These low-profile phone jacks have "snap-in" PC mounting, right-angle plug insertion and available with 2- and 3-conductor circuits and plastic or metal bushings. Ideal for telecommunications, data processing and other high quality audio connecting applications.

Jack circuit selection:
2-conductor * Single open circuit * Shunted tip
3-conductor * Double open circuit * Shunted tip and ring
