The matched CON021 converter conditions this raw high-frequency signal into a proportional 4-20 mA current output for direct TSI rack integration. Accurate eddy-current probe scaling requires proper mechanical probe alignment during field installation. Technicians execute gap voltage validation by monitoring the unconditioned DC gap voltage (aiming for standard -10 VDC targets) prior to locking down the threaded sensor probe body. This procedure maintains linear scaling across dynamic rotor excursions and optimizes cross-talk suppression between adjacent radial monitoring channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What physical parameters do the numbers \"010-040\" represent in the PR6424 probe part designation?\u003c\/p\u003e\n\u003cp\u003eA: The \"010\" suffix defines a 10 mm sensor tip diameter, while \"040\" specifies an integral coaxial cable length of 4.0 meters.\u003c\/p\u003e\n\u003cp\u003eQ: Can the PR6424 probe send linear displacement signals directly to a PLC without the CON021 module?\u003c\/p\u003e\n\u003cp\u003eA: No, the PR6424 is a passive eddy current transducer that outputs a raw high-frequency impedance signal, requiring the CON021 signal converter to generate a standardized 4-20 mA process loop output.\u003c\/p\u003e\n\u003cp\u003eQ: How do environmental conditions affect the PR6424 probe tip versus the CON021 converter housing?\u003c\/p\u003e\n\u003cp\u003eA: The stainless steel PR6424 probe tip withstands fluid exposure and high ambient temperatures up to +180 deg C inside machine casings, whereas the CON021 converter installs in a mild cabinet environment between 0 and +65 deg C.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the CON021 converter module onto a standard 35 mm DIN rail inside a protective cabinet junction enclosure. Thread the PR6424 probe body into the machine casing bracket, using a calibrated feeler gauge or multimeter to adjust probe clearance until reading the specified DC voltage gap setting (typically targeting -10 VDC).\u003c\/p\u003e\n\u003cp\u003eConnect the 4.0-meter integral probe cable to the CON021 input terminal block without coiling excess cable tightly, keeping minimum bend radii above 30 mm to preserve coaxial shield impedance. Route output 4-20 mA signals using twisted-shielded pair wiring, terminating the shield conductor strictly at the main cabinet ground bar to block ground loop noise and EMI interference.\u003c\/p\u003e","brand":"EPRO","offers":[{"title":"Default Title","offer_id":51218029609272,"sku":"CON021+PR6424\/010-040","price":256.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/CON021_PR6424010-040.jpg?v=1759998564","url":"https:\/\/www.automodulexpert.com\/products\/epro-con021-pr6424-010-040-eddy-current-proximity-sensors","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
