Product Features (Bedook Fork Photoelectric Sensor FG55 6mm DC4 Wire)

The Bedook Fork Photoelectric Sensor FG55 6mm DC4 Wire is a small through-beam sensor. Key specs: 6mm fixed sensing distance for 0.8mm×1.2mm opaque objects. Operates on 5 – 24V DC ±10% with <15mA current. Dual output (Light-on / Light-shade), IP66 ingress, response time light-on <20μs, light-shade <80μs (max. 3000Hz).

1. Precise Sensing Distance: The Bedook Fork Photoelectric Sensor FG55 6mm DC4 Wire features a fixed 6mm sensing distance. This precise parameter allows it to accurately detect opaque objects as small as 0.8mm×1.2mm. In contrast to some competing sensors that may have inconsistent or less-defined sensing distances, this fixed value ensures reliable and repeatable performance. In applications such as the assembly of micro-electronic components, where precision is critical, this sensor’s accurate detection can significantly reduce errors and enhance production efficiency.
2. Wide Operating Voltage Range: Operating from 5V DC to 24V DC ±10%, it can seamlessly adapt to different power sources in various industrial environments. This wide voltage range provides a distinct advantage over many similar sensors that are restricted to a narrower voltage band. Whether it’s a small-scale production line powered by a 5V battery or a large-scale industrial plant with a 24V power system, the Bedook sensor can operate without the need for complex voltage-conversion setups, saving both time and cost during installation and maintenance.
3. Low Current Consumption: Consuming less than 15mA, the sensor is highly energy-efficient. In large-scale industrial operations where numerous sensors are deployed, this low power consumption can lead to substantial energy savings over time. Moreover, reduced current consumption results in less heat generation, which helps maintain the stability of the sensor and the overall system. This, in turn, reduces the risk of overheating-related failures and extends the lifespan of the equipment.
4. Dual Output Functions: The sensor offers two output functions: Light-on ON and Light-shade ON. This dual functionality provides users with the flexibility to customize the sensor’s operation according to their specific application requirements. For example, in a packaging line, the Light-shade ON function can be used to detect when a product passes through the sensor’s beam, while the Light-on ON function can be utilized for other detection tasks, such as ensuring the proper alignment of components. This feature is not always available in competing products, giving the Bedook Fork Photoelectric Sensor FG55 6mm DC4 Wire an edge in terms of adaptability.
5. High – Quality Ingress Protection: With an IP66 ingress protection rating, the sensor is dust – tight and can withstand powerful water jets. This makes it suitable for use in harsh environments, such as outdoor manufacturing facilities, factories with high dust levels, or areas prone to water splashes. Many competing sensors have lower protection ratings, limiting their usability in such demanding conditions. The Bedook sensor’s robust protection ensures reliable performance even in adverse environmental conditions, reducing the need for frequent maintenance or replacement.
6. Fast Response and High Repeatability: The sensor has a quick response time, with light-on <20μs and light-shade <80μs, and a maximum frequency of 3000Hz. Additionally, it offers a repeatability accuracy of <0.01mm. In applications that require high-speed and repetitive operations, such as in the automotive manufacturing industry or high-volume consumer goods production, these features are essential for real-time monitoring and control. They enable efficient production processes and help maintain high product quality.
