Available. The Keyence LV-21AP is a main amplifier unit in the LV series of digital laser sensors, designed for precise distance measurement and object detection in industrial automation applications. This PNP output unit features two PNP open-collector control outputs, each capable of handling up to 30 VDC and 100 mA, with a residual voltage of 1.0 V or less. The LV-21AP offers three response speeds to suit various operational needs: FINE mode at 80 µs, TURBO mode at 500 µs, and SUPER mode at 4 ms. It supports the addition of up to seven expansion units, allowing for a total of eight units, including the main unit, to be connected. The device operates within a temperature range of -10°C to +55°C and a humidity range of 35% to 85% RH, ensuring reliable performance in diverse environments. Constructed with a polycarbonate main unit and housing, the LV-21AP weighs approximately 120 grams, making it a robust and lightweight solution for industrial sensor applications.
