Why would our customers want us to test their reed relay and/or sensor for dynamic contact resistance (DCR)?

Very simply it will improve the quality and reliability of the product by weeding out these various problem types:

• Overstressed reed switch usually from assembly
• Small crack on the reed seal
• Broken reed switch
• Plating or sputtering pealing off
• Air contamination in the glass capsule
• Particles on the contacts
