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.

SERIES SN37A - Right-angle PC mount phone jack with molded plastic housing. Only .375 inches high, this jack features a plain (non-threaded) bushing and accepts commercial standard phone plugs with .25 inch diameter finger.

Jack circuit selection:

2-conductor * Single open circuit * Shunted tip

3-conductor * Double open circuit * Shunted tip and ring

Jack housing snaps into PC boards (.062 inches thick) and features molded tension fingers to provide stable mount. Location pin polarizes mounting for correct insertion every time. Clearance between housing facilitates board cleaning without distrubing internal springs. SN37 without tension fingers available on special order.

Molded housing protects internal parts and allows high density packaging. Supplied with "Snap-On" cover.
