The Keyence PS-48 Reflective Sensor Head is a versatile and compact general-purpose sensor designed to meet the diverse detection needs of industrial automation. Its cylindrical form factor, paired with reliable infrared LED technology, makes it an excellent choice for integration in environments where precision, durability, and ease of use are essential.

With a detection distance of 25 mm in FINE mode, the PS-48 is capable of delivering accurate object detection in close-range applications. This makes it especially suitable for processes such as part positioning, presence/absence verification, and small component detection in assembly lines. The use of an infrared LED light source provides stable performance, allowing it to detect objects consistently regardless of surface finish or subtle environmental variations. This ensures dependable operation in settings where reliability is critical.

One of the defining attributes of the PS-48 is its rugged durability. The sensor meets the IP67 protection standard, meaning it is fully resistant to dust ingress and can withstand temporary immersion in water. This capability allows it to operate without compromise even in environments where exposure to moisture, oil, or particulates is a concern. Combined with an operational temperature range of -10 to +60 °C, the PS-48 is well-suited for tough industrial conditions, including food processing, packaging, and automotive manufacturing.

The compact cylindrical housing simplifies installation, enabling integration into confined machine spaces or retrofit applications where sensor size is a limiting factor. At only 40 g including its 2 m cable, it reduces the mechanical load on mounting surfaces and fixtures, making it easy to reposition or adjust when needed. The lightweight yet robust design ensures both versatility and stability in long-term operation.

The PS-48 also embodies Keyence’s focus on practical usability. Its straightforward reflective sensing design eliminates the need for a separate receiver, reducing wiring complexity and enabling faster setup. Maintenance is minimized due to its reliable construction and high-quality components, which contribute to long service life and reduced downtime.

In addition to its core performance, the PS-48 integrates seamlessly with Keyence amplifier units, further expanding its functionality. When paired with advanced amplifiers, it gains access to enhanced features such as adjustable response times, interference prevention, and digital filtering, allowing it to be tailored to specific application demands.

In summary, the Keyence PS-48 Reflective Sensor Head is a dependable and compact solution that combines high accuracy, robust protection, and easy installation. Its ability to perform reliably in demanding conditions makes it an indispensable tool for industries seeking efficient and long-lasting sensing technology.
