Description
Overview:
The Blue 3.7mm (4BA) Ring Terminal, 100 Pack, is a pre‐insulated electrical termination used to create secure, vibration‐resistant connections on small studs and screws. The 3.7 mm ring suits 4BA hardware (approx. 3.6 mm major diameter), common in control panels and machinery looms. The terminal body is typically tin‐plated copper for low resistance and corrosion protection, with a durable blue PVC insulation sleeve that supports correct crimping and strain relief. Designed for everyday maintenance and small repairs on construction and garden machinery, it helps ensure clean, reliable joints on switches, relays, sensors, and auxiliary circuits. The blue colour generally denotes mid‐range conductor sizes (commonly around 1.5-2.5 mm2), making this a practical choice for workshop and site use. Supplied as a bulk pack of 100 for efficient stocking.
Key Features:
- Pre‐insulated ring design for secure, closed‐loop fastening on 4BA studs and screws (ring Ø 3.7 mm)
- Tin‐plated copper barrel for strong conductivity and resistance to oxidation
- Blue insulation sleeve supports consistent crimps and strain relief during installation
- Suited to typical blue‐range conductors (commonly around 1.5-2.5 mm2) used in control wiring
- Reliable under vibration, helping to prevent loosening in mobile equipment and plant
- Smooth bell‐mouth entry aids wire insertion and reduces strand damage
- Compatible with standard ratchet crimp tools for insulated terminals
- Bulk pack of 100 pieces for efficient workshop stocking and repeat jobs
- Helps maintain tidy, traceable wiring with colour coding for quick identification
- Manufacturer Part Number (MPN): 205 128
Typical Applications:
Commonly used for wiring repairs and new terminations on compactors, generators, mowers, hedge trimmers, small pumps, and control boxes. Suitable for connecting leads to switches, relay coils, terminal blocks, small solenoids, fuse holders, and lighting circuits in plant, landscaping, and horticultural equipment. Ideal for panel‐building, harness assembly, and routine maintenance tasks.
