Product Introduction
1.Core selling points of the product
Industrial wide temperature range and vibration-resistant design
Passed -40°C to +85°C extreme temperature certification (compliant with MIL-STD-810H) and IEC 60068-2-6 sinusoidal vibration test , suitable for cold chain storage and high-temperature production lines.
2. RF stability optimization
VSWR<2.0 ultra-low standing wave ratio combined with 50Ω standard impedance matching effectively reduces signal reflection loss and increases the reading distance by 20% compared with similar products.
3. Mechanical structure reinforced protection
ABS+PC mixed engineering plastic housing (UL94 V-0 flame retardant grade) with M4 stainless steel mounting screw holes to achieve impact-resistant structure and IP54 protection.
4. Accurate UHF band coverage
Supports 902-915MHz ISM band, linear polarization directional radiation mode effectively suppresses multipath interference in metal environments.
5.Fully compatible with industrial interfaces
Passed ROHS 3.0 environmental certification, standard TNC-J reverse polarity male connector, natively compatible with mainstream readers such as Zebra FX9600 and Impinj R420.
Application scenarios
1.High-density warehouse management: integrated installation of forklift arms, stable reading of UHFRFID pallet tags in metal shelf environments (ISO 18000-6C protocol)
2.High-temperature production line traceability: real-time collection of work-in-process data in the injection molding workshop (≤85°C), and tolerance of vibration interference from hydraulic equipment
3.Harsh environment asset monitoring: regular inspection of wind turbine towers (-30°C) and oilfield equipment (+70°C)
4.High-speed sorting system: conveyor belt scenario with vibration frequency ≤55Hz, tag miss reading rate <0.1% (actual measured data)
FAQ
Q: Is it compatible with the EU 868MHz frequency band?
A: This model strictly matches the FCC/ETSI 902-928MHz frequency band, and the European 868MHz needs to be customized (supporting OEM frequency point offset ±5MHz).
Q: Can it be adapted to N-type interface devices?
A: An external TNC-J to N-J adapter is required (impedance mismatch tolerance ±5%). It is recommended to use a native TNC interface reader (such as Feig LR2000).
Q: What is the optimal solution for metal surface installation?
A: Minimum spacing formula: d≥λ/4 (λ=33cm@915MHz). It is recommended to use nylon isolation columns (field strength distribution diagram is provided in the attached installation guide).
Q: What is the specific implementation standard for vibration testing?
A: Strictly follow the IEC 60068-2-6:2007 sinusoidal vibration standard (axial frequency sweep 10→55→10Hz, acceleration 2gn).
Q: Cable customization options?
A: Support RG-58C/U coaxial cable (50Ω±2Ω) 1~15 meters customization, optional PE/PVC sheath (outdoor type with UV protection layer).
Q: What are the limitations of linear polarization in dynamic scenes?
A: Linear polarization requires that the angle between the tag and the antenna polarization direction be kept ≤45°. It is suitable for fixed-direction tags and reduces the cost by 32% compared to the circular polarization solution.
