NL126 Series Reed Switch
The NL126 Series is a high-power reed switch designed for lamp load and general-purpose switching in industrial and high-voltage environments. With a glass body length of 20.3 mm and diameter of 2.5 mm, this SPST-NO (Form A) switch supports switching voltages up to 200 VDC / 150 VAC, currents up to 1.5 A, and a rated power of 50 W.
Its hermetically sealed construction ensures long-term reliability, while a wide range of operate sensitivities (10–50 AT) allows for flexible magnetic actuation. The NL126 is ideal for applications requiring robust performance in compact form factors.
