Aries Electronics

FEATURES:
Aries' Universal Test Socket accepts devices on .300 to .600 [7.62 to 15.24] centers.
All pin count sockets go into PCB with either .300 or .600 [7.62 to 15.24] centers.
Contacts are normally closed to eliminate dependence on plastic to sustain contact.
Socket handle can be configured with closed contacts (on) when in the UP or DOWN position, and can be mounted on either the right or left side.
Sockets can be soldered into PCBs or plugged into any socket. Socket fits into Aries' or any competitive test socket receptacle.

SPECIFICATIONS:
Socket body is black UL 94V-0 Glass-filled Polyphenylene Sulfide (PPS).
Handle is Stainless Steel.
Handle knob is Brass Alloy 360, 1/2 hard.
Contacts are Beryllium Copper Alloy 172 per QQ-C-533 or Spinodal Alloy.
Beryllium Copper contact plating is either 100 u [2.54 um] min. Tin per MIL-T-10727 or 10 u [.25 um] min. Gold per MIL-G-45204 over 50 u [1.27 um] min. Nickel per QQ-N-290.
Spinodal contact plating is 50 u [1.27 um] Nickel Boron.
Contact current rating=1 Amp.
Insulation resistance= 1000M Ohms min.
Dielectric withstanding voltage=1000 VAC.
Life cycle: 25,000 to 50,000 cycles.
Operating temperature:
    221°F [105°C] Tin Plating,
    302°F [150°C] Gold plating,
    392°F [200°C] Nickel Boron plating.
Retention Force (when closed) = 55 grams/pin based on a .020 [.51] diameter test lead.
Accepts leads .015-.045 [.38-1.14] wide, .110-.280 [2.79-7.11] long.
