LS-H21F-A

The LS-H21F-A is a versatile optical sensor designed for industrial automation applications. It is an integral combination of a receiver and a transmitter, and is used to detect, measure, and control distance varying objects or events. The main components of LS-H21F-A are the light source, receivers and the output control device.

The LS-H21F-A utilizes an LED light source which transmits an optical beam across a sensing range, and the receiver upon receiving the beam, detects the variations of the beam intensity, and accordingly, passes on the optimum output signal to the output device. It typically operates with different types of targets, like diffuse reflective; retro reflective; and traversing reflective.

The light source is equipped with a collimator lens that can focus the beam to a very narrow spot at a far distance, whereas the receiver is equipped with a lens that diverts the detected beam in the sensing range without any dispersal. The slim shape and light weight design makes it convenient for direct mounting on the machines and equipments.

The LS-H21F-A is extremely reliable and able to operate in severe industrial environments like extreme temperature and corrosive environment. It is also resistant to dust, dirt, and shock environment. The use of a stainless steel housing ensures protection against any chemical attack and worn-out. It also incorporates two adjustment sensors that let fine tuning of the level control output at minimal distances.

The LS-H21F-A offers a high grade switching accuracy and exceptional response time. It can be safely used under ambient light up to 40,000 Lux without compromising on its accuracy and performance. With its strong process monitoring accuracy, it is also suitable for detecting any changes in color and object size. This ensures a continuous and reliable detection even in the presence of highly reflective or transparent objects.

The major application fields of LS-H21F-A include detection of objects such as metallic objects; tools; targets; and vehicles. It is also extensively used in the industrial processes like packaging machines, conveyors, welding machines and different types of machine tools. The LS-H21F-A is also employed in applications like automatic learning, auto-feed, and sorting in assembly lines.

In summary, the LS-H21F-A is a reliable and versatile optical sensor designed specifically for industrial automation applications. Its central components, the light source, receivers and the output control device together ensure a precise and accurate detection and switching performance. The high grade switching accuracy and exceptional response time makes it suitable for a variety of application fields, ranging from packaging systems to machine tools. The slim shape and light weight design make it convenient to be mounted directly onto different machines and equipments.
