QSA157

QSA157 is an advanced device that has been specifically designed for applications that require a reliable logic output. This device is commonly used for a wide variety of sensing applications, such as optical detection, proximity sensing, alarm detection, and access control. The device is equipped with advanced LED technology and microprocessor, which enable it to provide a highly accurate detection with a rapid response time.

QSA157 Construction and Specifications

The QSA157 is made up of a light emitting diode (LED) and a photodetector mounted on a single module. The LED provides illumination in daytime and nighttime operations, while the photodetector captures disturbances to provide reliable switching outputs. The presence of both these components enables the device to provide highly accurate detection.The device is available in two versions, miniaturized and standard. The miniaturized version of the device is ideal for installations in tight spaces. Its dimensions are only 52.3 x 32.3 x 6.3 millimeters, enabling it to be used in tight or remote spaces. The standard version has dimensions of 60.3 x 34.7 x 10.2 millimeters, allowing for more flexibility in terms of mounting.The device operates require a supply voltage between 6 and 24 VDC and its power consumption is approximately 1 watt. It is IP67 certified and frost resistant, allowing it to be used in outdoor conditions.

QSA157 Working Principle and Applications

The working principle of the QSA157 relies on combining the light emitted by the LED with a photodetector. When an object interrupts or blocks the light beam, the photodetector captures the modulation and provides a logic output signal. This signal can be used to detect and control a variety of events, including access control, alarm detection, optical detection, and proximity sensing.The device has various applications, including but not limited to industrial automation, building automation, home automation, access control, vending machines, and safety applications. It is also commonly used in environments with limited visibility, such as during nighttime operations.
