Series 516
Zero Insertion Force Socket
Features:
• A choice of 24, 28, or 40 pin count devices can be inserted without bending or
otherwise damaging the legs, since no force is required to either insert or
remove the component from the socket.
• Contacts are normally open and are closed by a unique cam action controlled by
dual lever arms.
• The last 15° of movement of the cam provides a wiping action to the contacts on
the legs of the device to remove any residue, ensuring a gas-tight seal.
• Tapered entry guides help guide the device legs into the mating position with the
contacts.
Specifications:
• Body, handle, and cam are Black UL 94V-0 Glass-filled 4/6 Nylon.
• Pins are Beryllium Copper 170 or 172, 1/2 hard.
• Pin plating:
-10
= 200μ” [5.08μm] min. Matte Tin per ASTM-B545-97 over 50μ” [1.27μm] min.
Nickel per SAE-AMS-QQ-N-290.
-10TL
= 200μ” [5.08μm] min. 90/10 Tin/Lead per MIL-T-10727 over 50μ”
[1.27μm] min. Nickel per SAE-AMS-QQ-N-290.
-11
= 10μ” [0.25μm] min. Gold per MIL-G-45204 over 50μ” [1.27μm] min. Nickel
per SAE-AMS-QQ-N-290. (Consult Factory for Availability).
• Contact current rating=1 Amp.
• Operating temperature: 221°F [105°C] Tin & Tin/Lead plating,
257°F [125°C] Gold plating.
• Minimum Retention Force (when closed)=15 grams/lead, based on a .008 [.20]
thick test lead.
• Accepts most lead widths with lengths from .075 to .250 [1.91 to 6.35].
Mounting Considerations:
•Suggested PCB hole size=.035 ± .002 [.89 ± .05] dia.
