Harwin Test Report Summary HT01702 Contact Resistance after Aging of Datamate (M80 Series) Connectors HT01702 Test Report for Datamate (M80 Series) Contact Resistance after Aging 1. Introduction. 1.1. Description and Purpose. The Harwin Datamate (M80 Series) connector is manufactured to the requirements of BS9525F0033. The following tests were carried out to test Datamate connector assemblies for contact resistance before and after artificial aging, with periods of 3 years and 15 years. 1.2. Conclusion. The following data has been collated from Harwin test reports 404 and 452. All nine connector samples show that they are performing within the BS9525-F0033 contact resistance requirements. The contacts artificially aged by three years also show good resistance levels and perform well within the 20m requirement. The final test, using samples aged up to fifteen years, produced very low resistance ratings; also remaining within specification. 2. Test Method, Requirements and Results. 2.1. List of Test Samples. a) Samples number 1-6 = M80-8911205 Female assembly with through-board termination mated with M80-8691222 Male assembly with through-board termination. b) Samples number 7 = M80-4100642 Female assembly with through-board termination mated with M80-5010642 Male assembly with through-board termination. c) Samples number 8 = M80-4101442 Female assembly with through-board termination mated with M80-5011442 Male assembly with through-board termination. d) Samples number 9 = M80-4102042 Female assembly with through-board termination mated with M80-5012042 Male assembly with through-board termination. 2.2. Specification Parameters. The Initial Contact Resistance requirement as specified in BS9525-F0033 of age. 2.3. Test Method and Results. Samples were mated and measured for contact resistance. They were then separated, aged for one cycle to IEC 326-2, the equivalent to three years normal storage. They were then remated and contact resistance was measured.
