SICK (UK) has claimed that it has improved the intensity, brightness and accuracy of opto-sensor technology with the introduction of its Pin-Point LED.

The Pin-Point, which delivers performance comparable to a short-range laser scanner, will broaden the range and performance of SICK’s LED-based photoelectric switches and photoelectric proximity switches.

A new design of LED, the Pin-Point is designed to increase light spot intensity and concentrate the energy on a much smaller area.

Pin-Point offers greater functional reserves, improved detection reliability and the capacity to detect longer ranges, according to SICK.

Using the Pin-Point, SICK photoelectric switches can detect much smaller objects, down to 1mm and at distances up to 500mm, providing an alternative to laser diode photoelectric switches.

Pin-Point technology doesn’t require the safety regime required for lasers, has a wider temperature operating range and has a lifetime of typically 100,000 hours.

The Pin-Point development has reconfigured conventional LED design by removing the bonding wire at the tip of the LED, which creates a very distinctive central black spot in the emitted light and a halo of lower intensity light.

The resulting Pin-Point spot has virtually no halo effect and its homogenous intensity enables a much tighter focus.

Alignment with the sensor is simplified, the tighter spot ensures a longer range and the more concentrated light helps overcome contamination and dirt that can occur during application.
