Range up to 4000mm

The new diffuse reflection laser sensor PT120520 with IO-Link interface from ipf electronic achieves sensing ranges of up to 4000mm despite its compact design in M12.

 

Since the PT120520 operates according to the time-of-flight principle, object detection does not depend on the strength of the reflected light, but on its lifetime. This allows reliable background suppression to be realized. A laser diode (laser protection class 1) with non-visible infrared light with a wavelength of 880nm is used as the emitting element.

 

The advantages of IO-Link devices such as this diffuse reflection laser sensor are that they can be set very flexibly and provide useful functions. Thus, the PT120520 achieves ranges up to a maximum of 1200mm in the standard setting (short mode). Thanks to the integrated IO-Link interface, however, the diffuse reflection sensor can also be switched to long mode and then achieves considerable sensing ranges of up to 4000mm.

 

The IO-Link interface also offers further practice-oriented options, such as setting the switching hysteresis and selecting the output function of the switching output (NO/NC). In addition, the PT120520 enables other helpful functions, such as programming a switching window (area monitoring). Here, two limit values are set in the detection range of the diffuse reflection sensor, which define the range to be checked for the presence of an object.

Basic settings and functions can also be stored in the device via teach-in.

 

The new IO-Link diffuse reflection laser sensor in stainless steel housing (protection class IP65) is also suitable for use in harsh operating conditions and is designed for ambient temperatures from -10°C to +60°C.
