TELEDYNE RELAYS Everywhereyoulook" Series HR412/ HRS412 DC up to 1 GHz Non-Latching Space Grade DPDT Relay PART NUMBER DESCRIPTION HR412 Non-Latching, DPDT, TO-5 Space Grade Relay (HIREL) HRS412 Non-Latching, DPDT, TO-5 Space Grade Relay (HIREL), Surface Mount J-Leads Teledyne Relays’ HR/HRS412 Series relay is a High Reliability Off-The Shelf relay suitable for demanding space flight applications. When purchased in accordance with Teledyne Relays’ standard Hi-Rel Acceptance Test Procedure (ATP) the relays will meet the basic requirements of both the NASA Goddard Space Flight Center’s S-311-P-754 Document and the European Space Agency’s (ESA) SCC 3601 & 3602 Specifications. The HR/HRS412 Series has become the premier selection for space flight applications requiring low-level switching to dry circuits up to 1 Amp. Teledyne Relays’ 50 year history of supplying relays to the spacecraft manufacturing community has supported 95% of all satellite programs worldwide. Relays may be supplied in accordance with the standard requirements of the Hi-Rel ATP or as specified by customer source control drawings. In addition to enhanced test and inspection at the relay level the individual piece parts are inspected to higher standards. Relay leads may be supplied in either gold (Au) or solder dipped finish. A variety of formed lead configurations performed by the factory are available. All Hi-Rel relays are supplied with full data packages in either hard copy or electronic format. Customer Source Inspection (CSI) may be performed during critical manufacturing and test points. Design Based on QPL-Approved MIL-PRF-39016 Specification Proven Space Flight Heritage Meets the general requirements of NASA/GSFC, S311-P-754 Meets the general requirements of ESA/SCC General Specification 3601 & 3602 1x10-8 Leak Rate Standard Acceptance Test Procedure (ATP) Meets both ESA and NASA Requirements MIL-DTL-45204 Gold Plating ANSI-J-STD-006 Requirements for Electric Grade Solder Alloys and Fluxed and Non-Fluxed Sold Solders for Electronic Soldering Applications 100% Small Particle/ Inspection (Millipore Cleaning) STANDARD HIREL SCREENING

TELEDYNE RELAYS Everywhereyoulook" Series HR412/ HRS412 DC up to 1 GHz Non-Latching Space Grade DPDT Relay GLOSSARY Coil A wire assembly wound around an insulating bobbin or spool. Contact arrangement The combination of contacts that make up the entire relay switching structure. Contact bounce Internally caused intermittent and undesired opening of closed contacts, or closing of open contacts. Contact bounce time The interval between first make of the contact until the uncontrolled opening and closing of the contact ceases. Contact chatter The momentary opening of a closed contact due to external shock...

TELEDYNE DC up to 1 GHz Non-Latching Space Grade DPDT Relay Output The circuit within a relay which controls an external load circuit and is changed from a conducting to a non-conducting state (and vice versa) by the relay operation. Pickup voltage, specified As the current or voltage on a de-energized relay is increased, the voltage at or below which all contacts must achieve their energized positions. Polarized relay A relay, the operation of which is primarily dependent upon the direction (polarity) of the energizing current(s) and the resultant magnetic flux. Production lot A grouping of...
