Functional Features The Proximitor Sensor features a thin design for high-density DIN-rail installations. The mounting base provides electrical isolation. Improved RFI/EMI immunity achieves CE mark approvals without special mounting considerations. SpringLoc terminal strips facilitate robust field wiring. The multiple agency approvals enable global deployment. The 9.0 meter system length accommodates remote installations.
Application Scenarios Hazardous area control cabinet installations, regulated industry machinery monitoring, offshore platform DIN rail systems, petrochemical processing control rooms, power plant distributed monitoring, nuclear power plant condition monitoring, global industrial facilities requiring agency approvals.
Performance Parameters The sensor delivers 3.94 V/mm sensitivity with linearity within ±0.10 mm over the 4.0 mm range. The frequency response extends from 0 to 10 kHz. The multiple agency approvals cover intrinsically safe and non-incendive installations. The DIN rail mount maintains full electrical performance.
Material Composition The housing is constructed from nickel-plated aluminum. Connectors are gold-plated brass. Terminal strips feature SpringLoc design.
Structural Characteristics The sensor features a compact, thin housing optimized for DIN rail mounting on standard 35 mm DIN rail. The mounting base provides electrical isolation. The sensor includes coaxial system connectors for probe and extension cable connection.
Working Principle The Proximitor Sensor generates a high-frequency RF signal transmitted through the 9.0 meter cable system to the probe tip. Eddy currents induced in the conductive target surface modify the RF field. The sensor detects these modifications and outputs a DC voltage proportional to the gap distance.
