50pin Crimp D-sub Male Smooth Hole

Manufacturer :ANTENK ELECTRONICS.,CO LTD.

D-Sub and DB are prefixes used to describe a type of multi-pin connectors that happen to be commonly used in audio equipment. The original manufacturer, ITT Cannon, adopted the [D" designation as the lead character in their part numbers signifying the connector type. The shell size, or capacity, is next in the part number: A=15 pin, B=25 pin, C=37 pin, D=50 pin and E=9 pin (not originally produced). This type connector can also be specified with many different styles and quantities (up to its capacity) of pin: high power, coax and combinations. The most common connector, early on, was the 25-pin size, which was used on RS232 ports (a common computer port). Hence DB25M means [D" type, [B" shell, 25 pins, Male pin. Note that a 15-pin female would be DA15F. D-Sub is short for the current industrial tag, D-Subminiature, used by almost all of the manufacturers.
