## Long description

Tin-plated ring ferrules Erko KOE\_4-2,5/100 are crimp terminals designed for stranded conductors with cross-sections from 1.5 to 2.5 mm². Supplied in a pack of 100 pieces, each ferrule provides a consolidated conductor end suitable for insertion into screw terminals, terminal blocks and distribution panels. The tin plating improves corrosion resistance and ensures stable electrical contact over time when paired with an appropriate crimping tool.
Advantages
Ring ferrules provide a consistent mechanical connection and reduce the risk of stray strands and loose conductors. The tin-plated finish offers improved resistance to oxidation compared with bare copper, helping to maintain low contact resistance. Delivered in a set quantity, these ferrules simplify material handling for installation tasks and help achieve repeatable crimp quality when used with matching crimp dies.
Suitable for
Stranded copper conductors with cross-section 1.5–2.5 mm²
Screw terminals and terminal blocks in electrical panels
Control cabinets and industrial assemblies
Residential electrical installations and junctions
Key specifications
Conductor cross-section: 1.5–2.5 mm²
Contact type: ring ferrule for screw connection
Material: copper core with tin plating
Pack quantity: 100 pieces
Designed for stranded wire termination
How to use
Strip the conductor to the recommended length for the ferrule barrel, insert the stranded wire fully into the ferrule so that no strands remain outside, and crimp using a suitable crimping tool and die for the specified cross-section. After crimping, fit the ring end onto the terminal stud or screw and tighten to the terminal manufacturer's torque specification to ensure secure mechanical and electrical contact.
Usage recommendations
Use a dedicated crimping tool with the correct die for 1.5–2.5 mm² ferrules to achieve reliable crimps. Avoid reusing deformed ferrules and select tin-plated ferrules for environments where improved corrosion resistance is required. Verify terminal screw torque after assembly for consistent performance.
