4. Contact reliability
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
5. High temperature test
Test conditions:
Ambient temperature: 80°C
±2°C
Test method:
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 Hewlett-
Packard testing equipment.

17 contacts out of 20 achieved 10 million no miscon-

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 direc-
tion of gravity.
