Crimp contacts,
Connectors and housings
Secure connection technology.
What are crimp terminals and
Connector systems?
Crimp contacts and connectors form the basis of every electrical connection. They ensure secure, vibration-proof, and durable contact between conductors, cables, and devices. In combination with matching housings, systems are created that range from simple cable connections to complex connector systems – robust, precise, and suitable for almost every industry.
Püplichhuisen offers a wide range of crimp contacts, connectors, housings and connection systems – from traditional flat-pin connectors to high-performance industrial connector systems.

Types and application of crimp contacts.
What are they?
Crimp contacts
in band format.
Contacts on reel are optimized for automated processing in crimping machines. They enable high volumes with consistent quality.
Norm tested for gas-tight crimped connections in accordance with DIN EN 60352-2.
Technical details: suitable for cross-sections from 0.08 mm² to 6 mm², up to 6,000 crimps/h with automatic machines.
Applications Series production, wiring harnesses in automotive, electrical appliance manufacturing, white goods, mechanical engineering, entire industry.
Crimp contacts
individually.
These contacts are processed manually or with semi-automatic machines. They offer flexibility for small series or repairs.
Norm also DIN EN 60352-2, ideal for small-batch production.
Technical details: Cross-sections from 0.25 mm² to 16 mm², high variety of options.
Applications Prototyp construction, maintenance, small series, bespoke solutions.
Types and Application of
Connectors & Housings.
Housing for
Connector systems.
The appropriate housings ensure mechanical stability, protection against environmental influences, and pole security. Available in plastic or metal, with protection classes up to IP69K.
Norm Enclosures to international standards such as IEC 60998/60999.
Applications Industrial automation, automotive, medical technology.
Complex connector systems
for industrial use.
Modular systems combine signals, data, and power in one housing. They offer EMC protection, interlocks, and high pole counts.
Norm frequently according to IEC 61076 for industrial applications.
Applications Manufacturing facilities, robotics, process automation.
Connector systems for
Commercial vehicles.
Particularly robust against vibration, temperature changes, moisture and dirt.
Norm developed to LV214 and USCAR-2, which define test procedures for automotive connectors.
Applications Lorries, buses, agricultural machinery, construction and special vehicles.
Flat plug technology
The spade terminal technique is one of the most widespread connection techniques. It is based on flat contact tongues and the corresponding socket terminals.
Norm regulated according to DIN 46340.
- 2.8 mm blade terminal technology

- Flat plug technology 6.3 mm
Applications Household appliances, vehicle manufacturing, control cabinet construction. Electronic assemblies, control units.
Flat plug technology With spring mechanism for particularly secure grip and vibration-resistant connection.
Circular plug technology
Bullet connectors and bullet sockets are based on round contact pins and sockets, offer low contact resistance, and are vibration-resistant.
Norm frequently according to IEC 61076.
2.0 mm round connector system Miniaturised system for tight installation spaces and signal transmission.
Applications Medical technology, electronics, sensor technology.
Claw cable lugs
GeneralCrimp connectors have integrated claws that further secure the cable.
- Ring terminal: Screw connection according to DIN EN 60999.
- Fork shape: quick insertion under screws, even with fixed installations.
Applications Control cabinet construction, plant engineering, vehicle technology.

FAQ: Frequently Asked Questions about
Crimp terminals, connectors
and casings.
What is the difference between flat and round connection technology?
Flat plug technology is compact and quickly connectable, while round plug technology offers lower contact resistances and greater vibration resistance.
When should you use claw-type cable lugs?
For vibrations or mechanical stress, when additional fixing is necessary.
What are the differences between crimp contacts in strip and loose-piece form?
Bandkontakte are optimised for machines, individual forms for flexible processing and smaller quantities.
How many mating cycles do blade terminals withstand?
Depending on the version, 50–500 cycles. Circular connector systems are suitable for frequent plugging and unplugging.
Which standards apply to connectors in the commercial vehicle sector?
Above all LV214 and USCAR-2, which govern load-bearing capacity, leak tightness and vibration resistance.
What is the difference between insulated and uninsulated crimp contacts?
Insulated contacts protect against short circuits and make handling easier; uninsulated ones are more compact and cheaper.
What are butt connectors used for?
To Extending or repairing cables, also protected against moisture with heat shrink tubing.
