Core Product Features: Precisely Match 433MHz Scenarios, Balancing Performance and Environmental Adaptation

1. Electrical Characteristics: 433MHz Frequency-Optimized, Low-Loss Transmission for Stability

• 433MHz Dedicated Coverage: Operating frequency locked at 433MHz, precisely matching global ISM (Industrial, Scientific, Medical) band and typical IoT (Internet of Things) applications. Compatible with mainstream 433MHz scenarios like wireless meter reading, smart home remote control, and industrial sensors. No need to replace antennas due to device frequency differences, ensuring strong adaptability.
• Low VSWR for Efficient Transmission: Voltage Standing Wave Ratio (V.S.W.R) <1.7, combined with 50Ω standard input impedance, minimizes signal reflection loss and ensures efficient energy transmission. The -3 dBi gain adopts vertical polarization design, enabling more balanced vertical signal penetration and coverage in environments such as multi-wall homes and complex industrial layouts, avoiding unstable reception caused by "fast signal attenuation".
• High Power Stable Capacity: With a power capacity of 50W, it supports stable operation of high-power 433MHz devices such as industrial wireless data radios and high-power remote control terminals. Even when batch sensors (e.g., 200+ temperature and humidity sensors in a factory) transmit data simultaneously, it can avoid performance degradation caused by power overload.

2. Mechanical Characteristics: Lightweight ABS Material, Flexible Installation and Easy Integration

• Mini Size for Easy Embedding: Overall dimension is 108mm×7mm (about a quarter of palm length × thickness of a thin pen), with a weight of only 7.38g (about the weight of 2 coins). It can be easily embedded into the casings of smart meters, small remote control terminals, industrial sensor nodes, etc., perfectly adapting to the "miniaturization + high integration" design trend of IoT terminals.
• Customizable SMA-J Male Connector: Adopts SMA-J Male connector (customizable). Screw-on mounting ensures tight engagement (fitting tolerance ≤0.02mm) for smooth plugging and firm connection, avoiding 433MHz signal disconnection due to loose interfaces. The cable-free design (Cable Type/Cable Length is "-") allows direct docking with the device's SMA female socket, simplifying the installation process and enabling flexible cable length matching as needed.
• Durable ABS Material: The main body is made of ABS engineering plastic, which has excellent impact resistance and aging resistance, and can withstand scenarios such as outdoor wind and sun, and collisions during device installation and removal. The smooth surface is easy to clean, and dust or slight oil stains can be wiped directly, suitable for industrial workshops, home environments, outdoor monitoring stations and other scenarios.

3. Environmental Characteristics: Ultra-wide Temperature Range + Environmental Compliance, Reliable Operation in All Scenarios

• Extreme Temperature Adaptation: Both operating and storage temperature ranges are -45~+85℃, enabling stable operation in extreme environments such as extremely cold winters in northern regions (-40℃), hot summers in southern regions (+70℃), and industrial cold storage (-30℃), without additional temperature control measures. It is suitable for global multi-scenario deployment in high-latitude areas, plateaus, high and low temperature workshops, etc.
• RoHS Compliance for Eco-friendliness: Strictly RoHS compliant, free of harmful substances such as lead and cadmium. It can be safely used in home smart devices, medical monitoring terminals, and food industry sensors, completely avoiding compliance restrictions in international procurement.

Core Advantages: Focus on "Dedicated Frequency, Stability, Easy Deployment"

• "433MHz Dedicated" High Adaptation Precision: Deeply optimized for the 433MHz frequency band, a single antenna can match core scenario devices such as wireless meter reading, smart home, and industrial sensing, greatly reducing the complexity of inventory across scenarios and regions. It is especially suitable for IoT solution providers and smart device manufacturers to carry out large-scale projects.
• "Low VSWR + High Power" More Stable Transmission: VSWR <1.7 effectively reduces signal loss, and the 50W power capacity supports high-load transmission. In complex electromagnetic environments such as multi-device interference at home (e.g., simultaneous operation of smart lights, curtains, and meters) and large-scale sensor networking in factories, it can still ensure that data (such as electricity consumption data and equipment vibration information) is transmitted without packet loss and accurately, improving system reliability.
• "Lightweight + Customizable Interface" More Flexible Deployment: The mini size and lightweight design can be seamlessly embedded into various 433MHz terminal devices. The SMA-J male connector supports customization and easy installation. From municipal batch deployment of wireless meter reading systems, enterprise integration of industrial data transmission modules, to personal DIY smart home devices, installation and adaptation can be completed quickly.

Multi-industry Application Scenarios: Covering Core Needs of 433MHz Wireless Communication

• Smart Metering: Remote Metering for Power/Water. Compatible with 433MHz smart electricity and water meter data collection modules, the antenna is embedded into the meter casing via screw mounting. The low VSWR ensures that the meters can stably upload electricity and water consumption data to the meter reading platform in the dense electromagnetic environment of residential buildings, replacing manual meter reading, improving meter reading efficiency and data accuracy, and helping the intelligent upgrade of the power and water industries.
• Smart Home: Wireless Control of Whole-house Devices. Matched with 433MHz smart home gateways (such as central control terminals supporting multi-device remote control), the antenna does not occupy extra space after folding and storage. Vertical polarization and omnidirectional radiation enable signal coverage in every corner of the home, ensuring that smart lights, curtains, air conditioners, security cameras and other devices are stably networked through the 433MHz network, avoiding the failure of automated scenarios caused by "device offline" and enhancing the smart home experience.
• Industrial IoT: Remote Monitoring of Equipment Status. Used in 433MHz machine tool vibration and temperature/humidity sensors (factory equipment health monitoring terminals), the antenna is mounted on the equipment casing (108mm length does not occupy production line space). ABS material is resistant to machine tool oil and mechanical vibration, and the -3dBi gain vertical polarization enables stable signal transmission along the vertical direction of the equipment. The temperature resistance of -45~+85℃ adapts to workshop temperature changes, ensuring that data such as bearing vibration frequency and equipment temperature are transmitted to the industrial cloud platform in real time, helping predictive maintenance and reducing production line downtime risks.
• Outdoor Monitoring: Environmental and Security Sensing. Matched with 433MHz outdoor environmental monitoring sensors (such as weather stations, security infrared detectors), ABS material is resistant to outdoor sun and rain, and the temperature resistance of -45~+85℃ resists day-night temperature differences in plateau areas (night -15℃, daytime +25℃). Omnidirectional radiation ensures that sensors can stably transmit signals such as temperature, humidity, and intrusion alarms to remote gateways in the wilderness, providing reliable data support for agricultural meteorological prediction and scenic spot security management.
• Consumer Electronics: Signal Enhancement for Remote Control Devices. Compatible with 433MHz wireless remote controls (such as garage door and electric curtain remote controls), the low VSWR characteristic of the antenna improves the transmission efficiency of remote control signals. Even in large-sized homes with multi-wall barriers, stable control over long distances (≤100 meters) can be achieved, solving the pain point of traditional remote controls "failing through walls".
