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 Test result: m = 1.5 m = 21.2 x 106 95% confidence level = 3.1 x 106 17 contacts out of 20 achieved 10 million no miscon- tact operations. 0.1 0.5 1.0 5.0 10.0 50 100 0.1 0.2 0.15 0.3 0.4 0.5 1.0 1.5 2.0 3.0 4.0 5.0 10.0 20.0 25.0 30.0 40.0 50.0 60.0 70.0 80.0 90.0 95.0 99.0 99.9 15.0 No. of operations, ×106 F(t)(%) 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. Test result: Amber relays showed a stable spread of contact resis- tance within the initially specified 50 mW after 5,000 hours exposure. 100 200 300 400 500 1,000 5,000 3,000 0 10 20 30 40 50 60 70 Exposure, hrs.
