REFERENCE DATA
1. Life curve
4. Contact reliability
Test conditions:
1. Contact current/voltage: 10 A 100 mV 1 kHz
2. Cycle rate 20 cps.
3. Miscontact detection level: 1 mW (= 100 )
4. Detection method: Observation of all changeover
contacts
Test result:
m = 1.5
95% confidence level = 3.1
17 contacts out of 20 achieved 10 million no miscon-
tact 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 direc-
tion of gravity.
For Cautions for Use, see Relay Technical Information.

2. Coil temperature rise (resistance method)
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.
