Series of bus switching relays designed for use in the test and simulation of MIL-STD-1553 data buses. They are particularly useful in reconfiguring bus systems. (read more)
A high current double throw relay in a PC mount. We took our G41C relay and put it in a reed relay style PC mount package. The result is a hefty double throw relay unlike any reed relay in the industry. It can even hot switch limited high voltage current (contact GIGAVAC for ratings). The G81C is available with PC or flying lead terminal (see G81 data sheets for details. (read more)
TLC Electronics, Inc. is proud to announce the release of Arcolectric's 1550 and 1350 series of double pole, high in-rush current rocker switches with protective guard option. (read more)
A low cost slim design RF & DC rated single pole high voltage vacuum relay for high-density packaging. Available in single pole single throw normally closed (SPST-NC), single pole single throw normally open (SPST-NO), and single pole double throw (SPDT) configurations. (read more)
The highest voltage rated relay we have in a slim design, the GIGAVAC G47 vacuum relay is ideal for RF & DC applications where high-density packaging is required. Available in single pole single throw normally closed (SPST-NC) and single pole single throw normally open (SPST-NO) configurations. (read more)
Filled with a SF6 gas mixture, it is safe for years of x-ray free capacitive "make" service or where very low and stable leakage current is needed. Like it's G71 big brother, It is impervious to most external contaminants, it's not position sensitive, it can be mounted in any direction, it will operate from –55º C to + 85º C and is available in forms A, B & C.

The smallest sealed 70 kV relay in the industry! Filled with a SF6 gas mixture, it is x-ray safe for years of failure-free capacitive "make" service or where very low and stable leakage current is needed. Impervious to most external contaminants, not position sensitive, and operates from –50º C to + 85º C. Available is forms A, B & C with custom wire lengths. (read more)
The GIGAVAC G81A normally open and G81B normally closed HV relays are like our reed relay but on steroids! We took our G41 relay and put it in a reed relay PC and panel mount package. The result is higher stand off voltage than our G41 relay, up to 4 times the current carry of our best reed relay, and hot switching capability not available in such a small package. (read more)
A long life high voltage vacuum reed relay provides years of failure free service in the harshest environments. The GR5LT is available in either normally open (SPST NO) or normally closed (SPST NC) configurations with PC mount or flying leads. Coil choices are 5, 12 or 24 Vdc with specials available upon request. Most models are in stock at GIGAVAC for same day shipment. (read more)
