Fixed-Focus Blue Light Sensors Integrate Smart Communication Capabilities

SensoPart is releasing updated DTECT Presence series Fixed-Focus sensors featuring BlueLight technology and newly added IO-Link capabilities for industrial automation applications. The integration provides advanced parameter configuration and diagnostic data for automated labeling and cosmetics packaging processes without requiring complex teach-in procedures.

Dual-Mode Operation and Process Transparency
The optical detection units operate in either standard input/output (SIO) mode or IO-Link mode. In SIO mode, the hardware functions automatically using preset switching points, maintaining a tamper-proof mechanical design devoid of external operating buttons. When switched to IO-Link mode, the smart sensor ecosystem enables operators to access continuous diagnostic data, including signal quality feedback that indicates detection stability. This dual functionality ensures process transparency while preventing unintentional changes to established settings. This mechanical security is critical for standardized machine series applications, where sensor replacement must occur rapidly without requiring product-specific knowledge or the repetition of teach-in sequences.

BlueLight Technology and Optical Optimization
Designed for challenging optical tasks, the sensors utilize short-wavelength blue light emission to detect materials that typically absorb standard red light. This mechanism makes the devices suitable for identifying black, highly glossy, and semi-transparent targets, such as the clear films frequently utilized in automated labeling processes. Coinciding with the IO-Link integration, the light spot geometry has been expanded. The larger emission spot averages out minor surface irregularities, resulting in more stable and reliable object detection under variable environmental conditions.

Decentralized Smart Functions for Edge Processing
The inclusion of the IO-Link protocol introduces logic processing directly at the sensor level. Available smart functions include On and Off Delay timers, as well as an internal counting mechanism. These features allow control engineers to adapt the hardware to specific application timings and throughput requirements, shifting basic data processing away from the central programmable logic controller while retaining the underlying fixed-focus commissioning model.

Additional Context
This section details technical specifications and competitive benchmarking not included in the original news release.

In the industrial automation market, blue light photoelectric sensors are specifically positioned against standard red light and laser sensors. Competitors such as Sick and Baumer offer similar IO-Link-enabled blue light devices designed for highly light-absorbing or angled reflective surfaces. The standard benchmark for these sensors involves the absorption rate of the target material; blue light, emitting at a wavelength of approximately 450 to 460 nanometers, scatters more effectively on dark or porous surfaces compared to standard red light at 650 nanometers. This yields a higher energy return to the receiver array. While laser sensors offer smaller spot sizes for micro-parts, the expanded light spot geometry of fixed-focus blue light sensors provides superior reading stability when scanning textured, glossy, or irregular packaging materials.
