The integrated 1.0m cable must combine with a 4.0m cable to maintain the required 5.0m total system electrical loop tuning.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat does the \"CN\" suffix indicate at the end of the part number?\u003c\/p\u003e\n\u003cp\u003eThe \"CN\" designation signifies NEPSI and CCC explosion-proof certifications, required for intrinsically safe industrial applications within China.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the standard output scale factor of this proximity sensor loop?\u003c\/p\u003e\n\u003cp\u003eThe nominal scale factor is 7.87 V\/mm (200 mV\/mil) when paired with a matching 3300 XL extension cable and Proximitor sensor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhy choose the unarmored cable option (\"02\") over an armored option?\u003c\/p\u003e\n\u003cp\u003eThe unarmored cable provides a tighter bend radius and smaller outer profile, making it ideal for routing through existing rigid or flexible field conduits.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the minimum bend radius for this unarmored coaxial cable?\u003c\/p\u003e\n\u003cp\u003eMaintain a minimum bend radius of 25.4 mm (1.0 inch). Kinking the cable past this limit permanently degrades structural impedance, causing severe calibration tracking errors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes this proximity probe require routine calibration fields adjustments?\u003c\/p\u003e\n\u003cp\u003eNo. The 3300 XL series features complete factory interchangeability. As long as the total system loop length is maintained, you can swap components without field tuning.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat target material is this proximity probe calibrated against?\u003c\/p\u003e\n\u003cp\u003eIt is factory-calibrated against AISI 4140 electric steel. Target metals with higher chromium or aluminum content will alter the sensor's scale factor accuracy.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow can I identify a probe circuit failure using a digital multimeter?\u003c\/p\u003e\n\u003cp\u003eMeasure the DC voltage across the Proximitor Sensor's output terminals. A reading near 0 Vdc points to a shorted line, while -24 Vdc indicates an open loop or a cut cable.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518847180973,"sku":"330104-00-22-10-02-CN","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330104-00-22-10-02-cn-3300-xl-8-mm-proximity-probes-qilu5fio4gc.jpg?v=1766980345","url":"https:\/\/www.maxwellplc.com\/products\/330104-00-22-10-02-cn-bently-nevada-3300-xl-proximity-probes","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
