Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The HOA1883-011 is an Optical Sensor from Avago Technologies. It is a Photointerrupter in a Slot Type format with a Transistor Output. The sensor includes the mounting clips and a socket. It is designed to detect an interrupt in an array of moving parts. It comes with two detectors, one for ambient light and one for controlled light.

The HOA1883-011 is a photointerrupter with a small package size and durability. It has a high speed response time of 2 ìs and a power dissipation of 0.6 W. It has a high dielectric strength of 1 kVp-p and stable sensitivity with an accuracy of ±2%. The T-shape housing design is constructed in a rugged plastic materials for a durable performance. It works from a wide temperature range of -25 to +85 of temperature range.

Working Principle

The HOA1883-011 is a non-contact, electronic switch which uses a slot with two detectors connected by a transistor inside the housing. The two detectors use an LED and a phototransistor. When a light source is blocked, the phototransistor switches from its off to on state. This triggers a relay and signal output.

The HOA1883-011 features a high sensitivity, fast response time, and long service life. Its associated current can reach up to 20 mA and there is no need for any additional electrical board for its operation. It can be immersed in liquid or oil without causing damage provided the product is mounted correctly. The sensor is used in applications that require precise control, including automation, medical devices, garage door openers, robotic systems, paper feed systems and many other desktop applications.

Applications

The HOA1883-011 is designed to detect interruptions in its array of moving parts in automated and industrial machinery. This includes detecting edges or gaps in the material including paper, bottles, cans, cardboards, cardboard boxes and other types of thin materials or objects. The applications for this sensor can include paper feed systems, level switches, packaging machinery, robotics systems, automotive applications, and medical device applications as well as other machinery control and application control systems.

This sensor is compatible with PLC, I/O system, or directly interconnected with peripheral devices or machines. In addition, the HOA1883-011 has a wide light source ranging from 70 to 110 mA. It has a stable sensitivity with a good light source and high dielectric strength which makes it suitable for high shock and vibration applications. This makes the product suitable for long-term reliability and stability when used in automated systems.

The HOA1883-011 provides reliable and low cost performance. Its slot design structure and its precise and consistent detection properties make it ideal for use in a wide range of applications. It has a wide range of operating temperature, and its high speed transistor structure makes it ideal for a variety of control systems.
