LF20-H Pressure Switch
Brand: MamcoThe LF20-H is a high pressure/low set point pressure switch for applications that see sudden pressure spikes and high pressures which can result in early switch failures.
This series has been strengthened to prevent cracking of the base with plated steel and screw machined components in a three piece design.
Modifications to the effective area of the pressure cavity, size of the diaphragm button and diaphragm o-ring are what makes the switch capable of handling sudden pressure transients and high system pressures that are common in applications such as braking, transmission and hydraulic systems.
Features- Designed to perform in higher pressure environments
- Various diaphragm materials are available to make it compatible with many mediums
- Many electrical terminations are available
- We offer an adjustment screw for fine tuning if required
- Tough, versatile choice for many OEM applications
