SDL connector
From Wikipedia, the free encyclopedia
A Shielded Data Link connector is a type of electrical connector in which the signal pins are surrounded by a metal shield. The connector was designed by AMP (now Tyco) and is available with a range of pins (4 to 16), and features a locking mechanism.
It has been used by several different products, most notably on the original IBM Model M keyboard with a detachable cable, and on HP HIL devices (such as keyboards and mice). It is still manufactured but is no longer common on consumer electronic devices.
