Servo Connectors can be found in several slight variances through history. Variances aside, they almost all are directly compatible with 0.1" (2.54mm) row pins used on circuit boards (including RC receivers). Outside of the hobby servo realm, this connector style is classified as a TJC8 connector. In an attempt to reduce confusion, we call out the gender of the housing and the contacts. For example, an MH-FC connector means that it has a Male Housing and Female Contacts.
