Order guide

General information The laser retro-reflective photoelectric sensors PRKL 53/… 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 unit's configuration. Depending on the teach mode, the following values are possible:

For safety reasons, the laser transmitter is equipped with a monitor, which automatically switches off the transmitter in caseof a component defect. In case of failure, the yellow LED flashes rapidly and the green LED is off. The state is irreversible andthe sensor must be exchanged.

Sensor adjustment (teach) via teach button

Standard teaching for average sensor sensitivity

Press teach button until both LEDs flashsimultaneously.

Release teach button. Ready.

After standard teaching, the sensor switches for objects with a minimum size of 1mm (see table under "General Infor-mation").

If both LEDs flash rapidly after the teach-ing event, a teaching error has hap-pened. Please check the alignment of the light beam onto the reflector and carry out another teaching event.

Teaching for maximal sensor sensitivity (dynamic teaching)

Press teach button until both LEDs flashalternatingly. Sensor remains in teachingmode even after the teach button has beenreleased.

Move some objects through the light path orswing a single object slowly back and forththrough the light path.

Briefly press the teach button to terminate theteach event.

Ready.

After teaching for maximum sensor sen-sitivity, the sensor switches for objects with a minimum size of 0.1 … 0.2mm (see table under "General Information").

If both LEDs flash rapidly after the teach-ing event, a teaching error has hap-pened. Please check the alignment of the light beam onto the reflector and carry out another teaching event.

Prior to teaching:Clear the light path to the reflector!The device setting is stored in a fail-safe way. A reconfiguration following voltage interruption or switch-off is thus not required.

Procedure as for standard teaching.

Adjusting the switching behavior of the switching output – light/dark switching

Press teach button until the green LED flashes. The yellow LED displays the current setting ofthe switching output:ON = output switches on lightOFF = output switches on dark

Continue to press the teach button in order tochange the switching behavior.

Locking the teach button via the teach input

A static high signal ( 4ms) at the teach input locks the teach button on the device if required, such that no manual operation is possible (e.g., protection from erroneous operation or manipulation).

If the teach input is not connected or if there is a static low signal, the button is unlocked and can be operated freely.
