Ingression Protection for Solenoids

Ingression protection is a commonly requested solenoid feature. As dirt, dust, moisture, and other foreign objects accumulate in a solenoid, the performance and life cycle are dramatically reduced. There are several methods to combat ingression, but before choosing the correct solution it is important to understand the degrees of protection available. International Protection (or IP)

Solenoid Troubleshooting

While Magnet-Schultz of America designs solenoids to perform above and beyond the expectations of its customers, there are constraints to the capabilities of any given design. Environmental factors, power supply errors, and general lifecycle wear can all lead to solenoid failures. This guide outlines some of the common failure modes, and should assist in

Solenoid Valve Types

The latest entry in the Magnet-Schultz of America Solenoid 101 blog series is designed to explain the basic differences between common solenoid valve designs. This blog builds on our general overview of solenoid principles. Check our blog history for information on more technical concepts and feel free to make suggestions for future posts. Solenoid

Hydraulic Solenoid Design Features

In pt. 1 of our hydraulic solenoids post, we described how they differ from electromechanical solenoids and discussed some basic applications. We also had a follow-up blog post that described the two major functional categories of hydraulic solenoids, on/off and proportional. This post will expand on the different design and manufacturing features of tubes

Solenoid 101: What is a Solenoid?

Magnet-Schultz of America’s new Solenoid 101 series of blogs is designed to inform about the basic functions of solenoid products. We will start by tackling the fundamentals of solenoid terminology, function, and design. Future posts in the series will describe other MSA product categories and applications in a similar fashion, providing a quick and easy
