Description
Neodyn 125P NEMA 4 and 13 Pressure Switch stands out in the market due to its specific engineering for stability and precision. Unlike standard switches that may suffer from set point drift, the 125P utilizes a diaphragm sensor mechanism that works in harmony with the patented Nega-Rate® Belleville disc spring. This combination provides a snap-action response, resisting vibration and ensuring that the switch activates exactly when required.
Designed for versatility, this switch offers a selectable deadband ranging from 20 psig (1.38 bar) or 8%—whichever is greater—up to 45% of the set point. This makes it an ideal solution for systems where maintaining specific pressure differentials is critical to operational safety and efficiency.
The housing and construction meet NEMA 4 and 13 standards, providing protection against water ingress, dust, and oil coolants. Furthermore, the tamper-proof design ensures that once the set point is established, it cannot be accidentally altered, making it a preferred choice for safety-critical loops in industrial automation and fluid power systems.
