The probe is a tool to verify the protection of person and equipment by enclosure. Standard IEC61032 specifies the details and dimensions of test probes intended to verify the protection provided by enclosures against access to hazardous parts inside of the enclosure and ingress of solid foreign objects.
According to their designation, the test probes can be classified as:
1)IP code probes
2)Other probes
According to the kind of protection they are intended to check:
1)Access probes
2)Object probes
According to the specific hazard they are intended to check:
1)Probes mainly intended to be used to verify the protection of persons against access to hazardous live parts or hazardous mechanical parts.
2)Probes specifically intended to be used to verify the protection of persons against access to hazardous mechanical parts.
3)Probes mainly intended to be used to verify the protection of persons against access to internal parts involving thermal hazard, for instance internal hot or glowing parts.
4)Probes intended to be used to verify the protection of equipment against ingress of solid foreign objects.
Access probe is a test probe simulating in a conventional manner a part a person or a tool, or the like , held by a person to verify adequate clearance from hazardous parts.
Object probe is a test probe simulating a solid foreign object to verify the possibility of ingress into an enclosure.
IP code probe is a test probe to verify the degrees of protection specified in IEC60529.
Other probe is a test probe, different from IP code probes.

In practice, IP test probes should be selected on priority, the other probes should be limited to use in the cases where the use of an IP code probe is impractical for some reason. Pego not only can provide the complete solution of probes for verification, but also can provide the customized service for some special probes mentioned in some product standards.
