For External Applications
Compact, Waterproof

As HEVs and EVs continue to evolve, increasing electronic control and component miniaturization are driving the need for compact, high-reliability connectors in automotive systems.

Designed for Automotive Environments
- Supports applications including ECUs, converters, inverters, and battery systems
- Maintains reliable electrical continuity in −40 to +125℃ environments
- Performs consistently under engine vibration and harsh operating conditions

Stable Electrical Performance
- Tin-plated contacts maintain reliable conductivity under temperature and vibration stress
- Dual spring, three-point contact design ensures stable contact under vibration

Flexible Design Integration
- ZE05 Hybrid Type combines signal and power in a single connector
- Reduces PCB space, component count, and wiring complexity
- Compatible with SMT mounting for improved assembly efficiency

For internal applications, the ZE05 is recommended, while the ZE064W is ideal for external waterproof connection points.

Key Features

High-Temperature Operation (Up to 125℃)

We have conducted rigorous tests required for automotive products, including thermal shock testing (-40 to 125℃ for 3,000 cycles), and have verified that there are no issues. It is designed to withstand temperature conditions such as those found in engine compartments.

Stable Contact Under Vibration

Dual spring and three-point contact design maintain reliable electrical continuity under engine vibration and driving conditions.
Combined vibration testing at 125℃ for 300 hours confirmed stable contact resistance.

CPA Option Prevents Incomplete Mating (ZE05C)

CPA-equipped ZE05C structurally prevents incomplete mating, improving assembly reliability.

Image of CPA on ZE05 Series Connector Diagram showing how CPA detects incomplete mating. Illustrates the operation of CPA and lock lever in three states: un-mated, incompletely mated, and fully mated.

Supports Micro-Coax Wires (AWG 24–26 / 0.13–0.22 mm²)

Enables easier wiring, space savings, and overall cable weight reduction.
Contact options are available as:
ZE05-2426SCF for AWG 24–26 (0.13–0.22 mm²)
ZE05-2022SCF for AWG 20–22 (0.3–0.5 mm²)

Waterproof Design Meets IP67/IP69K Standards (ZE064W Series Only)

By combining the ZE05 Series connectors for internal connections with compact waterproof interface connectors, they can be utilized in a wide range of applications where waterproof performance is required.

Signal + Power in a Single Connector (ZE05 Hybrid)

Supports combined signal (up to 2A) and power (up to 10A) in a single connector.
Design Advantage:
Consolidates signal and power connections—previously mounted separately—into one connector.

Design Benefits:
-Reduces PCB mounting area
-Decreases component count
-Simplifies wiring and assembly processes
-Improves overall design efficiency
