Hermetically sealed High-Voltage DC Contactors are the world’s smallest UL508-approved contactors for 1000V high-voltage switching. Since first introducing the ceramic seal in 2006, Sensata | Gigavac sealed contactors have become the preferred choice for any application requiring sealed switching. Utilizing a hermetical seal means these high-voltage contactors exceed the sealing requirements of IP67 and IP69.
Going beyond hermetic sealing, the HX Series can withstand the rigors of virtually any harsh environment whether underwater or in the desert sun. The HX Series of High-Voltage Hermetically Sealed Contactors are particularly suited for inverter systems, battery packs, and combiner boxes in solar or wind power systems.
Applications
- Energy Storage System
- DC fast charging
- Photovoltaic controls

Latching relays provide a unique feature that can be used in any basic relay form, SPST, SPDT, or DPDT. Most relays and contactors are considered “fail-safe.” Fail-safe relays require coil power applied continuously to make sure the relay is switched. Once coil power is removed the moveable contact in a fail-safe relay returns to its default position.
Latching relays require a momentary coil pulse to change the position of the moveable contact. Continuous coil power is not required to keep the relay in a particular switched state. When the application circuit needs to switch a latching relay, it sends a pulse to the coil to change the moveable contact position.

Very high isolation voltages, up to 15kV, are achieved through the use of high vacuum reed switches with either rhodium or tungsten contacts and make these relays suitable for high-reliability applications.
The rhodium contact relays have low contact resistance, while the tungsten contact relays can switch to higher voltages. PCB or panel mount, via nylon studs, versions are available. Connection options for the HV include PCB, solder turret (wire wrap), flying lead, and 0.25” spade terminals.
Features
- 10kV or 15kV Isolation
- Low contact resistance
- PCB or panel mount
- HV connections via flying leads, solder turret (wire wrap), or 1/4” spade terminals
- Excellent AC characteristics
Applications
- Cardiac defibrillators
- Test equipment
- High-voltage power supplies
