Magnetic Switches: Maintenance-Free & Reliable.
XSZ magnetic proximity switches are the pinnacle of non-contact position detection. Engineered with hermetically sealed contacts, they operate seamlessly in oil, water, and dusty environments where optical sensors fail.
The Power of Magnetic Fields
Unlike standard proximity sensors, magnetic switches utilize the flux of a permanent magnet to trigger contacts. This allow for sensing through non-magnetic barriers with absolute precision.
Barrier Penetration
Magnetic fields can pass through all non-ferromagnetic materials. XSZ sensors can detect a target even if it is behind a wall of:

The Variable of Detection Distance
Unlike inductive sensors, the sensing range Sn of a magnetic switch is a function of the actuator's magnetic field strength. Selecting the right magnet material is key to performance.
Factors Influencing Sn
The stronger the magnet's remanence (Br), the further the sensing distance.
Sensitivity varies depending on whether the magnet approaches axially or laterally.
Non-ferrous barriers (Aluminum/Plastic) have zero impact, while iron plates will shield the field.
Field strength B decreases in inverse proportion to the cube of distance d.
Magnet Material Comparison
Maximum power in minimum size. Best for micro-sensors where space is limited but long distance is required.
Superior temperature stability (up to 500°C). Preferred for aerospace and foundry applications.
Economical choice for large-scale security and gate sensing where extreme distance is not critical.
Proven in Extreme Environments
From deep-sea exploration to high-speed automation, XSZ magnetic sensors provide the "silent reliability" that critical infrastructure demands.
Pneumatic Cylinder Feedback
Designed to fit standard T-slot and C-slot tracks. Our sensors detect the magnetic ring on the internal piston through the aluminum cylinder wall, providing 100% accurate end-of-stroke signals.
Elevator & Hoist Leveling
Utilizing Bistable Logic, these sensors are ideal for floor leveling. They maintain their state even after a power loss, ensuring the elevator car stays safely positioned relative to the floor magnets.

What Our Global Partners Say
From pneumatic cylinder control to elevator positioning, XSZ magnetic proximity switches are the industry benchmark for non-contact reliability and extreme longevity.
"We replaced our old mechanical limit switches with XSZ hermetically sealed reed switches. After 50 million cycles on our assembly line, they still perform with zero drift. The non-contact design has completely eliminated our maintenance downtime."
"The ability to sense through stainless steel walls is a game-changer for our food processing tanks. XSZ's high-sensitivity magnetic sensors detect the internal float perfectly through the 3mm casing, maintaining a total vacuum seal."
"XSZ's universal C-slot sensors fit our pneumatic cylinders perfectly. Sourcing directly from the factory not only improved our margins but gave us access to custom sensitivity tuning that local distributors simply couldn't provide."
Frequently Asked Questions
Expert insights into the selection, installation, and optimization of XSZ magnetic sensing solutions.
What is the advantage of a magnetic switch over an inductive sensor?
While inductive sensors detect any metal, magnetic switches only react to magnetic fields. This allows them to "see through" non-ferrous barriers like stainless steel, aluminum, and plastic. Additionally, magnetic switches typically offer much larger sensing distances relative to their housing size.
Should I choose Reed or Hall-effect technology?
Choose Reed Type if you need a passive sensor (no power required), high-voltage switching (up to 250V), or simple two-wire logic. Choose Hall-effect for high-speed counting applications, as they are solid-state with no moving parts, offering infinite mechanical life and frequencies up to 1,000 Hz.
Why is my sensing distance ($S_n$) inconsistent?
In magnetic sensing, $S_n$ is directly proportional to the magnetic flux ($mT$) of your actuator. If the distance is too short, you may need a stronger magnet (e.g., switching from Ferrite to Neodymium). Also, ensure the magnet is approaching the sensor's sensitive axis; lateral approach usually results in a shorter range than axial approach.
What is a "Bistable" magnetic switch?
A bistable switch maintains its output state even after the magnet has passed. It requires a reverse polarity magnet (e.g., South pole after North pole) to reset. This is a critical feature for elevator positioning and hoist limit controls to ensure safety during power outages.
Can magnetic switches operate in oily or submerged environments?
Absolutely. Because the sensing elements are hermetically sealed in glass (Reed) or epoxy (Hall) within a robust housing, our IP68-rated sensors are completely immune to cutting oils, dust, and can operate under water pressure without signal degradation.
Need help matching a magnet to a sensor?
Our engineers can calculate the required flux density (mT) based on your target air gap and material barriers.
