Understanding Gecko Connectors: Compact, Lightweight & Built for Reliability

Harwin’s Gecko range is engineered for applications that demand high performance in the smallest possible footprint. With a 1.25mm pitch, Gecko connectors deliver exceptional space and weight savings — making ideal for robotics, UAVs, industrial automation, and any system where every gram and millimeter matters.

Why Gecko Connectors Excel in Harsh Environments?

1. Compact & Lightweight Design

Gecko connectors offer up to 45% space and 75% weight reduction compared to similar-performance connectors. This enables more efficient layouts in dense electronic assemblies.

2. High-Reliability Performance

Designed for harsh environments, Gecko withstands:

• Shock up to 100g

• Vibration up to 20g

• Operating temperatures from -65°C to +150°C
  This ensures stable performance in motion-heavy and mission-critical applications.

3. Secure Locking Mechanisms

Available in latching and screw-lock versions, Gecko connectors maintain strong retention — reducing the risk of disconnection in high-vibration environments such as drones and robotic arms.

4. Power & Signal Flexibility

Choose from standard Gecko (up to 2A per contact) or Gecko-MT mixed-technology versions that deliver 2A signal + 10A power in one compact connector.
This simplifies cabling and improves system efficiency.

5. Long-Life Durability

Tested for 1,000 mating cycles, Gecko supports repeated use with consistent mechanical and electrical performance.
