Contact spring
Servometer
Typical applications include:
- Diodes
- Delay lines
- Wave guide components
- Printed circuit boards
Bellows spring contacts are used where the connection cannot or should not be permanent, particularly when the parts are to be inserted, removed and re-inserted. The two types of spring contacts best suited for these applications are gold-plated wire mesh cylinders and gold-plated miniature metal bellows.
Bellows Type Contacts:
Servometer bellows type contact springs are manufactured from electrodeposited nickel, and gold plated to enhance their conductivity. They are flexible and dynamic, and designed to provide a lifetime of reliable interconnection. Furthermore, they can help overcome tolerance buildup and thermal expansion problems in critical assemblies.
The following characteristics make bellows type contacts superior to wire mesh cylinders:
- Minimal of self inductance
- Extremely low DC resistance
- Minimal of insertion loss
- Lifetime spring repeatability
- Only small forces are required (as low as 0.04 oz per 0.001 in. of travel) for compression
- Seamless and non-porous
Operating Conditions:
- Life expectancy from 100 cycles to infinite.
- For greater life cycles, the maximum compression is reduced by 20% for 100,000 cycles and by 30% for infinite life.
- Servometer Contacts can be safely used up to 260°F and maintain their full spring qualities. There is no low temperature limit.
- Our entire stock line is rated for a maximum current of 4 amps.
