Optical Sensors are devices used to detect and measure incoming light to interpret the information or convert into a usable format. Photointerrupters, also known as light-activation switches, are among the most common types of optical sensors and are widely used in a variety of applications. Slot Type Photointerrupters are particularly useful in applications that require precise detection of a linear target in an automated system. One such example is the HOA0961-N55 optical sensor, which is a logic-output type photointerrupter with a slot width of 0.6mm and a slot pitch of 1.5mm.

This type of optical sensor is usually employed in the automatic operation of machinery and industrial equipment, such as motorized drive systems, robotics, and factory automation. It is designed to detect the presence of an object or a change in a linear target such as a paper web, a metallic tape, or a conveyor belt. Its working principle is based on an “interrupter” output that registers the interruption of light in the slot when an object moves across the opening. The output signals can be used to control the speed, position, and segmentation of the item.

The HOA0961-N55 is based on NPN Output Photointerrupter technology and comprises an LED source, receiver, and amplifier. The LED illuminates a slot and the receiver detects the amount of reflected light. When an object passes through the slot, it interrupts the light and the receiver output level changes accordingly. The amplifier amplifies this signal to produce a digital output compatible with CMOS/TTL circuits. The output voltage range is 0V-6V, with 3V being the switching voltage threshold. This means that when an item passes through the slot, the output voltage changes from 0V to 6V, and when the slot is clear, the output voltage is 3V.

The main features of the HOA0961-N55 include high sensitivity, low transmitting power consumption, a compact size, and high precision in detection. It is also highly reliable, with a life expectancy of up to 10 million operations. Its wide operating temperature range (from -30°C to +90°C) and wide operating power voltage (from 6V to 36V) further enhances its functional use.

In conclusion, the HOA0961-N55 is a powerful, reliable, and efficient optical sensor that can be used in a variety of applications. It has an outstanding detection accuracy and is rugged enough to withstand extreme operating conditions. It is also cost effective and relatively simple to install and maintain.
