The EX-416 serves as a specialized cylinder-threaded inductive displacement monitoring probe, functioning as an all-weather metal thickness and position tracker within automated processing lines.
Compact and highly robust cylindrical body
It boasts an ultra-high data resolution of 0.04% FS at full scale
Extreme immunity in harsh workshop environments
The EX-200 Series tracks target displacement with a resolution of 0.04% F.S. (2 µm with the EX-416 sensor head). The dual analogue outputs (voltage and current) enable direct connection to external monitoring equipment. In terms of data output and downstream system architecture, the EX-200 Series tracks target displacement with a fine resolution of 0.04% of Full Scale (which equates to exactly 2 µm when operating with the EX-416 sensor head).
To ensure seamless integration with other automated hardware on the factory floor, the system is configured with dedicated dual analogue outputs, supplying both voltage and current loops simultaneously. This setup allows the micron-level physical runout data captured by the forward probe to be routed directly and instantaneously into external chart recorders, PLC data acquisition cards, or central display panels, maintaining an uninterrupted stream of positional data for total closed-loop automation control across the assembly line.

Oil & Gas Extraction
Real-time monitoring of radial vibration and axial displacement on high-pressure water injection pumps and natural gas compressor bearings on offshore drilling platforms or onshore gas fields.
Refining & Petrochemical
Acts as an intrinsically safe explosion-proof barrier to monitor journal wear and dynamic rotor eccentricity of critical rotating machinery like ethylene cracking gas compressors and propylene compressors.
Thermal Power
Installed in the main bearing housings of large steam turbines and generator sets to monitor shaft expansion, rotor vibration, and axial thrust during startup phases.
Hydroelectric Power
Used for long-term continuous online monitoring of shaft runout (radial swing) on vertical main shafts of hydro-generators, guide bearings, and thrust bearing clearances.
Nuclear Power
Monitors micron-level mechanical displacement of shafts on conventional island steam turbine generator sets and main feedwater pumps to guarantee grid power continuity and safety.
Steel & Metallurgy
Online tracking of bearing pad vibration and thermal expansion displacement on high-temperature, heavy-duty, dust-heavy rotating machinery such as blast furnace blowers and large induced draft fans.
When using the EX-416 sensor, you must strictly maintain the safety clearance from non-target metals to avoid magnetic interference, and control the torque while keeping the nuts away from the front tip during M16 tightening to prevent housing deformation from crushing the internal coil.
Additionally, it is strictly forbidden to shorten or extend the built-in 3-meter cable to preserve the factory impedance match, and you must perform material compensation calibration for non-ferrous targets while routinely cleaning iron filings off the sensing face to ensure measurement accuracy within the 0 to 5 mm effective range.

Technical notes
Technical notes
The EX-416 functions as a specialized, all-weather metal thickness and displacement tracker for short-range measurements within automated processing lines. Encased in an M16 stainless-steel threaded housing with a 1.45 cm diameter, the hardware is rigidly embedded into fixed bases of stamping molds, bearing test rigs, or rolling mill streams using locking nuts. During operation, the forward-facing face interacts with nearby metallic surfaces through a localized alternating magnetic field. Within an effective stroke of 0 to 5 mm, it translates micron-level changes in physical proximity into a dedicated stream of electrical signals at a resolution of 0.04% of Full Scale. These signals route directly to a paired EX-205 or EX-V05 central junction box, capturing real-time digital readouts of sheet thickness, minute structural deflections at press bottom-dead-centers, or shaft wobble.
It is an M16 threaded high-precision inductive/eddy-current displacement sensor head manufactured by Keyence, designed for micron-level distance and thickness measurements on metallic targets.
What is the working principle of EX-416?
It operates on the eddy-current principle, where an internal excitation coil generates a high-frequency magnetic field, inducing eddy currents on a metal target's surface as it approaches, which alters the coil's impedance to deduce the distance.
What advantages does EX-416 have over optical or laser displacement sensors?
It offers non-contact measurement but is completely immune to oil, moisture, dust, and ambient light, making it ideal for harsh machining workshops where optical/laser sensors fail.
What are the specific on-site applications of EX-416?
It is primarily utilized for press mold bottom-dead-center stroke monitoring, metal sheet presence and height verification, shaft eccentricity/runout tracking, and metallic part thickness sorting.
How to properly install and secure the EX-416 sensor head?
Thread it into a mounting bracket using its M16 housing threads and lock it with the provided nuts, ensuring the front sensing face maintains a specified clearance from surrounding non-target metals.
