1/4" RIGHT-ANGLE PHONE JACKS
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" high, this jack features a plain
(non-threaded) bushing and accepts commercial standard phone
plugs with .25" 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" 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 disturbing
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.
