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 Ω) 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 HewlettPackard testing equipment.
Test result:
Amber relays showed a stable spread of contact resistance within the initially specif ed 50 mΩ after 5,000 hours exposure.
