Overview
AKUSENSE PE1/PE2 Series Fiber Amplifier is a digital fiber optic sensor amplifier that pairs with through-beam or diffuse fiber optic probes for detection in tight or hard-to-reach spaces. A dual 4-digit LED display shows the set value (green) and current received light value (red), with four function indicators for simple setup. The PE1 series offers NPN or PNP output with red 630nm LED, while the PE2 series upgrades to red 660nm LED, up to 20kHz response (25μs) and switchable NPN/PNP/IO-Link output for smart factory integration. Light-on / Dark-on logic is switchable, with built-in ON-delay, OFF-delay and one-shot timer functions. Both share a slim 80×9.8×39mm housing and 12~24V DC supply. Sample test and bulk procurement are supported.
Key Features
