Electrical Characteristics
Contact Arrangement Form A (SPST), Center Gap Contact Material Rhodium Power Rating 1 70VA maximum Switching Voltage (Max.) 300 VDC, 300 VAC Breakdown Voltage (Min. @20AT) 2 750 Volts DC Contact Resistance 3 100 Milliohms Insulation Resistance (Min.) 10 12 ohms Contact Capacitance (pf Max.) 0.3 pf 1. The specification for VA rating may sometimes be exceeded for less sensitive (higher AT) switches, and should be decreased for very sensitive (lower AT) switches. Standex-Meder Electronics will run life tests specific to a customer’s load upon request. 2. Breakdown voltage is measured in the presence of a radioactive ionising source. Switch leakage current is limited to 100 microamperes 3. Contact resistance measurements are made at 10ma from a 1-volt source, with 50% overdrive, using a 4-wire (Kelvin) measuring system. Contact probes are located on 43 mm centres. Minimum Switching Life with Standard Test Loads, using 20AT switch Voltage 24 VDC 100 VDC 125 VAC 240 VDC 240 VAC Current 10 mA 100 mA 80 mA 40 mA 40 VA lamp load, 5 sec, 10% duty cycle Life 5 x 10 6 1 x 10 6 1 x 10 6 2 x 10 5 5 x 10 5 Note: End of life is defined as contact resistance exceeding one ohm and/or failure to operate.
