Electromechanical connection technology
for defence, security and military technology.
Robust and safe to use
Components for
Safety-critical applications.
In the defence and security sector, electromechanical components must operate with absolute reliability under extreme mechanical, climatic, and electromagnetic stress. Whether for land, air, or naval operations, compliance with standards, long service life, and tested resilience ensure energy and data transmission in highly sensitive systems.
Our components are designed for the toughest operating conditions – from armoured vehicles and mobile command centres to complex radar systems and communication systems.

Since 1926 –
Connection technology for
Defence & Security.
As a German family-run company with almost 100 years of experience, we supply manufacturers, system integrators and direct customers in the defence and security sector with high-quality connectors, fasteners, cable protection and marking systems, and operating components.
We supply EMV-shielded solutions, high-strength connectors to VG and MIL-STD standards, and components with tested shock and vibration resistance for critical platforms.
Challenges
military operations.
- Shock and vibration loads from vehicles, weapon effects, or air operations
- Extreme temperatures from −55°C to +125°C
- Dust, sand, damp and saltwater
- Chemicals and fuel exposure
- Electromagnetic interference from radar, communication and electronic countermeasures
Important materials
for military technology.
-
Stainless steel (A4/V4A) – corrosion-resistant, for fastenings and housings
-
Nickel-plated brass – high EMC shielding, resistant to corrosion
-
PA66, PEEK – High-performance plastics with impact strength and chemical resistance
-
Halogen-free flame retardant materials – VG and MIL-STD compliant for fire protection

Electromechanical components –
for military technology.
Industrial connectors for
military deployment.
Connectors compliant with MIL-STD and VG standards, as well as IP protection ratings up to IP69K, offer reliable connections under extreme conditions. Ruggedised versions, along with push-pull, bayonet, and screw systems, withstand shock, vibration, and significant temperature fluctuations.
They are suitable for applications where reliability and robustness are crucial.
Cable protection systems for
Operational Equipment.
Metal-reinforced sheaths and abrasion-resistant braided hoses provide additional stability. This ensures that installations remain secure and durable, even under continuous load.
Cable labelling for
safety-critical systems
They are resistant to chemicals and weather and remain easy to read even under high stress. Various versions facilitate integration into different system environments.
Insulation sleeves &
Feed-through sleeves.
Different designs allow for precise adaptation to various installation requirements.
Fasteners
They are designed to be vibration-resistant and ensure reliable cable routing. Various designs support flexible applications.
Quality & Testing – certified
military components.
Reliability in operation begins with uncompromising quality assurance and standards-compliant manufacturing.
Our Standards and Examinations:
- ISO 9001 – Quality Management
- ISO 14001 – Environmental Management
- VG-Norm
- MIL-STD
- RoHS/REACH compliance
