Electrical Characteristics
Contact form SPST Form A off Center gap Contact material Rhodium Switching power (max.) 0.3 VA Switching voltage (max.) 28 VDC Breakdown voltage (min.) 200 VDC Contact resistance (max.) 200 Miniohms Insulation resistance (min.) 10 Ohms Contact capacitance (max.) 0.2 pF Operate time including bounce (typ.) 1.0 ms Release time (typ.) 0.1 ms Pull in Range 10 – 50 AT Drop out 40 – 90% 1. The specification for VA rating may be exceeded for less sensitive (High AT) switches, and should be decreased for very sensitive (Low AT) switches. Spe cific life testing for a particular load will be ru n upon request. Note: 2. Breakdown voltage is measured in the presence of a radioactive ionizing source with leakage current limited to 100 microamperes.
