MINIATURE F7 CONTACT
FOR MULTI & HYBRIDFIBRE OPTIC CONNECTORSMINIATURE FIBRE-OPTIC F7 CONTACT FOR MULTIFIBRE OR HYBRID OPTICAL/ELECTRICAL OF THE 1K-5K
AND 1B-5B SERIESIn addition to the existing F2 fibre optic contact shown in our catalogue of Fibre-Optic connectors No 5, the B and K
series can now also be fitted with the new miniature F7 contact. The main benefits of using this contact are:
– Reduced size allowing increased contact density. As an example, a 4-channel fibre optic connector is now possible inseries 3K/3B.
– Use of industry standard 1.25 mm diameter ferrule and polishing processes.
Contact design is based on the well-proven F2. Contacts fit onto buffered fibres or semitight jacket cables up to 2 mm indiameter.
This brochure shows only a sample of the available models of connectors. Refer to our catalogue No 5 for more detailed
information of the full range of LEMO fibre optic connectors. Refer also to catalogue No 5 for accessories or tools specific to the electrical contacts used in hybrid connectors.

F7 Fibre Optic Contact
Introduction
The F7 type contact is designed to fit multi fibre connectors or hybrid fibre optical/electrical connectors from 1B to 5B, 1K
to 5K series. The design is based on the well proven F2 contact.
Its main features are as follows:– Ceramic ferrules diameter 1.25 mm– Simple and fast polishing ensuring the physical contact of the fibre end face
– After mounting on the cable, the contact is very easily installed in the main connector insulator, the particular shape ofthe contact body retains it in the insulator– Single type of cable assembly, regardless of connector shell used
– The alignment tube can be easily removed in order to clean the fibre end face.
This contact makes it possible to use single fibre cables with single-mode or multi-mode fibres of the following sizes;
9/125, 50/125 and 62.5/125.

Insulators for 1B-5B and 1K-5K series vary according to
the fibre optic contact type. For the new F7 contact insulators are:5

1K-5K Series
The new F7 fibre optic contact has been designed to work in the 1K-5K series.
The main features of these series are as follows:– Security of the LEMO Push-Pull self-latching system– Specially designed for outdoors applications. All these models are waterproof when mated and reach a protection
index of IP 66-IP 68, according to the IEC 60529 standard– Protection against accidental contamination or damage to the fibre end face because the ferrules are recessed within
the connector shell– The alignment key (G, A…F, L and R) ensures excellent repeatability of performance during frequent matings– A choice of configurations of multi fibre or hybrid optical/electrical contacts– The new miniature F7 contact allows hybrid configuration in the 1K series and multi fibre up to 21 channels in the 5K
series.
The 1K-5K series consists of ten models which will accept outer cable diameters ranging from 2.6 mm to 23.5 mm.

Product safety notice
PLEASE READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY AND CONSULT ALL RELEVENT NATIONAL AND
INTERNATIONAL SAFETY REGULATIONS FOR YOUR APPLICATION.
IMPROPER HANDLING, CABLE ASSEMBLY, OR WRONG USE OF CONNECTORS CAN RESULT IN HAZARDOUS
SITUATIONS.
1. SHOCK AND FIRE HAZARD
Incorrect wiring, the use of damaged components, presence of foreign objects (such as metal debris), and / or residue(such as cleaning fluids), can result in short circuits, overheating, and / or risk of electric shock.
Mated components should never be disconnected while live as this may result in an exposed electric arc and local
overheating, resulting in possible damage to components.
2. HANDLING
Connectors and their components should be visually inspected for damage prior to installation and assembly. Suspectcomponents should be rejected or returned to the factory for verification.
Connector assembly and installation should only be carried out by properly trained personnel. Proper tools must be
used during installation and / or assembly in order to obtain safe and reliable performance.
3. USE
Connectors with exposed contacts should never be live (or on the current supply side of a circuit). Under generalconditions voltages above 30 VAC and 42 VDC are considered hazardous and proper measures should be taken toeliminate all risk of transmission of such voltages to any exposed metal part of the connector.
4. TEST AND OPERATING VOLTAGESThe maximum admissible operating voltage depends upon the national or international standards in force for theapplication in question. Air and creepage distances impact the operating voltage; reference values are indicated in the
catalog however these may be influenced by PC board design and / or wiring harnesses.
The test voltage indicated in the catalog is 75% of the mean breakdown voltage; the test is applied at 500 V/s and thetest duration is 1 minute.
5. CE MARKING
CE marking
means that the appliance or equipment bearing it complies with the protection requirements of one orseveral European safety directives.
CE marking
applies to complete products or equipment, but not to electromechanical components, such as
connectors.
6. PRODUCT IMPROVEMENTS
The LEMO Group reserves the right to modify and improve to our products or specifications without providing priornotification.
