The Allen Bradley 45LPT-1LEB1-P4 is classified as an optical label sensor ideal for applications requiring label detection. It operates using a transmitted beam method that guarantees precise sensing. This device has an operational voltage range between 10 and 30 V, utilizing a direct current (DC) supply for functionality.

With an IP65 rating, the sensor demonstrates effective protection against dust ingress and water spray, making it suitable for use in various environments. Its sensing gap is set at 3 mm, ensuring accurate label detection within that range. Nonpulsed infrared light serves as the medium for radiation, supporting consistent operation in practical situations. For ease of use, the sensor is designed with a push button that allows for straightforward sensitivity adjustments.

The current consumption is rated at 40 mA, which is efficient for continuous operation. Additionally, this model offers excellent durability with built-in safeguards against short circuiting, overloads, transient noises, and reverse polarity, enhancing its reliability. On power-up, the unit has a delay of 350 ms to stabilize before starting operation, while its response time is notably rapid at 50 microseconds, contributing to quick sensing capabilities. Furthermore, the output type can be selected between PNP or NPN configurations, providing flexibility for integration into different systems.
