Standex Electronics Unveils High-Performance High-Voltage Reed Relays
Standex Electronics, a leading supplier of custom-engineered electromagnetic components, has announced the launch of its new line of high-voltage reed relays. These relays are designed for applications demanding high-voltage insulation, precise switching, and reliability, such as automated test equipment (ATE), medical devices, electric vehicles (EVs), and alternative energy systems.
Key Applications
The high-voltage reed relays from Standex Electronics are particularly well-suited for the following key applications:
- Automated Test Equipment (ATE): The relays provide reliable high-voltage isolation and low power consumption for signal switching and measurement in test systems.
- Medical Devices: They support precise and safe switching of medical instrumentation signals, benefiting from their miniature size and high reliability.
- Electric Vehicles and Hybrid Vehicles: These relays handle switching in EV powertrain components, battery management systems, and charging infrastructure, offering robustness and high-voltage capability.
- Alternative Energy Systems: They are used in photovoltaic (solar) energy systems, wind power generation, and battery charging control, where high insulation and durability are critical for DC power systems.
Specifications
Typical specifications of these reed relays include:
- Contact form: Single-pole single-throw normally open (SPST-NO) or forms like 3 Form A (3PST-NO).
- Coil voltage: Commonly 24 VDC for excitation.
- Switching voltage: Up to 200 VAC or high DC voltages (specific values depend on the model).
- Maximum switched current: Generally around 1 A or rated power up to 50 W in some models.
- Miniaturized PCB mounting: Small packaging suitable for compact system designs.
Examples of these relays include the BE24-3A74-M relay, which features a coil voltage of 24 VDC, 3 Form A contacts, switching voltage up to 200 VAC, and max switched current of 1 A. Another model, HM05-1A69-02, is a miniaturized high-voltage SPST-NO relay rated for 50 W power, designed to provide reliable high-voltage switching and insulation.
Key Features
The high-voltage reed relays from Standex Electronics are engineered with hermetically sealed rhodium or tungsten contacts for long-lasting operation and breakdown/stand-off voltage levels up to 15 kVDC. They also offer contact resistance in the range of tens of milliohms, reliable and swift switching times below 1 millisecond, and are designed for environments requiring low leakage currents and high insulation resistance.
With these new high-voltage reed relays, Standex Electronics continues to push the boundaries of electromagnetic component design, providing solutions that meet the evolving needs of industries focused on high-voltage applications.
