The CON021 converter linearizes these impedance variations into a standardized negative-going output signal (-4 VDC to -20 VDC).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGap Voltage Validation:\u003c\/strong\u003e Successful integration requires validation of the nominal air gap. The converter output must be calibrated to the factory-defined negative voltage target at the nominal gap to ensure the system operates within the linear portion of its 4 mm static range. Deviation from this target indicates the probe is outside the measurement window, risking signal saturation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge Shaft Dynamics:\u003c\/strong\u003e The 32 mm probe face is specifically engineered for targets with diameters \u0026gt;= 200 mm. This large sensing area integrates the electromagnetic flux across the target surface, reducing errors associated with shaft curvature and ensuring consistent sensitivity in high-speed applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the system compatible with standard 24 VDC positive-ground power supplies?\u003c\/p\u003e\n\u003cp\u003eA: No. The CON021 requires a negative DC power rail (-23 V to -32 V). Applying positive voltage to the supply input will prevent the oscillator circuit from initializing and may trigger internal protection circuitry.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 13-meter integrated probe cable be cut or extended?\u003c\/p\u003e\n\u003cp\u003eA: No. The cable is a calibrated component of the sensor's resonant oscillator circuit. Splicing or modifying the length changes the circuit's total capacitance and inductance, which invalidates the factory-calibrated sensitivity and accuracy.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting and Alignment:\u003c\/strong\u003e Secure the probe into the bearing casing using the threaded stainless steel sleeve. Establish the nominal air gap using a non-magnetic feeler gauge. Because this system is intended for large-shaft machinery, ensure probe locknuts are torqued to prevent mechanical backing-out caused by machine casing thermal expansion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShielding and Grounding:\u003c\/strong\u003e Terminate the coaxial LEMO connector securely. Route the cable through rigid, grounded metallic conduit to suppress high-frequency electromagnetic interference. The cable shield must be terminated at the monitoring rack's instrumentation earth bus only; ensure no conductive path exists between the probe housing and the instrumentation ground at the machine casing to avoid parasitic ground loops.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Emerson Epro","offers":[{"title":"Default Title","offer_id":45149655302259,"sku":"CON021+PR6426\/010-130","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-06-01_15-55-08_b12cc80a-6d02-44e3-8f19-703148fd23af.png?v=1783059849","url":"https:\/\/www.dcssupplier.com\/ar\/products\/emerson-epro-con021-pr6426-010-130-proximity-sensors","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
