Crimp Ferrule Terminal

-- Steady & Reliable Manufacturer --

Crimp Ferrule Terminal Overview

A crimp ferrule terminal — also called a wire ferrule, end sleeve, or bootlace terminal — is a small copper tube crimped onto the stripped end of a stranded wire to consolidate all strands into a single solid pin. When inserted into a screw-clamp or spring-clamp terminal block, the ferrule presents a clean, corrosion-resistant contact surface and prevents individual strands from fanning out, short-circuiting adjacent terminals, or loosening over time.

Fenglan manufactures crimp ferrules in electrolytic copper, tin-plated, with colour-coded PA nylon insulation collars in sizes from 0.25 mm² to 95 mm² (AWG 23 – 3/0). Twin-wire ferrules for two conductors in one terminal position are also available.

Application

  • Control panel and PLC wiring — terminating sensor, I/O, and power supply stranded wires into screw-clamp and spring-clamp terminal blocks for vibration-free long-term contact
  • DIN rail terminal assemblies — the standard pre-termination step before inserting wire into any push-in or cage-clamp terminal block
  • Switchgear and protection relays — secondary wiring to relay coils and CT/VT terminals where stray strands could cause misoperation
  • Frequency inverter and servo drive cabinets — control and signal wiring where loose strands near high-frequency bus bars could cause EMC issues
  • Building automation and BMS panels — neat, professional wiring of HVAC sensors, actuators, and fieldbus devices
  • Renewable energy inverters and battery systems — high-cycle-life ferrules on battery management wiring subject to thermal expansion
  • Marine and rolling-stock panels — vibration-resistant termination satisfying EN 50155 railway and Lloyd's marine wiring standards

Advantage

  • Eliminates stray strand risk — the tin-plated copper sleeve consolidates all strands into a single solid pin; no individual strand can escape to bridge an adjacent terminal and cause a short circuit
  • Consistent, repeatable crimp quality — quadrant-die ferrule crimpers apply uniform pressure on all four sides simultaneously, producing a square-section pin with precisely controlled dimensions every time
  • Corrosion-resistant tin plating — the tin layer over the copper sleeve prevents oxidation at the wire-to-terminal interface, maintaining low contact resistance throughout the service life without periodic re-tightening
  • IEC 60228 colour coding — internationally standardised collar colours let any engineer worldwide identify wire cross-section instantly, reducing wiring errors and simplifying troubleshooting
  • Twin ferrule for two-wire positions — twin ferrules allow two conductors to be terminated in a single terminal block position, halving terminal count in common-bus wiring without increasing space
  • Compatible with all major terminal brands — pin dimensions conform to DIN 46228-1/4, ensuring compatibility with Phoenix Contact, Weidmüller, Wago, and equivalent terminal blocks without modification

FOB Changzhou and CIF terms are both available. All goods are packed in export-standard cartons with foam padding or wooden crates for heavy items. A commercial invoice, packing list, and COA are provided with every shipment. For large OEM orders, customized packaging and private-label options are available upon request.

  • Q: Is a ferrule necessary if my terminal block already has a clamping plate?
  • A: Most terminal block manufacturers strongly recommend ferrules even with their own clamping systems. Without a ferrule, repeated tightening of the screw can sever individual strands, reducing the conductor cross-section and raising contact resistance. Ferrules also make re-termination far easier because the pin slides cleanly out of the terminal slot without snagging individual strands.
  • Q: What type of crimping tool produces the best ferrule crimp?
  • A: A quadrant-die (four-indent) ratchet crimper is the industry standard for ferrules. It applies four symmetrical indentations that produce a square cross-section pin, which provides maximum contact area in a rectangular terminal slot. Pliers-type or two-jaw crimpers produce round crimps that contact only two points in a rectangular slot — adequate for occasional use but not recommended for production wiring.
  • Q: Can I use a twin ferrule with spring-clamp (push-in) terminal blocks?
  • A: Twin ferrules are compatible with spring-clamp terminal blocks rated for the combined wire cross-section. For example, a 2 × 1.5 mm² twin ferrule (total 3 mm²) requires a terminal block rated for at least 4 mm² wire. Always check the terminal manufacturer's datasheet for the maximum pin dimensions accepted by the spring cage before specifying twin ferrules.
  • Q: How do I choose the correct ferrule pin length?
  • A: The pin length must match the insertion depth of the terminal block. Most DIN rail terminal blocks accept 8 mm or 10 mm pins. Check the terminal block datasheet for the rated wire insertion depth and select a ferrule with a pin length equal to or slightly shorter — a pin that bottoms out before the collar contacts the terminal face leaves a gap that can cause a high-resistance joint.
