The 1562-4 is a single end hollow turret terminal from Keystone Electronics, with a tin finish over brass contact material and staking flare termination for through-hole mounting. Overall length is 0.303" (7.70mm), with 0.156" (3.96mm) above board and 0.147" (3.73mm) below the flange. The turret head diameter is 0.093" (2.36mm), the flange diameter is 0.125" (3.18mm), and the mounting hole diameter is 0.067" (1.70mm). Staking side OD is 0.062" (1.57mm).
Board thickness and installation fit
The terminal is designed for a board thickness of 0.125" (3.18mm). The flange diameter matches this board thickness, and the below-flange length of 0.147" (3.73mm) provides clearance for the solder joint or staking flare on the opposite side.
