JWK220-A10J Proximity Sensor Product Introduction
I. Product Overview
The JWK220-A10J proximity sensor is a non-contact position detection device based on electromagnetic induction principle, designed for reliable metal object detection in industrial automation applications. Featuring a compact structure with composite housing of weather-resistant engineering plastic and metal alloy, it maintains stable operation within -25℃ to +70℃ temperature range. The built-in high-frequency oscillation circuit and signal processing module enable contactless detection through electromagnetic field variation, effectively eliminating mechanical wear issues.
II. Operational Principle
When metallic objects enter the effective sensing range, the electromagnetic field energy of the internal oscillation circuit is absorbed, causing amplitude variation. The signal processing unit converts this change into standard level signal output with ≤0.8ms response time. Offering detection distance up to 10mm (actual performance varies by application), the sensor demonstrates excellent resistance to electromagnetic interference, suitable for challenging industrial environments containing oil, dust, or particulate matter.
III. Structural Features
Cylindrical housing complies with M18×1 thread standard, delivering effective protection against dust and water immersion (descriptive statement without certification reference). Axial or radial cable outlet configurations are available with customizable cable lengths. Integrated LED status indicator facilitates on-site debugging and maintenance. Both flush and non-flush mounting options are supported to accommodate various mechanical configurations.
IV. Application Scenarios
Extensively used in automated production line positioning, machine tool position monitoring, conveyor belt object counting, and elevator leveling control. Particularly suitable for automotive manufacturing, food packaging machinery, and injection molding equipment requiring precise position detection.
V. Technical Specifications
Target Material: Ferrous/Non-ferrous metals (adjustable sensitivity)
Operating Voltage: DC 10-30V (±10%)
Current Consumption: ≤15mA
Output Configuration: NPN/PNP selectable
