PR126 Series Reed Switch

The PR126 Series is a high-power SPST-NO (Form A) reed switch designed for line voltage applications requiring robust switching capabilities. With a glass body length of 20.3 mm and a diameter of 2.5 mm, it supports switching voltages up to 300 VAC / 200 VDC and currents up to 1.5 A, with a rated power of 70 W.

Hermetically sealed in inert gas, the PR126 ensures long-term reliability and stable performance in demanding environments. Its extended overall length of 54.0 mm and wide pull-in sensitivity range (20–50 AT) make it ideal for industrial, appliance, and control applications where high voltage and current handling are essential.
