Precise and reliable object detection

(See Leuze at Machine Building North, 10 April 2025, on stand 84)

Aligning and commissioning sensors is often very time-consuming. The Power PinPoint LED from Leuze now makes this much quicker and easier. The sensors' light-emitting diode emits its maximum light power from a very small surface. The Power PinPoint LED generates a light spot that maintains its size, shape and homogeneity over the sensor's entire working range enabling simple and fast commissioning. This technology also increases process reliability through precise detection. The innovative light source is available for the first time with Leuze's new 33C and 35C sensor series as well as the 25C, 3C and 5B diffuse sensor series.

Small, bright and precise

Sensors with Power PinPoint LEDs generate a small, round light spot with sharply defined contours.

This gives the sensors extremely reliable detection capabilities and enables precise start and end detection of an object with pinpoint response behaviour during object tracking. Even small objects are optimally detected by sensors with Power PinPoint LED thanks to their precise detection capability.

Another advantage is that Retro-reflective sensors with Power PinPoint LEDs have higher function reserves for applications with small reflectors or large distances. Also, several through-beam photoelectric sensors can be used in parallel with increased detection reliability as their compact light beam minimises diffused light. The Power PinPoint LED also reduces the possibility of unwanted reflection to ensure highly reliable detection.

Power PinPoint LED in stainless-steel sensors

The Power PinPoint LED is already used in the 33C and 35C sensor series, amongst others. Both series' ranges include diffuse sensors, retro-reflective sensors and through-beam photoelectric sensors in smooth stainless-steel housings. These are particularly suitable for hygiene-sensitive production and packaging processes. Therefore, they can be used for almost all applications in harsh, wet or hygiene-sensitive environments.

The sensors can withstand high mechanical loads and intensive cleaning processes. The 33C and 35C series also include special solutions for packaging processes - including sensors for detection through film, clear glass or PET.
