Heat resistance of contact probes
Product SpecificationsContact Probes
We want to use the contact probe in a thermal environment, but what is the heat resistance status.
Durability varies depending on inspection conditions.For reference, please take a look at the verification test data we conducted in a thermal environment when applying current.
<Verification in a thermal environment>
Verification conditions：
The contact probe was placed in an environment of -40°C and 120°C every hour, and this was repeated 10 times to observe changes in load and resistance value.
Equipment used：
Environmental testing machine
Products used and verification data：
PTP-2PE1L-3GA
PTP-2N1ML-3GA
PTP-256M1-3GA
Result：
There is almost no change in load due to the thermal environment under these conditions.There was an increase in resistance.
＜Current application verification＞
Verification environment：
The contact probe was applied to DC6A for 0.5 seconds and waited for 1 second 200 times, and changes in load and resistance values were observed.
Temperature measurement point：
Measurement by contacting the plunger tip and barrel with a thermocouple.
Products used and verification data：
PTP-2PE1L-3GA
PTP-2N1ML-3GA
PTP-256M1-3GA
Result：
There is almost no change in load due to the application of current.The resistance value increased depending on the individual.
