Product Description

The KEYENCE LV-N11P is a compact, high-performance digital laser sensor amplifier designed for precise distance measurement and position detection in industrial applications. It features two PNP open collector outputs with selectable Light-On/Dark-On modes, and supports various timer functions including OFF, ON-delay, OFF-delay, and one-shot, with adjustable durations from 1 ms to 9,999 ms. The amplifier offers a high-speed response time of 80 µs in High-Speed mode, making it suitable for dynamic detection tasks. Its robust design includes reverse polarity protection, over-current protection, and surge absorption, ensuring reliable operation in demanding environments. The LV-N11P operates on a 24 VDC power supply and can be expanded with up to 17 units, facilitating scalable solutions for complex systems. Its compact dimensions (H 32.6 mm × W 9.8 mm × L 78.7 mm) and lightweight design (approximately 75 g) make it ideal for integration into space-constrained setups.
