5. High temperature test
Test conditions:
1. Contact current/voltage: 10 µA 100 mV 1 kHz
2. Cycle rate 20 cps.
3. Miscontact detection level: 1 mW (= 100 Ohm)
4. Detection method: Observation of all changeover
contacts
Ambient temperature: 80°C ±2°C
Test method:
Test result:
1. All contacts were switched for 100 operations on 2
A 30 V DC resistive load.
2. Samples then were exposed to 80°C temperature
for 5,000 hours, continuous
3. Contact resistance was measured with HewlettPackard testing equipment.
Amber relays showed a stable spread of contact resistance within the initially specified 50 mW after 5,000
hours exposure.

17 contacts out of 20 achieved 10 million no miscontact operations.
NOTES
1. Prevention of vibration and shock
To reduce the likelihood of vibration and
shock, we recommend that you install so
that the contact action is not in the direction of gravity.
