3 / 8 page  NR 114 DIFFERENCES BETWEEN NR RELAYS AND REED RELAYS NR relays Reed relays Structure Contact arrangement 1 Form C 1 Form A or 1 Form B Contact capacity 20 W (high contact pressure) 5 to 15 W Operating function Single side stable Latching Single side stable "Getter" hole Yes No "Getter" holes are formed on both pole shoes to obtain uniform contact resis- tance throughout life. Film-forming phe- nomena on contacts is thus fully prevented. REFERENCE DATA 1.-(1) Contact reliability Test sample: NR-SD-24V 54 pcs. Circuits: (A) Following figure with diode (B) Following figure without diode Item to be checked: Detect with the circuit stopped Circuits: (A) Diode provided: The circuit does not stop through- out 100 million times. (B) Diode not provided: λ60 = 2.5 × 10-8 times 1.-(2) Contact reliability TEST CONDITION Sample: NR-SD-24V, 10 pcs. Contact voltage: 100 mV Contact current: 10 µA Cycle rate: 50 cps. Detection level: 100 Ω Testing operation: 3 ×107 m = 1.9 σ = 2.5×107 µ = 4.7×107 95% reliability limit: 1.15 ×107 (Mean time between failure) 2.
