Laser safety notices - laser class 1
General information
 The laser retro-reflective photoelectric sensors PRK3CL… have an optimized light beam propagation in the typical range of
application of 0 … 1m (not to be confused with the operating range, which is 0 … 3m in combination with a reflector
MTKS 50x50.1). This permits the reliable recognition of the smallest of parts or the positioning of objects with maximum pre-
cision across the entire area.
 For foil 6, the sensor's side edge must be aligned parallel to the side edge of the reflective tape.
 The sensor is constructed on the basis of the autocollimation principle, i.e., light being transmitted and light being received
propagate along the same light axis. This permits the photoelectric sensor to be installed directly behind small holes or dia-
phragms. The smallest permissible diaphragm diameter for secure functioning is 3mm.
 The achievable resolution depends significantly on the device setting. Depending on the teach mode, the following values are
possible:
