Connection technology – precisely fitting connectors for your components.


Pre-assembled connections in all protection classes, connection types and cable versions.

Reliable connection technology minimizes error sources during commissioning and ongoing operation of your system. It must be designed to be resistant to media, have the appropriate design and all the necessary country certifications. In addition, the often extreme operating conditions demand specific protection classes (at least IP67) and where necessary, drag chain suitability.

As an experienced components dealer and hydraulics specialist, we offer a comprehensive, high-availability brand range of M8 and M12 connectors, circular connectors, valve connectors, adapters and connecting lines. Connection technology can be pre-assembled with the necessary cable types and in variable cable lengths depending on the application. Shielded or unshielded versions are also available, as are connectors with protective circuit and status LEDs.

M8 and M12 connectors / round connectors / valve connectors

Pre-assembled round connectors and valve connectors provide a tight and fast connection of sensors and actuators in industrial fluid technology. Their benefits are the low susceptibility to errors and the flexible application possibilities. When selecting circular connectors or valve connectors, it is important to consider the correct cross-section, cable length, design and type of connection as well as electrical, mechanical or thermal requirements.  

  • Design / cable outlet: straight connectors, angled connectors, T-connectors, Y-connectors
  • Connecting threads: M8, M12, M16, 7/8“, RJ45 etc.
  • Connection cross-section: 0.4 to 1.5 mm2
  • Temperature ranges: from -25 °C to +80 °C
  • Designs: shielded or unshielded, can be individually assembled, from protection class IP67, with LED, with protective circuit (for valve connectors)

Self-connecting connectors for on-site installation

Self-connecting circular connectors and valve connectors offer user-friendly interchangeability and enormous flexibility with regard to the connecting cable. Due to the simple construction and excellent assembly properties, the connection technology can be assembled quickly and effortlessly with respect to cable length and design. Design, cross-section and material resistance define the selection of the connection technology.

  • Design / cable outlet: straight connectors and angled connectors for on-site mounting
  • Connection technology: Solder connection, screw clamping technology, insulation displacement technology, crimp connection
  • Connecting threads: M8, M12, 7/8“, M16, M23, RJ45 
  • Connection cross-section: 0.4 to 1.5 mm2
  • Temperature ranges: from -25 °C to +80 °C
  • Versions: shielded and unshielded, matched to sensor and actuator lines, without pre-assembled cable, as of protection class IP67, with LED, with protective circuit (for valve connectors)
Connection lines

Connection lines and adapters

Pre-assembled connection lines allow the connection of sensors or actuators to the control periphery in the field or the direct connection of sensors to intelligent actuators (e.g. control valves). The main application areas for connecting lines are servo-hydraulic systems and analog control systems. In addition to the appropriate cable accessories, we supply all cables pre-assembled according to your requirements with the required cable lengths. 

Adapters and T-pieces for connectors provide the necessary flexibility in all electrical installations. They allow the practical, tight connection of different connection threads and are available in many combinations – e.g. as circular connectors M8 to M12 or RJ45 to M12. T-pieces are used, for example, for splitting digital sensor signals. The design and connection type must be precisely matched to your requirements.

  • Designs / cable outlet: Connection lines with straight or angled plug, adapter as Y-distributor, etc.
  • Connection thread, e.g. M8, M12, M16, 7/8", RJ45 etc.
  • Connection cross-section: 0.4 to 1.5 mm²
  • Temperature ranges: from -25 °C to +80 °C
  • Versions: shielded and unshielded, with various cable lengths, protection class IP67, various media resistances and drag chain suitability as required.


All common connectors and adapters, high availability and quick delivery.

There are many reasons to order your connection techniques directly from an experienced hydraulic specialist. The first is the individual and competent support.

Comprehensive range of connection technology from original

equipment manufacturers
System-compatible connections from quality-oriented brand manufacturers such as MURR, ifm, Bosch Rexroth, MOOG or Knoll Hydraulik.

In the correct protection category

All plug connectors, connection cables and connection lines are available in protection class IP67 and higher. The degree of protection specifies the suitability of electrical equipment for various ambient conditions. 


Our plugs and connectors comply with DIN EN 175301-803 and the standard specifications for the respective design (e.g. DIN EN 61076-2-101 for M12), the regulations for current stability according to DIN VDE 0298-4 and have all relevant certifications (UL, CSA and CE conform).
