Connecting ferrule sleeve Ergom 2ZA35 aluminum (E12KA-01070100300)

Connecting ferrule sleeve Ergom 2ZA35 aluminum is a compact, conductive aluminum sleeve designed to form secure mechanical and electrical joints on wires and cables. Intended for crimping or joining conductors, this ferrule sleeve creates a durable junction point that helps ensure reliable continuity and mechanical stability in electrical installations, harness assemblies, and repair tasks where space is limited and a conductive connection is required.

Advantages

The aluminum construction provides good electrical conductivity while remaining lightweight. Its sleeve shape allows consistent crimping to create mechanically stable connections that resist vibration and movement. The product is suitable for use with different conductor types where a compact and conductive junction is needed, and the simple geometry supports repeated, predictable installation with standard crimping tools.

Suitable for

• Crimped splices and butt joints on aluminum or compatible conductors
• Electrical installation work in cabinets, junction boxes, and control panels
• Harness assembly and maintenance in industrial and automotive contexts
• Field repairs and on-site conductor joining where a compact conductive joint is required

When it may not be suitable

This aluminum ferrule sleeve is not intended for insulation or environmental sealing by itself and should not be used where a fully sealed or heat-shrink insulated connection is required unless an additional sealing layer is applied. It may not be appropriate for conductors or applications that explicitly require copper-only connectors, stainless steel fittings, or specialized plated contacts for dissimilar metal corrosion concerns without proper treatment.

Key specifications

• Material: aluminum
• Form factor: tubular sleeve for mechanical crimping
• Intended connection type: crimped mechanical and electrical joint
• Typical applications: wiring splices, harness assembly, repair work
• Size class: designed for compact conductor junctions (2ZA35 series)

How to use

Strip the conductor insulation to expose the appropriate length of conductor, insert the conductors into the aluminum sleeve so the joint is centered in the sleeve, and apply a suitable crimping tool matched to the sleeve size for a firm mechanical deformation. After crimping, inspect the joint for secure compression and verify electrical continuity. Where additional protection is needed, apply insulation tape, heat-shrink tubing, or an environmental seal over the sleeve following the crimping operation.

What to consider before purchase

• Confirm compatibility with conductor material and cross-section to ensure reliable crimping
• Ensure you have the correct crimping tool and die set for aluminum sleeves of this size
• Decide whether additional insulation or sealing will be required after crimping
• Assess whether aluminum is acceptable for your application regarding conductivity and galvanic compatibility

Usage recommendations

Use a calibrated crimping tool appropriate for aluminum sleeves and perform a pull and continuity test after crimping. Where galvanic corrosion may occur, consider using compatible materials or protective coatings and add mechanical strain relief to prevent stress on the crimped joint.
