We provide reliable connections

Connectors must ensure reliable transmission of energy and signals – coping with high voltages, harsh environments and the rough conditions of rail traffic. Connectors from Schaltbau are especially designed to meet theses requirements: Where safety and health of human beings are dependent on technology – as in transportation, mechanical engineering, lighting, food processing, battery charging, mining or offshore operations – the rugged heavy-duty connectors from Schaltbau are first choice.

Whether for railroads, charging stations of modern forklift fleets with lithium-ion batteries or control cabinets of supply and transformer stations – with Schaltbau Connections you stay connected to the most important OEMs of standardized hybrid cables for data, signal and power transmission. Because now the tried-and-tested, robust Schaltbau connectors for rail and industry are also available ready assembled. And just as you need your connector: with flexible standard cable, with special cable or cable according to customer requirements, ready-wired from a single source.

EP series - Connectors to UIC for electro-pneumatic brakes

This heavy-duty connector is designed to ensure the electrical connection within a train for the electro-pneumatic brakes (EP brakes) as well as the bypass of an electro-pneumatic emergency brake.
Both systems have functions which overlap through their control and monitoring elements. They are fed by a common electrical cable that runs the length of the train. Integrated in the receptacle is a switching element as pilot contact which is used for feedback signalling a plug being mated, whereas the end of train is signalled by means of a pin contact in the dummy receptacle. The connector is designed in accordance with the specifications of the international railway standard UIC 541-5 VE.

EP series to UIC 541-5 VE
  • Pre-assembled single and double ended connecting cables: Plug and receptacle without switching element coming with 9 core UIC compliant hybrid cable or 11 core cable for receptacle with switching element: No individual wiring of the 2 additional wires for the connection of the switching element and mounting of the protective hose that goes with them
  • Receptacle ready mounted on the angle plate with earthing connection and strain relief for direct mounting to the body of the car or for connection to junction boxes
  • Easy mounting and replacement
  • No costly tests as with individual wiring

UIC and UIC-IT series - Connectors to UIC for reliable data communications in trains

With their 8 pole Gigabit Ethernet module and optional 16 signal contacts, the rugged, durable UIC-IT Series connectors (yellow) stand for high transmission rates as required for today’s automatic passenger count systems and on-board video surveillance as well as on-board services for passengers, such as WiFi and multimedia. Schaltbau offers the right connector system for data communications which is likely to set a standard for data connections in railway vehicles.
Likewise, the connectors to UIC 558 VE (light grey) are also superbly suitable for binary data transmission, as for instance via CAN bus or WTB (wire train bus).

The rugged jumpers typically connect lines used for the remote control of lights and train doors or for public address systems in passenger coaches of trains or diesel and electric multiple units. The break-away connector ensures, provided the receptacle is installed in the correct position, a non-destructive separation of plug and receptacle when two electrically not decoupled vehicles move apart.

UIC and UIC-IT series
  • Pre-assembled single and double ended connecting cables for individual single conductors laid inside corrugated pipe or UIC-compliant hybrid cables
  • Complete sets for mounting of UIC series for direct mounting to the body of the car or for connection to junction boxes
  • Easy mounting and replacement
  • No costly test as with individual wiring

ZH series - Jumpers to UIC 552 for train lines

All rail vehicles equipped with a train line, such as trains and multiple units require jumpers to UIC 552. Jumpers provide the electrical connections between the locomotive and the carriages or between the motor cars and the not powered trailer cars of a multiple unit train.
The new ZS552 coupling receptacle now has a symmetrical design and a common terminal for connecting cables entering from the left, right or the rear. The insert can now be replaced from the front without the need of wiring any longer. And for maintenance an optional lock and key is available.
The seal and drainage of the lid have also been improved. Thus the new ZS552 receptacle will provide for more safety and handling comfort.

ZH series to UIC 552
  • Pre-assembled plugs: Single and double ended connecting cables
  • Non-halogen sheathed power supply line for rail vehicles: With improved flammability rating and heat resistance, following DIN VDE 0250-606 and DIN EN 50624, type designation NSHXAFCMOE 3,6/6 kV
  • Cables of different lengths and sizes
  • Wire gauge: 185 mm²
  • High voltage test up to 13 kV inclusive

B series - Connectors for multiple unit operation

With nominal voltages up to 600 V DC and 400 V AC, the B Series connectors are superbly suited for power and control circuits of road and rail vehicles alike.
To accommodate ridership railcars of public and private railway operators worldwide are usually coupled to form a consist of seven and even more cars. For operating such multiple units instead of the typical connectors to UIC the modular variants of the B Series are preferred for supplying energy and transmitting signals.
With layouts of up to 59+PE, the many control contacts make it possible to realise additional functions, such as an interlocking circuit to protect personnel against contact with live parts with a conductor.

B series for power and control circuits
  • Pre-assembled plugs: Single and double ended connecting cables
  • Cables of different lengths and sizes: Individual cables laid inside corrugated pipe, hybrid cables and pre-assembled to customer requirements
  • Modular design with layouts up to 59+PE

LV series - Charging connectors for battery storage systems

Plug & play storage systems for traction batteries of today’s forklift fleets consist of three parts: software-supported charger, battery and a charging plug as offered by Schaltbau, complete with special adapters for electrolyte circulation and automatic water top up systems. An optional pilot contact is available for use with charge control, thus assuring safe charge termination even if the plug is pulled prematurely. It also reduces contact wear and protects the user from electric shock.
Schaltbau charging connectors are available for use with charging stations in the power range of 1 kW up to 16 kW and for volt- ages ranging from 250 VAC to 400 VAC – preassembled with cables of different lengths and terminal lugs.

LV for faster charging
  • Pre-assembled weld cables with sizes up to 4/0 AWG
  • Cable lugs and terminal lugs with sleeves, such as the ones from Flex or Perfect, specially designed for use with batteries
  • Optional snap-on adapter suitable for holding up to 4 additional signal contacts. With them it is easy to establish the Bus/CAN connection needed for the charging management of modern li-ion batteries
  • Fast charging capacity up to 500 A
  • High-quality screw-machine power contacts
  • Adapters for use with electrolyte circulation and water top up systems
  • Optional pilot and auxiliary contacts

G series - Connectors for switchgear cabinets of utilities

Extension or refurbishment of switchgear for medium voltage transformers usually results in more wiring also, because more signals, for instance, have to be added to the signal cabinet. And here the rugged G Series industry connectors from Schaltbau come in handy, because with layouts ranging from 4 pole up to 32+PE, the connector series offers all the flexibility which is needed to fit the purpose.
Schaltbau Connections now makes it possible that energy supply companies order as a set the connectors pre-assembled with just the kind of cables, lengths and terminal ends they need. The direct benefit is a reduced wiring effort and no acceptance testing at the end of it.

G series rugged industry connectors
  • Receptacles, pre-assembled with individual cables
  • Plugs, pre-assembled with hybrid cables Type YY (F) 0,6/1 kV – flexible PVC control cable
  • Connectors meeting the requirements as specified for switchgear cabinets of utilities
