What is a JR connector?

Description. This JR connector has a 0.1″ pin spacing and is commonly used on RC servos. Two corners are slightly beveled, which makes it difficult (but not impossible) to incorrectly plug the connector into the corresponding male JR connector. This connector is also compatible with male Futaba J connectors.

Are JR and Futaba connectors the same?

jr futaba and hitec all basically have the same style connector on the servo the wires are arranged the same and the only difference between the futaba and the others is the little tab running down the length of the connector i usually shave off when i get one.

What are servo connectors called?

Futaba “J” connector is the official name.

What size are servo connectors?

For the most part, anything said about a 0.1″ connector applies to servo connectors and vice versa. It is common to append zeroes on the end, like: 0.100″, or use metric (2.54mm) but it all has the same meaning.

Will Hitec servos work with Futaba?

You can mix Futaba servos with an Airtronics receiver, mix Hitec & JR servos with a Futaba receiver, etc. as long as you are careful about polarity. In Futaba, Hitec, and JR Radio servos, the servo and battery connections have the same polarity (+/-) and signal wiring, although the connectors are slightly different.

Are all servo connectors the same?

They use the same plug/connector shells but different pin/wire lineup. Do not plug in old Airtronics servo connectors in “standard” receivers and vice-versa as this will damage the servo. Either extract and reinsert the pins/sockets to match the new/current connector line up or use adapter wires.

How do I calculate JST size?

JST connectors are mostly identified by the length between one contanct to the centre of another contact. There are always between two to higher contacts in a single line. Some families have multiple rows as well. This length is the pitch of the connector type and determines the family that the connector is a part off.
