Electrical Characteristics
Contact form SPST Form A Center gap Contact material Ruthenium Switching power (max.) 10 VA Switching Current (max.) 0.5 Amp. Carry Current (max.) 1.0 Amp. Switching voltage (max.) 200 VDC Breakdown voltage (min.) 250 VDC Contact resistance (max.) 200 Milliohms Insulation resistance (min.) 10 Ohms Contact capacitance (max.) 0.5 pF Operate time including bounce (typ.) 1.0 Millisecon ds Release time (typ.) 0.1 Milliseconds Pull in Range 1 – 30 AT Drop out 35 – 90% Note: 1 The specification for VA rating may be exceeded for less sensitive (High AT) switches, and should be d ecreased for very sensitive (Low AT) switches. Specific life testing for a particular load will be run upon req uest. 2. Breakdown voltage is measured in the presence of a radioactive ionizing source with leakage current li mited to 100 microamperes.
