LOW PROFILE SPRING CONTACTS Standard and custom solutions to meet your needs KEY DATA OF A SPRING PIN Spring loaded contacts are used to make reliable connections in case of misalignment and high tolerance issues between two boards. They are mainly defined by three characteristics: Working Stroke, Height, and Operating force:    The working stroke is equal to the tolerance present between the two boards; a standard working range is 1.4 mm (.055”). The height of a spring pin is a little bit bigger than the maximum distance between the two boards, in order to have a buffer area to guarantee an operational contact in all cases. The operating force must be larger than 0.5N in order to guarantee the reliability of the contact between pad and piston. Working Stroke Height SPRING LOADED CONTACT: STANDARD DESIGN A spring loaded contact is composed of a barrel, a spring, and a piston. These are engineered to meet specific application requirements (height, stroke and force, as well as environmental constraints). PRECI-DIP Spring Loaded Contacts With an Integrated CLIP Spring Loaded Contacts With Standard design Rigid Sliding Piston Fixed body Rigid Sliding Piston Contact point between two rigid Flexible Contact point Multi-Finger elastic clip Fixed body Main advantage of this design is it compactness; the minimal length is 2.5 mm for a 0.6 mm stroke and a mid-stroke force of 0.7N. See 90173-AS for reference. Main disadvantage is that this contact will disconnect under shock and vibration SLC conditions. This solution is only suitable in static-mode, and low current applications. An integrated Multi-Finger elastic clip establishes a reliable and efficient multi point connection between body and piston. Flexible contact is compliant to shock and vibration up to 2000Hz or more, and accommodates currents up to 20A. This high tech solution requires more space; see typical dimension for a SLC with clip on our Series0900-CLIP.

Standard Surface Mount Reverse Surface Mount Design • Easy to implement with tape and real option; see • The entire height of the Spring Loaded Contact must remain over the board. • Easy to implement with reverse tape and real option. • A portion of the height of the Spring Loaded Contact remains within the board. Surface Mount Design • The board height of this SLC can be adapted easily by moving the shoulder over Spring Loaded Contact body. • Board to board distance can be as little as 2.5mm • Pin and Paste technology requires a portion of the SLC body within the board. • The stop shoulder can...
