HARWIN Z125-900, Crimping Tool for Gecko Male and Female Crimp Contacts, 26 → 32 AWG

The Harwin Z125-900 is a precision, ratcheting hand-crimping tool, purpose-built for the Gecko series 1.25 mm pitch high-reliability connectors. Engineered for male and female signal contacts, it supports wire gauges from 26 AWG down to 32 AWG (0.14–0.08 mm²) and includes an 8-indent crimp form mechanism. This tool ensures consistent and repeatable crimps, perfect for mission-critical interconnect assemblies in electronics manufacturing, aerospace, defence, and industrial applications.

How It Benefits Users

• Ratcheting mechanism ensures complete crimp cycle before release for consistent termination quality.
• 8-indent crimp form delivers reliable mechanical and electrical performance.
• Lightweight (≈336 g) and ergonomic for repetitive use.
• Compatible with Gecko positioner (Z125-901) for precise alignment of crimp contacts.
• Designed for high-reliability connector assemblies (1.25 mm pitch) in demanding environments.

Designed for Precision Termination in High-Reliability Systems

The Z125-900 is tailored for exacting interconnect assemblies that require signal integrity, vibration resistance, and long service cycles. The ratchet mechanism prevents premature release, ensuring the crimping cycle completes fully, helping to avoid under- or over-crimp conditions.

Typical Uses of the HARWIN Crimping Tool

• Termination of multi-conductor cables (26–32 AWG) in aerospace and defence wiring looms.
• Manufacturing board-to-wire or wire-to-wire connector assemblies for rugged industrial systems.
• Production and servicing environments where reliable, repeatable crimps are essential.
• Cable assembly for instrumentation, test equipment and high-reliability connectors.
