of specialists, and every refurbished item is tested and condition-reported before you commit. Where no original exists, the options are a functionally equivalent successor family, a repair of your failed original, or a strategic spare held against future failure. The same cabinet often carries legacy PLC Systems that face identical obsolescence risks, so it is worth reviewing both together.

Fixed-Price Hirschmann Repairs on a No Fix, No Fee Basis

We repair failed Hirschmann switches at a fixed price quoted before work starts, on a no-fix, no-fee basis. If the unit cannot be brought back to specification, you pay nothing for the attempt.

The failures we see most often are power supply stages, dead copper ports, degraded SFP cages, and heat-related component damage in poorly ventilated cabinets. Repaired units are function-tested against original operating parameters before return and carry the same 12-month extendable warranty as supplied stock, with collection and return delivery arranged by your account manager.

How to Order Hirschmann Parts from K2 Automation

• Send the full part number and hardware revision from the housing label, or a photo of the label if the print is unreadable, as port and media combinations differ within the same family.
• Add the items to your Enquiry List, or request a quote directly for an urgent single line.
• Tell us whether the unit sits in a HIPER-Ring or managed configuration, so we can confirm the swap is valid.
• A dedicated account manager confirms availability, condition, lead time, repair options, and warranty.
• Consolidate anything else needed from the same panel, including HMIs and Displays or Safety and General Automation items, into one quote.

Hirschmann Parts: FAQs

Who makes Hirschmann switches?

Hirschmann industrial switches are made by Hirschmann Automation and Control GmbH, a German manufacturer that has been part of Belden since 2007. The brand covers rugged DIN-rail and rackmount Ethernet hardware for industrial, rail, and substation networks, and is separate from Hirschmann Automotive.

What is the difference between the Hirschmann RS20, RS30, and RS40 series?

All three are compact DIN-rail switches. The RS20 is the entry-level managed or unmanaged option; the RS30 offers higher port counts with gigabit uplinks; and the RS40 provides gigabit ports throughout. Exact media, port, and temperature specifications vary by individual part number.

Are obsolete or discontinued Hirschmann switches still available?

Yes. Withdrawn RS, MS, MACH, and PowerMICE part numbers are still obtainable as new surplus, refurbished, or reconditioned stock through independent specialists. We source them through our global network, perform condition testing, and can supply a repaired original if no unit exists.

What is a Hirschmann-managed switch used for?

A managed switch is used where the network needs configuration and visibility: VLAN segmentation, QoS prioritisation, SNMP monitoring, port mirroring, and HIPER-Ring redundancy. It suits plant backbones, substation networks, and any topology where a single link failure must not stop production.

Can K2 Automation supply or repair obsolete Hirschmann parts?

Yes. We supply new, refurbished, and obsolete Hirschmann hardware from a catalogue of over 300,000 parts, and repair failed units at a fixed price on a no-fix, no-fee basis. Supplied and repaired items carry a 12-month extendable warranty.
