Overview

R58A sensors offer high-performance, cost-effective registration mark sensing

featuring a single emitter color and simplified sensor setup and adjustment.

The switching threshold is adjusted with a potentiometer, and two green LEDs assist

with setting the optimal threshold. Output status information is provided by an

amber output LED. Light Operate or Dark Operate is also easily selectable via the

LO/DO selection switch.

The fast 10 kHz switching frequency and 15 microsecond repeatability ensure

reliability in high-speed operations. Models are available with a parallel or

perpendicular sensing image, as well as a 20 millisecond OFF-delay to solve a variety

of applications. The rugged zinc alloy die-cast housing and high quality acrylic lens

are designed to handle ambient electrical noise and vibration from presses and die

cutting machinery.
