Poka-Yoke Connector Design Assurance

Introduction

A smart connector strategy makes wiring safer, cleaner, and far more reliable for automotive electronics.

Introduction

Why Poka-Yoke Matters in Vehicle Electronics

Unique Mechanical Keys for Every Connector

The Moduline M1 and Moduline L4 both use automotive-grade TE Connectivity Superseal 1.0mm connectors. However, they do not use a single generic connector housing. Instead, each controller type uses different keyed connector housings, as documented in the hardware manual.
These mechanical keys block incorrect mating by:

• Allowing plug-in only in the correct orientation
• Preventing accidental cross-connections between connectors
• Separating power, CAN, sensor inputs, and output wiring
  As a result, wiring becomes more predictable and far more robust.

Error-Proof Installation and Servicing

Compatible With Standard Automotive Processes

Although the connectors are uniquely keyed, GOcontroll still uses standard TE Superseal components, which means:

• Common tooling works without changes
• Standard crimp contacts remain compatible
• Automotive wiring harnesses follow well-known practices
  Therefore, teams avoid special tools or custom training. They gain a safer interface without changing their workflow.
