EcoCable Amphenol Helios H4 Connector

Female

In most electrical industries, connectors are described as “Male” and “Female” but this applies to the metal contacts themselves, not the plastic insulator that houses them. For some manufacturers of solar equipment, such as Amphenol, Tyco SolarLok, Multi-contact, and Radox connector systems, the housing of the connector pins appear opposite from standard electrical industries.

For example:

The male pin has housing with a relatively large opening in the end and the pin itself is recessed within. The female pin has housing that has a long narrow tip that fits into the male housing when they are mated. This appearance is just the opposite of what the terms “Male” and “Female” usually bring to mind and is the biggest source of problems in ordering exactly what you, the customer, needs.

When ordering adapters for your PV cables, it is vital to specify the physical type of connector for each end as well as its polarity.
