The Allen Bradley 42BT-B2LBSL-F4 is an advanced photoelectric sensor specifically engineered for applications requiring background suppression. This sensor operates effectively over a maximum sensing range of 1000 mm and delivers accurate detection using both visible red LED at 660 nm and infrared LED at 880 nm wavelengths. Its output type is notably configurable, supporting both switchable NPN sinking and PNP sourcing outputs, enhancing adaptability in various control systems.
With a rapid switching speed of 2 milliseconds, the sensor ensures timely response in dynamic environments. The device is designed to handle a load current of up to 100 mA, while maintaining a nominal supply voltage of 12 V. The operational current does not exceed 33 mA, making it energy-efficient in use. When idle, residual leakage is limited to a maximum of 0.1 mA, contributing to overall system reliability.
For fine-tuning sensitivity, the sensor incorporates a gain adjustment mechanism, which is executed manually through a 5-turn trimmer potentiometer. Constructed from polyarylate plastic, the enclosure guarantees durability and resistance to environmental factors. Moreover, the 42BT-B2LBSL-F4 has circular protection within its circuitry, preventing damage from short circuits or other electrical anomalies, while featuring one protected semiconductor output for safety. This sensor represents a robust solution for diverse monitoring and control applications.
