Assemtech SPST-NO PCB Reed Switch 250 mA 160 V RI-03AAA

Assemtech RI-03AAA SPST-NO PCB Reed Switch is a high-quality hermetically sealed dry reed switch designed for electronic and automation applications requiring reliable low current switching.

This switch features a single pole, single throw, normally open (SPST-NO) contact configuration with two magnetically actuated reeds enclosed in a gas-filled glass envelope. It can be actuated by an electro-magnet, a permanent magnet, or a combination thereof, making it suitable for use alongside coils to detect magnetic fields when current is applied.

The RI-03AAA model supports a maximum switching current of 250 mA, a maximum switching voltage of 160 V, and a power rating of 5 W, making it ideal for low power PCB applications. The contact resistance is very low at 120 milliohms, and the contacts are plated with ruthenium on gold for enhanced durability and superior conductivity.

Operational reliability is ensured with a fast operating time including bounce of 0.1 milliseconds and a maximum release time of 70 milliseconds. Its specified operating temperature ranges from -55°C to 125°C, allowing it to perform reliably in harsh environments.

The compact design with a width of 2.54 mm and length of 14.5 mm fits easily onto PCB mounts using wire terminals. It complies with ISO standards and is built to last with a mechanical endurance of 100 million operations, perfect for industrial automation, electrical equipment, and control systems.
