Teledyne's space-grade and high-reliability switching solutions are engineered for satellite, launch vehicle, and long-duration mission environments where component failure is not an option. The H-Series latching coaxial switches maintain their switched state without power — critical for power-sensitive spacecraft — and are available in SPDT and transfer configurations with SMA, N, and TNC connectors, covering DC to 26.5 GHz with consistent insertion loss and isolation across mission lifetime. Complementing these are the HR and HRS Series hermetically sealed DPDT electromechanical relays, available in non-latching and magnetic-latching configurations with through-hole and SMT J-lead mounting, including high-shock and high-vibration variants engineered for launch environments. Both product families are qualified to MIL-PRF standards and built for programs where long-term hermetic integrity, radiation tolerance, and mechanical robustness are non-negotiable requirements.

Teledyne's space-grade coaxial switches and electromechanical relays are engineered for satellite, launch vehicle, and long-duration mission environments where hermetic integrity, radiation tolerance, and zero mechanical wear are non-negotiable.

Features

  • HR412/HRS412 DPDT non-latching TO-5 relays: meet NASA/GSFC S-311-P-754 and ESA/SCC 3601 and 3602 per Hi-Rel ATP

  • Space coaxial switches: SPDT (H-32N, H-33S) and transfer (H-37N, H-37S, H-47N) covering L through K band at 50-ohm impedance

  • TR-HIREL-1 specification: developed by Teledyne Relays & Coax Switches, accepted internationally by NASA and ESA programs

  • Screening: 100% pre-cap, PIND, sinusoidal vibration, internal moisture, radiographic inspection, and hermetic leak test

  • Hermetic seal: no leakage in excess of 1 x 10-6 atm-cm3/s per MIL-STD-202 Method 112; 1 x 10-8 atm-cm3/s on HR255

  • Switch blocks: multi-switch integrated assemblies with D-connectors, custom telemetry interfaces, venting, and transient suppression

Benefits

  • 50 years of documented space flight heritage across every mission category reduces program risk when specifying Teledyne Relays & Coax Switches products

  • TR-HIREL-1 eliminates the source control drawing development cycle -- a meaningful schedule and engineering cost reduction for space programs

  • Full data packages and customer source inspection access provide the traceability that space programs require at every level of their quality management system

  • Gold-plated or solder-coated lead finish and factory lead forming eliminate customer rework and reduce handling risk at integration

  • Switch blocks reduce spacecraft harness complexity by consolidating multiple switch paths into a single qualified D-connector assembly

  • In-house environmental test lab, SEM, plating shop, and field technical support provide complete logistic infrastructure behind every delivery

Applications

  • Communications satellites, DBS systems, and VSAT payloads requiring K-band and Ku-band coaxial switch assemblies

  • Deep-space probes and scientific missions requiring screened TO-5 relays with documented NASA and ESA specification compliance

  • Launch vehicles requiring DPDT relay switching for stage separation, pyrotechnic control, and signal routing functions

  • Earth observation and weather satellites requiring high-reliability switching with mission life qualification documentation

  • Manned spacecraft systems requiring the highest available quality and reliability for life-critical switching functions

  • Commercial and military satellite programs requiring switch blocks with custom telemetry interfaces and simplified D-connector integration
