Frequently Asked Questions

An explosion proof cable gland securely attaches and seals electrical cables entering explosion proof enclosures in hazardous areas. It prevents explosive gases, vapors, or dust from entering the enclosure through the cable entry point, and contains any internal explosion from spreading to the surrounding atmosphere. They are essential in petrochemical plants, oil refineries, gas stations, coal mines, and any location classified as a hazardous area under ATEX/IECEx standards.

Choosing the correct cable gland requires evaluating three key factors: (1) Hazard Zone — Zone 1 areas need flameproof (Ex d) or increased safety (Ex e) rated glands, while Zone 2 areas may use Ex n (non-sparking). (2) Cable Specifications — match the gland's clamping range to your cable diameter (3mm to 50mm available). (3) IP Rating — IP66/IP67 for outdoor or wet areas. Material matters too: 316 stainless steel for corrosive coastal facilities, nickel-plated brass for inland plants. Youngly Tech offers free application assessments to help you select the perfect cable gland.

Prices range from $2.50 to $45 per unit depending on material, size, and certification. Nickel-plated brass glands: $2.50-$12. Stainless steel (316L) glands: $8-$45. ATEX/IECEx certified glands cost 30-50% more than non-certified alternatives but are mandatory for explosive environments. Youngly Tech pricing is 15-20% below European competitors with equivalent quality. Bulk orders (500+ units) qualify for 10-25% volume discounts.

Common materials include nickel-plated brass (most economical, suitable for general industrial use), aluminum alloy (lightweight, good corrosion resistance), and 316 stainless steel (best for corrosive environments such as offshore platforms, coastal installations, and chemical plants). Youngly Tech offers all three materials with full ATEX/IECEx certification.

Cable gland size is determined by the cable outer diameter and the thread size of the enclosure entry. Common thread standards include Metric (M20, M25, M32, M40, M50, M63, M75, M90), PG (PG7-PG48), and NPT (1/4" to 2"). Match the gland clamping range to your cable diameter and verify the thread matches your enclosure. Youngly Tech provides sizing charts and technical support to ensure correct selection.

Offshore oil and gas facilities require a minimum IP66 rating to withstand saltwater spray, heavy rain, and dust. For subsea or fully submerged applications, IP68 is necessary. Youngly Tech's explosion proof junction boxes offer IP67 as standard, with optional IP68 upgrades. Our 316L stainless steel junction boxes pass 1500 hours of salt spray testing (ASTM B117), ensuring long-term durability in harsh offshore conditions.

Yes. Youngly Tech offers extensive customization: terminal configuration (4 to 24 terminals, screw/spring/clamp type, 0.5mm² to 16mm² wire compatibility), enclosure material (brass, aluminum, 316L stainless steel), entry points (up to 12 entries per box with metric/NPT/PG threads), and accessories (mounting brackets, viewing windows, pressure relief valves). Custom orders have a 10-15 day lead time and retain full ATEX/IECEx certification.

ATEX is the European Union directive (2014/34/EU) mandatory for equipment sold in EU hazardous areas. IECEx is an international certification scheme based on IEC standards, accepted in 60+ countries including Australia, Singapore, and many Middle Eastern countries. Both certify equipment for explosive atmospheres but ATEX is legally required in the EU while IECEx is internationally recognized. Youngly Tech products carry both ATEX and IECEx certifications.

Zone 1 means an explosive atmosphere (gas/vapor) is likely to occur during normal operation — equipment must have higher protection (Ex d flameproof or Ex e increased safety). Zone 2 means an explosive atmosphere is unlikely and brief — Ex n (non-sparking) may suffice. For dust environments, equivalent zones are Zone 21 (likely) and Zone 22 (unlikely). Always verify your area classification before selecting equipment.

Gas groups classify explosive atmospheres by ignition characteristics. Group IIA covers propane and butane (least easily ignited). Group IIB covers ethylene. Group IIC covers hydrogen and acetylene (most easily ignited, most stringent). Equipment certified for IIC can be used in IIA and IIB areas, but not vice versa. Always select equipment rated for your specific gas group or higher.

Verify ATEX certificates on the EU NANDO database or the issuing Notified Body's website (TÜV, Baseefa, INERIS). Verify IECEx certificates on the IECEx Online Certificate Directory at iecec.org. All Youngly Tech ATEX and IECEx certificate numbers are publicly verifiable on these databases. We provide direct links to our product listings along with test reports and compliance documentation.

Mold protection monitors use high-resolution sensors (0.01mm resolution CCD cameras) to detect foreign objects, misaligned cores, or under-filled cavities in real time, stopping the molding cycle before damage occurs. Detection takes as little as 2ms. If a defect is detected, the monitor signals the injection molding machine to stop, preventing tool collision that can cost $10,000+ in repairs. Youngly Tech's monitors reduce mold damage incidents by 92% on average.

Youngly Tech monitors are compatible with all major brands: Japanese (Fanuc, Sumitomo, Toshiba), European (Engel, KraussMaffei, Arburg), and Chinese (Haitian, Chen Hsong, Yizumi). Compatibility is achieved through universal I/O interfaces (Ethernet, PROFINET, Modbus, analog signals). They support clamping forces from 50 to 5000 tons. We provide free compatibility testing for unique machine configurations.

BDS (BeiDou) is China's global satellite navigation system with 35 satellites, offering better coverage in Asia-Pacific regions. GPS is the US system with 31 satellites. Youngly Tech's BDS trackers use dual-mode (BDS+GPS) technology for 100% global coverage, providing 1cm precision for static assets and 0.1m/s velocity accuracy for moving vehicles. BDS also offers short-message communication without cellular coverage, critical for remote sites.

Yes. Our BDS/GNSS antennas feature IP67/IP68 waterproof enclosures suitable for outdoor agricultural use (autosteer tractors, sprayers, harvesters) and UAV/drone applications (surveying, mapping, precision agriculture). They are lightweight, vibration-resistant, and factory calibrated for plug-and-play integration with popular RTK receivers (u-blox ZED-F9P, Septentrio, Unicore) and flight controllers.
