PROCON Rectangular connectors


PROCON electrical connectors are used to supply power and control, in measurement and control technology, as well as in mechanical and systems engineering. Lighting and stage technology also uses PROCON electrical connectors. At the same time, they also serve as interfaces for PCs or diagnostic equipment in order to transfer operating data or monitored information during system operation.

Rectangular shape for the best possible use of space


The footprint of the rectangular plug connections offers the best possible use of space for various contact arrangements, according to which the individual series are differentiated. The rectangular shape is also very easy to install and space-saving in machine recesses, sectional steel and on switching cabinet surfaces.

Signal and power transfer


The industrial plug connection range is made up of housings and inserts. Base, panel, grommet and coupling housing from the A3-A32 and B6-B48 series are available in aluminium, zinc and plastic. They can be equipped with various locking types (lateral, longitudinal and central locking).

The glass fiber-reinforced plastic inserts can accommodate 3 to 280 contacts and can be designed as crimp, screw, push-in or IDC connections. Depending on their use, special high-current, high-voltage or high-temperature inserts are available.

Up to 80A or 1,000 Volt can be transferred with modular inserts. The system also offers the option of using coaxial, RJ45, universal or professional bus and pneumatic modules.

Contact inserts


The contact inserts and contact carriers are made from glass fiber-reinforced plastic and can accommodate 3 to 280 contacts. They are suitable for temperature ranges from -40°C to +125°C (special design up to +180°C) and are differentiated in terms of their connection technology into crimp, screw, push-in and IDC connections.



Housings for all PROCON electrical connectors are made from die-cast aluminium, die-cast zinc and glass fiber-reinforced polyamide. A seawater-resistant special aluminum die-cast alloy is used for the BHT series. The aluminum housing is given a high-quality powder coating in grey for standard applications, black for increased environmental requirements (BHT series) and silver for electromagnetic compatibility.



Contacts are the core of any plug connection. Revolving machines automatically check each contact. Pins and sleeves are subjected to the most stringent quality checks. This guarantees consistently easy connection and disconnection for many years.

Modular system


The MO series represents a logical, user-focused further development of the PROCON electrical connector system. The advantage of this is the modularization of the insert. The conventional division into pin and socket contact inserts no longer applies here. The user has the option of inverse placement, i.e. a holder frame can accommodate both pin and socket contact carriers in a modular construction. 

PROCON One-Touch


The PROCON B6 Series "Easy Latch" connector, that can be used in applications where space is at a primium. For applications that require multiple connectors mounted in a "tight" space or closely together the PROCON "One-Touch" design is the perfect solution!
