Functional Features The Proximitor Sensor features a thin design optimized for high-density DIN-rail installations. The mounting base provides electrical isolation and eliminates the need for separate isolator plates. Improved RFI/EMI immunity achieves CE mark approvals without special mounting considerations. SpringLoc terminal strips require no special installation tools. The sensor is fully interchangeable with other 3300 XL 11 mm components.
Application Scenarios Modern control cabinet installations, high-density machinery monitoring systems, large turbine generator remote monitoring, distributed control system integration, industrial automation panels, compressor monitoring in control rooms, pump monitoring systems with DIN rail architecture.
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 DIN rail mount configuration maintains full electrical performance. The 9.0 meter system length accommodates remote installations.
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. The mounting base clips onto standard 35 mm DIN rail. The housing shares an identical 4-hole mounting footprint with older Proximitor Sensor designs for backward compatibility. The sensor includes coaxial system connectors.
Working Principle The Proximitor Sensor generates a high-frequency RF signal transmitted through the cable system to the probe tip. Eddy currents induced in the target surface modify the RF field characteristics. The sensor detects these modifications and outputs a DC voltage proportional to the gap distance.
