The SHV05-1A85-78L3K is a high-voltage reed relay from Standex-Meder Electronics designed for switching applications requiring high voltage isolation up to 1000VAC/DC. The relay uses a hermetically sealed reed switch with SPST-NO (1 Form A) contacts rated for 1A continuous current and 100W maximum switched power. The 5VDC coil has a resistance of 180Ω, drawing only 27.8 mA (139 mW) for low-power operation. The non-latching design ensures the relay returns to its normally-open state when coil power is removed. With a fast 1.1 ms operate time and 0.1 ms release time, the SHV05 series is suitable for high-speed switching applications. The through-hole PC pin termination provides secure PCB mounting for reliable operation in demanding environments.

The SHV05-1A85-78L3K operates through two key mechanisms:

1. Magnetic Actuation: When the 5VDC coil is energized, current flows through the 180Ω coil winding, generating a magnetic field. The magnetic flux penetrates the hermetically sealed glass tube containing the reed switch contacts. The reed blades, made of ferromagnetic material, become magnetized and attract each other, closing the normally-open contacts. The minimum pull-in voltage is 3.75VDC, ensuring reliable operation at nominal 5V supply.

2. Contact Operation: The reed switch contacts are hermetically sealed in a glass envelope filled with inert gas, preventing oxidation and contamination. This enables reliable switching of high voltages up to 1000VAC/DC with low contact resistance. When coil power is removed (voltage drops below 0.5VDC), the magnetic field collapses, and the spring action of the reed blades opens the contacts in 0.1 ms. The fast release time makes this relay suitable for applications requiring quick disconnection.

Pin Name Type Function
1 Coil+ Input Coil positive terminal (5VDC)
2 Coil- Input Coil negative terminal (GND)
3 Contact COM Output Common contact (normally open)
4 Contact NO Output Normally open contact (closes when energized)
  • High-voltage test equipment: Switching of 1000V test signals in automated test systems with hermetically sealed contacts for reliable arc suppression
  • Medical device isolation: Galvanic isolation of patient-connected circuits with 1000V breakdown rating and 139 mW low coil power
  • Industrial safety interlocks: Fast 0.1 ms release time for emergency disconnect circuits in manufacturing equipment
  • Battery management: High-voltage battery pack isolation switching in electric vehicle and energy storage systems
  • Telecom line testing: Switching of telephone line voltages with 1A contact rating and hermetic seal for environmental protection
