A new compact laser sensor from Carlo Gavazzi features a fine light spot, together with a teach-in function, giving accurate and reliable detection of small detail.
It offers an attractive alternative to fibre-optic sensors, for reliable long-range detection.
Ideal for fine mechanics and microtechnology, the LD32CNB family of laser sensors from Carlo Gavazzi gives safe, highly accurate detection of slots or components down to 2mm over a sensing distance of 20-60 mm.
It features a class 2 red laser diode to generate a sensing spot of approximately 0.5mm diameter enabling the sensor to reliably detect contrast differences in the smallest structures such as thin lines, and written characters.
Similarly it is able to detect small parts that differ distinctly in colour from the surroundings such as small components or screws on PCBs.
The "teach-in" background suppression function allows the user to adjust the device's sensitivity to enable it to reliably detect and distinguish very small approaching objects from its surroundings, even in extremely confined spaces.
Carlo Gavazzi's new laser sensor family consists of a polarised retro-reflective sensor, a diffuse-reflective sensor and a background suppression sensor.
Devices are housed in a compact 12 x 32 x 20mm reinforced PMMA/ABS package.
All sensors are available with NPN or PNP output and NO or NC can be selected.
