Sensor Solutions' catalog offers both analog and digital output sensors for detecting the presence of steel. Analog Ferrous Metal Position Sensors provide an output that increases as steel approaches the sensor face. Digital Ferrous Metal Detection Sensors provide a digital switching output that turns on when steel is present.

Ferrous Metal Proximity Sensors
Analog Ferrous Metal Detection Sensors
Analog Ferrous Metal Position Sensors provide a single analog output that increases as steel approaches the sensor face.
- 275VPA sensors output tracks a large steel plate over 3/8” of travel with our standard programming and can be custom programmed to detect specific targets over a gap range for tracking changing proximity.
Digital Ferrous Metal Proximity Sensors
Digital Ferrous Metal Detection Sensors provide a digital output that turns on when detecting the presence of steel.
- 275VPD sensors' output detects a large steel plate at 3/8” with our standard programming, but can be custom programmed to detect specific targets at a precis
Which Ferrous Metal Detection Sensor is Right for your application?
The output of these sensors is precise and repeatable at the same gap even when temperatures change. They can be custom programmed for high precision applications and the sensors can be built in a wide variety of packages. When the application requires a simple indication that a steel target is present or not then the 275VPD digital switch is the appropriate choice.
If the application requires tracking the gap between the sensor and target the analog 275VPA sensor output will start to increase as the target approaches and the analog output is proportional to that gap.
Both sensor types are able to see steel targets through non-ferrous materials such as aluminum, brass, plastic, and some grades of Stainless Steel.
