Product Description

Assemtech RI-27AA is a precision Reed Switch featuring a Single Pole Single Throw Normally Open (SPST-NO) contact configuration designed for reliable switching in electrical and automation systems.

This switch is hermetically sealed inside a gas-filled glass envelope, ensuring durability and consistent performance in demanding industrial, laboratory, and commercial environments. It supports a maximum switching current of 500mA and maximum switching voltage of 200 volts, with a maximum switching power of 10 watts.

The contacts are plated with ruthenium on gold, minimizing contact resistance (115mΩ) and enhancing long-term stability. It operates effectively within a temperature range of -55°C to 125°C, making it suitable for harsh temperature conditions.

The switch is designed for PCB mounting and utilizes wire terminals, allowing straightforward integration into printed circuit boards. Its compact dimensions of 13.5mm length and 1.8mm width enable usage in space-constrained electronics assemblies.

The operating time including bounce is 0.25ms, and the maximum release time is 30μs, delivering rapid response for automation and control systems. The AT value range is between 15 to 25 AT, which defines sensitivity levels for magnetically actuated operation.

Mechanical life expectancy is rated at 100 million operations, underpinning its suitability for long-term applications in industrial automation, measurement devices, and switch assemblies.

Manufactured to ISO standards and made in the Netherlands, the RI series offers options in lengths and sensitivities to cater to diverse application needs. Hermetically sealed glass envelope ensures protection and durability.

Single pole single throw normally open (SPST-NO) configuration. Plated with ruthenium on gold for low contact resistance. Wide operating temperature range from -55°C to 125°C. Fast operating and release times suitable for precise switching.

Compact size facilitates PCB mounting in tight spaces. High mechanical life of 100 million operations. Compliant with ISO standards.

This Reed Switch is ideal for use in electrical, automation, instrumentation, HVAC, and electronic security systems where reliable magnetic switching is required. EnvMart offers the Assemtech RI-27AA Reed Switch for engineers and technicians seeking quality switching components.
