The SGX Series complements Sensata Technologies’ wide portfolio of contactors with solutions ideal for low-power applications that require reliable switching and efficient design at a strong performance-to-cost ratio, such as residential energy storage systems, DC fast-charging stations, and industrial applications such as electric forklifts and Automated Guided Vehicles (AGV). The new SGX series utilizes ceramic-to-metal weld technology with several advantages:
- Hermetically sealed for optimal breaking capabilities
- Usage up to 175°C with effective handling of over-current conditions
- Gas backfilled (primarily hydrogen), resulting in low and stable contact resistance
- Tailored to residential Energy Storage Systems (ESS), DC fast charge, industrial AGV / forklift applications
Complies with IEC 60664-1 and RoHS standards
- The SGX series offers optimal breaking capability for applications up to 1000Vdc and 50A/150A/250A continuous current carry, with an efficient design, effective and reliable switching, longevity, and a square form-factor.

The GXVB611 is a bidirectional contactor with auxiliary contact functionality to provide reliable DC switching. With rated voltage up to 1000VDC and nominal current ratings up to 600A, this dual-coil design is an ideal fit for applications such as megawatt EV charging and other industrial uses.
Features
- Gas-filled design offers lower resistance than non-hermetic switches resulting in higher system efficiency and less heat generation. Meet IP67 level.
- Suppression gas allows high fault interrupt capability and prohibits oxidation—Strong capability of cooling arc, rapidly breaking current.
- High Efficiency Dual DC Coils – Very low 12 or 24 VDC continuous coil power with no EMI emissions or cross-talk on your system control power. Ideal for battery-powered systems or where low power is needed.
- Built-in coil suppression for all DC coils – Saves you engineering time and parts cost to add external coil suppression.
- Certification: UL 60947-4-1, CE(pending)
Applications
- DC fast charging
- Energy storage systems
- Battery electric special mobility

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

Single-Pole Single-Throw relays provide the most straightforward approach to isolation. A single stationary contact and a moveable contact furnish a simple on-off configuration. Forms include normally open (NO) and normally closed (NC). Normally open relays provide voltage isolation until coil power is applied. With coil power applied there is continuity through the relay contacts. Normally closed relays provide continuity through closed contacts until coil power is applied where the relay contacts open providing isolation.
Sensata | Gigavac offers several design styles including High-Voltage and RF reed relays along with traditional ceramic vacuum and gas-filled High-Voltage Relays. Each of these relay design types offers unique advantages depending on the application.
