I really feel a personal need to tell you frankly how pleasant it is to work with you. I know that's how it should be, but believe me, it's no longer a matter of course.


Manfred Skibba


Your range is so good and extensive, even for small quantities, and the delivery is very fast and complete. So unfortunately I can't make any suggestions for improvement at the moment. Thank you and keep up the good work.

SATIP SRL


Woundable company, received commercially hard to find Harting plugs due to the war and other circumstances, in 36 hours to Italy, with a nice chocolate gift in the box.

Harting connectors

Harting connectors are a synonym for the industry standard in the area of heavy-duty connectors. They can be used flexibly and are always used whenever high reliability is required, even under high loads. Harting industrial connectors securely and powerfully fulfil their task. From a basic switch cabinet in the workshop, to connectors in vehicles and applications under extreme loads in industrial facilities or wind farms. Whether Han Modular, Harting Han 3A or Harting tool – we have got it for you.

✓ Available individually, now from stock
✓ No minimum order value
✓ Harting KIT available from stock
✓ Individual sets according to your requirements (e.g.: Housing, application, contact, etc.)
✓ Harting special housing. Custom-fit. Lead time 1 working day

Amphenol connectors

Amphenol connectors are used in data and signal transmission, outside and for high voltage applications. The housings are shaped either circular (Amphenol ecomate series) or rectangular (Amphenol A series) and metal or plastic. Apart from housings and contacts, our product range includes assembled Amphenol connectors in a set. These sets comprise a housing, various contact inserts and a related retaining wedge. Amphenol connectors are the cost-effective alternatives to Deutsch connectors from TE.

✓ No packaging units, no minimum quantities
✓ No minimum order value
✓ 100% compatible with Deutsch connectors
✓ Roller contacts individually from stock
✓ Bagged sets with connector and matching contacts

Circular connectors
Circular connectors are primarily used in measurement technology, control technology and regulation technology and in automation and mechanical engineering. Circular connectors available in sizes M12, M16, M17, M23, M40, M58, 7/8”, R15 and RD24. They are used in industrial electronics. Of course, we also have in stock the crimp contacts needed for the respective connectors.

✓ No packaging units, no minimum quantity
✓ No minimum order value
✓ Bagged sets with connector and matching contacts

Cables & Wires

Only high-quality cables and wires guarantee reliable electrical connections for machinery and equipment. Our product range includes control cables, single core cables, data lines to rubber cables. A broad product spectrum for every application area.

✓ By metre from stock
✓ Free cutting to length from 1m
✓ No packaging units, no minimum quantity


Electrical conduits

Electrical conduits are used wherever cables and wires need to be bundled and protected. Whether braided sleeving, protective metal conduit or split corrugated tube. Selection of the right protective tube depends on the respective application. Protective tubes reliably shield cables and wires from the effects of electromagnetic compatibility (EMC). They protect against mechanical, chemical and thermal environmental influences.

✓ By metre from stock
✓ Over 1000 cable drums for protective tubes
✓ Matching connectors individually from stock
✓ No minimum order value


Sensor / Ethernet / Bus

Industry places high demands on secure data transmission. Network connectors, patch cables, sensor connectors, sensor wires and network cables, as well as the matching connection technologies are important interfaces. Network components must also ensure loss-free information exchange under strong electromagnetic influences, extreme ambient temperatures, dirt, water and vibrations.

✓ By metre or individually from stock
✓ No packaging units, no minimum quantity
✓ No minimum order value


Cable glands

A cable gland must be reliable and secure. The focus must always be on the protection of people and objects, for example against radiation or explosion. Apart from the traditional use in switch cabinets and on housings, the cable gland and cable entry are used wherever cables must be fixed, inserted and sealed. A distinction is made between the metric cable gland, i.e. with a metric thread (M), and the PG cable glands, i.e. the steel conduit thread.

✓ No packaging units, no minimum quantity
✓ No minimum order value


Signal towers / signal lights

The signal towers and signal lights are ideally suited for monitoring processes, e.g. in production, and for displaying possible malfunctions through optical and acoustic signals. Especially for automated processes on machines, this signal technology can monitor complex processes and serve as a warning system in the event of malfunctions. Our range includes a large selection of modular signal towers and signal lights in two different diameters.

✓ Unbeatable price thanks to our own production
✓ Modular system, complete signal towers can also be expanded at any time
✓ Fully pre-assembled with up to 10m of cable or for self-connection
✓ No packaging units, no minimum quantity
✓ 800 variants avalaible from stock.


Heat shrink tubing

The heat shrink tubing offers a flexible application for cable connectors or repairs to defective cables and is easy to use. For example, it can be used as protection for a connector fitted to a cable or to restore damaged cable isolation. Alongside the isolation, it also provides mechanical protection and prevents dirt. Thanks to the large palette of twelve different colours, the heat shrink tubing is also ideal for labelling. You can buy the heat shrink tubing from us in the practical heat shrink tubing Minibox, as heat shrink tubing by the metre or heat shrink tubing roll.

✓ Unbeatable price Minibox only € 2.99
✓ 20,000 boxes always available for delivery from stock
✓ Available as box / by the metre / in rolls
✓ No minimum order value
✓ No packaging units, no minimum quantity


Switch& Button

Switches and buttons comprise command and signalling devices and the matching contact blocks. The switches and buttons, in assembled housings and panel mount jacks, perform central functions in the circuits of machines and equipment. They are used in safety areas, for example, as red-yellow emergency stop switches.

✓ Free technical advice
✓ No packaging units, no minimum quantity
✓ Available individually from stock


Switch cabinet accessories

The terminal blocks in the switch cabinet are space-saving and clearly installed next to each other on top-hat rails. This advantage of this arrangement is that individual terminal blocks can be easily removed and replaced. Individual terminal blocks can be easily connected together using jumpers. With the unique terminal block system from Phoenix Contact you can choose between connection terminals: Screw connection terminals UT and Push-In® connection terminals PT.
