Overview
The Brad Harrison 7A3006-31 is a Micro-Change D series 3-pole attachable connector designed for field installation in industrial applications. Rated at 4A continuous current and 300V maximum, this connector combines rugged construction with the convenience of push-to-lock quick-disconnect connections. The male straight configuration with IP67 ingress protection makes it ideal for wet environments, washdown areas, and demanding factory settings where reliable sensor and device connectivity is critical.
Key Features
- 3-pole configuration for multi-channel signal and power transmission
- Push-to-lock quick-disconnect design for rapid field installation and replacement
- 4A rated current capacity at 300V operating voltage
- IP67 ingress protection rating—sealed against dust, moisture, and washdown spray
- Field-attachable design allows wire termination on-site without special tooling
- Male straight connector body for consistent mating with standard Brad Harrison receptacles
