Assemtech SPST-NO PCB Reed Switch 500 mA 180 V RI-27AAA

Assemtech RI-27AAA is a high-quality SPST-NO PCB Reed Switch designed for industrial and electrical applications requiring reliable switching under low current and voltage conditions. Rated for a maximum switching current of 500 mA and voltage of 180 V, this reed switch features ruthenium plated contacts on gold ensuring extremely low contact resistance of 115 mΩ and long electrical life.

The reed switch is hermetically sealed in a gas-filled glass envelope, which protects internal components from contamination and environmental stress. It is actuated magnetically either by an electromagnet or a permanent magnet and is typically used alongside coils in automation circuits for silent switching operations.

The mechanical life expectancy of 10^8 operations and fast switching characteristics including a maximum release time of 30 microseconds and operating time including bounce of 0.25 milliseconds make it ideal for precision control equipment. It is designed with wire terminals and is optimized for PCB mounting, with compact dimensions of 13.5 mm length and 1.8 mm width.

Operating temperature ranges from -55°C to 125°C, allowing the component to be used reliably in harsh industrial environments. The switch complies with ISO standards ensuring manufacturing quality and consistency. This product is sourced from the Netherlands, reflecting its high manufacturing standards.

Assemtech RI-27AAA reed switches are widely used in industrial automation systems, electrical instrumentation, measurement devices, and HVAC controls due to their durability, reliability, and precise switching performance.
