Reliable Detection in Extreme Heat.
XSZ high-temperature proximity sensors are engineered for the world's harshest industrial environments. From steel mills to glass furnaces, our PTFE-cabled sensors ensure zero-drift stability up to 250°C.
Engineered for Resilience
A standard sensor fails because of thermal expansion and seal degradation. Our high-temperature series utilizes specialized materials to maintain structural and electrical integrity up to 250°C.
PTFE (Teflon) Cabling
Standard PVC melts at 80°C. We use high-purity PTFE shielding that remains flexible and chemically inert from -60°C to +250°C, preventing short circuits in the heat zone.
316L Stainless Steel
The housing is CNC-machined from Stainless Steel 316L, providing superior heat dissipation and resisting oxidation that occurs with standard nickel-plated brass in high-heat cycles.
High-Temp Potting
Internal electronics are encapsulated in a specialized thermal-expansion-matching epoxy. This absorbs the physical stress caused by rapid heating and cooling cycles.
FKM (Viton) Sealing
To prevent hot oil or steam ingress, we utilize Viton (FKM) O-rings. These maintain their hermetic seal at temperatures where standard Nitrile rubber would brittle and crack.
Precision Across Every Gradient
Don't over-specify. Choose the temperature endurance that matches your specific industrial zone to balance performance and cost-efficiency.

Thermal Separation Strategy
For applications where the sensor body is constantly exposed to extreme radiant heat, our remote electronics design ensures the longevity of the sensitive semiconductor components.
The "Split" Architecture
The system is divided into a passive sensing head and a remote evaluation unit. This allows the sensing head to operate inside the high-heat zone, while the electronics stay safe in a cooler environment.
The sensing head contains no semiconductors, making it nearly immune to thermal aging.
Sensitivity can be adjusted on the remote amplifier without entering the danger/heat zone.
Standard with stainless steel corrugated pipes to protect the connecting cable from mechanical damage.
Thriving in Hostile Zones
From molten steel to industrial drying tunnels, XSZ sensors provide reliable position feedback where standard automation fails due to thermal stress.
Steel & Metallurgy
Monitoring the position of red-hot billets on continuous casting lines. Our 250°C sensors withstand intense radiant heat and scale dust without signal drift.
Injection Molding
Detecting mold closure and part ejection in high-speed plastic injection machines. XSZ sensors handle the 150°C+ ambient heat near the hot runners effortlessly.
Glass Manufacturing
Positioning and counting glass containers directly at the forming machine exit. The PTFE-cabled sensors resist the extreme thermal cycles and lubrication oils.
Industrial Drying Ovens
Ensuring precise conveyor alignment inside paint drying tunnels. Our silicone-free versions prevent surface defects on automotive paint finishes.

What Engineers Say
"We replaced expensive European sensors with XSZ **250°C series** in our steel rolling mill. They have been running for 8 months without a single failure. The **316L housing** handles the scale dust and heat perfectly."
"The **silicone-free PTFE cables** are a must for our automotive paint drying line. No surface defects on the car bodies, and the sensors remain accurate even at the peak of the 180°C bake cycle."
Frequently Asked Questions
How do you prevent signal drift at 250°C?
+XSZ sensors use specialized **thermal compensation circuits**. Standard sensors' sensing distances shift as the internal coil expands with heat; our circuitry real-time adjusts the gain to ensure the switching point remains stable across the entire temperature range.
Is the PTFE cable resistant to industrial oils and chemicals?
+Yes. **PTFE (Teflon)** is virtually chemically inert. It resists not only extreme heat but also hydraulic oils, cutting fluids, and aggressive cleaning agents used in food and chemical processing.
Do I need extra protection for the cable in a steel mill?
+While the PTFE cable is tough, for environments with physical impact or falling debris (like steel mills), we recommend our **Stainless Steel Corrugated Pipe** version to provide mechanical armor against abrasion and heavy impacts.
What is the maximum cable length for high-temp models?
+Standard length is 2 meters, but we can provide **custom lengths up to 15 meters** or more. Note that for voltage-drop sensitive applications at extreme heat, we recommend using our split-type design with a remote amplifier.
