The construction of PT058 :
The plunger is made of high carbon steel or full-hard beryllium copper plated with gold to eliminate surface oxides and to lower electrical resistance.
Various probe tip styles are adopted to suit any test requirement according to different applications.
Spring is constructed of stainless steel wire, plated with gold which prevents corrosion.
The barrel is made of phosphor bronze, plated with gold. The interior of the barrel makes good electrical contact with the plunger and spring whereas the exterior of the barrel makes good electrical contact with the receptacle.
The receptacle is made of phosphor bronze plated with gold. Phosphor bronze has the features of excellent electrical conductivity, corrosion resistance, wear resistance and fatigue resistance.

HOW TO eliminate contact problems caused by dirty probes
Preventive Maintenance:
Environment – reduce airborne contamination such as dust, clothing fibers or particles from an adjacent wave-solder machine
PCB –keep printed circuit boards as clean as possible
Dust Covers – put dust covers over idle fixtures
Air Filters –fixing an air filter in the release port
Probe Cleaning:
Gently brushing the probe tips with a small brush with nylon or natural fiber bristles
