(jis c5003) the equation, 60 =0.510 -6 /operation, indicates that the estimated malfunction rate is less than operations with a reliability level of 60%. m2 tap 1.6 dia. holes 5.5 0.1 3.8 0.1 6 4.5 3.5 1.4 5.6 4.2 1.6 fp op 6.5 5.5 0.15 2 +0.12 dia. holes 0 4 1 3.8 0.15 1.5 0 dia. -0.12 8 4 2.54 2.54 0.8 0.9 0.3 a 8 2.54 3-1 dia. holes 2.54 4.2 3 1 2 3 1 2 >& nc >' >& no >' fp op1 non-shorting model op2 ttp >& nc >' >& no >' fp op1 shorting model switching timing op2 ttp D2A-1110, D2A-1120 D2A-2110, D2A-2120 models non- shorting model shorting model operating characteristics model D2A -1110 D2A -1120 D2A -2110 D2A -2120 operating force of max releasing force rf min. 0.98 n {100 gf} 0.15 n {15 gf} 0.49 n {50 gf} 0.05 n {5 gf} 0.98 n {100 gf} 0.15 n {15 gf} 0.49 n {50 gf} 0.05 n {5 gf} free position fp max. operating position op1 op2 total travel position ttp 9.5 mm 8.1 0.3 mm 7.4 0.3 mm 6.5 0.2 mm 9.5 mm 8.0 0.3 mm 7.5 0.3 mm 6.5 0.2 mm cautions correct use switch mounti surface 1 2,000,000 30 24 12 5 0 1 10 100 1,000 current (ma) 0.1 1 ma operating range 0.16 ma 100 ma voltage (v)
