Any grid size available on either 1.27mm [.050"] or 1.50mm [.059"] pitch.
Lidless design - ball locks into two-fingered contact.
Ultra-low profile socket adds only .050 [1.27] to overall package height (.100 [2.54] with SnapAdaptTM pins).
Corner guides aid in package insertion (not used with SnapAdaptTM pins).
Consult Data Sheet Nos. 23003 and 23004 for Aries BallNestTM Socket.
