Performance Parameters:
- Sensitivity: 7.87 V/mm ±5% (5m system)
- Linearity: ±1% full scale
- Resolution: 0.1 μm
- Frequency Response: DC to 10 kHz
- Output: Analog voltage proportional to gap distance
Material Composition:
- Housing: A308 aluminum
- Terminal Block: Gold-plated copper contacts
- Mounting Base: Electrically insulating composite material
Structural Features: Compact rectangular housing designed for DIN rail mounting or traditional panel mounting. The mounting base provides electrical insulation, eliminating the need for a separate insulating plate. The terminal block uses a tool-free spring-clamp design for secure connections.
Working Principle: The Proximitor contains a high-frequency oscillator that drives the probe coil through the extension cable. When the probe is near a conductive target, eddy currents induced on the target surface change the probe coil impedance. The Proximitor electronics detect this impedance change, demodulate it, and produce a DC voltage output that is linearly proportional to the gap distance. Static gap changes produce DC voltage shifts (displacement), while dynamic gap variations produce AC voltage superimposed on the DC level (vibration).
Installation Requirements:
- Mount on standard DIN rail or use panel mounting holes
- Ensure adequate ventilation for heat dissipation
- Connect extension cable to the probe input terminal
- Connect output to monitoring system (3500, 2300/20, or 1900/65A)
- Provide regulated DC power supply (-24 Vdc nominal)
- Single-point shield grounding at the Proximitor end
- Route output cables away from high-voltage power cables
Usage Notes:
- The -50 code indicates 5m system configuration; ensure total cable length matches
- Factory calibrated for AISI 4140 steel; recalibration is required for other target materials
- The -CN suffix confirms Chinese market compliance
- Verify power supply voltage is within specified range before energizing
- Do not mix XL and non-XL components without verifying compatibility
- Perform gap voltage verification during commissioning
