P1PA Luminescence Sensors. See the Invisible.

The P1PA series luminescence sensors are high-performance detectors for industrial production and quality inspection that work according to the functional principle of the reflex sensor. By emitting UV light, both visible and invisible markings from luminescent materials can be reliably detected.

Making Invisible Visible with Luminescence Sensors

The luminescence sensors are suitable for detecting markings on different surfaces and materials. The sensors work effectively even under harsh ambient conditions, such as high temperatures, and can reliably detect luminescent markings during fast processes. Thanks to the IO-Link 1.1 communication interface, the luminescence sensors can be used flexibly and enable efficient data transmission. Using a filter offers the option of restricting the detectable wavelength range and thus hiding interfering background luminescences.

High Reliability

  • Simple and reliable detection of the smallest markings, even with the lowest amounts of luminophores

  • Reliable suppression of background luminescences via filters 

  • Reliable measurement even with fast process sequences, thanks to the high switching frequency of 2.5 kHz

  • Very small visible light spot for precise positioning

  • Detection of different luminescence colors

Applications with P1PA Luminescence Sensors

Pharmaceuticals Industry

Luminescence sensors offer high process reliability thanks to a high switching frequency and reliability in the detection of luminescent markings. This ensures that packages contain leaflets or labels are applied to ampoules.

Food Industry

In canned food production, luminescent markings not visible to the human eye are applied to packaging. Luminescence sensors detect these markings and ensure that labels are applied to glass bottles, cans and other packaging.

Furniture Industry

Adhesives must be checked in order for furniture to be assembled stably. Luminescence sensors detect not only glues but also markings with fluorescent chalk, ink, oils or lubricants.

Woodworking Industry

In the woodworking industry, wooden boards are inspected for knotholes and any defects found are marked and then sawed off. Luminescence sensors detect fluorescent chalk on wooden boards regardless of the wood surface, thickness or color.

Product Overview

Wide Range of Uses with the 1P Format

The technology of the luminescence sensors is housed in the universally usable housing in 1P format (50 × 50 × 20 mm). It features a stable plastic housing with protection class IP67, which enables the photoelectronic sensors to be used even in humid environments. 

Advantages of the 1P Format for Luminescence Sensors

Simple parameterization via IO-Link for fast process data transfer

Innovative display unit for simple alignment and accurate diagnosis

Printed QR code for quick access to product information

Simple setting via teach-in for optimal adaptation of applications

2 mutually independent switching outputs

1P: One Format, a Wide Range of Functions

In addition to luminescence sensors, wenglor’s portfolio also includes five other functional principles in this format: Through-beam sensors, laser distance sensors Time-of-Flight, reflex sensors with background suppression, retro-reflex sensors for transparent objects as well as universal retro-reflex sensors all offer users a wide range of industrial automation options.
