Contact rating-Product of the switching voltage and current should never exceed the wattage rating. Contact Hamlin for additional load/life information. Operate/Release Time-per EIA/NARM RS421A, diode suppressed coil. Tel: Tel: Tel: Tel: 4) Pull in Range-Contact Hamlin for tolerances available within this range. 5) Rating Sensitivity-The value at which contact ratings and operating characteristics are determined. Derating may be required below this value. 6) Storage Temperature-Long time exposure at elevated temperature may degrade solderability of the leads. 7) Contact resistance measured at 36 Vdc, 100 ma, switched wet. +1 920 648 3000 • Fax: +1 920 648 3001 • Email: [email protected] +44 (0)1379 649700 • Fax: +44 (0)1379 649702 • Email: [email protected] +49 (0) 6142 923920 • Fax: +49 (0) 6142 923921 • Email: [email protected] +33 (0) 1 6047 3000 • Fax: +33 (0) 1 6015 9136 • Email: [email protected] INFORMATION PROVIDED ON THIS DATA SHEET IS PROVIDED FOR INFORMATION PURPOSES ONLY AND SHOULD NOT BE RELIED UPON AS BEING ACCURATE FOR ANY PARTICULAR PURPOSE.
