Photoelectric Slot (Sr21)

In our search to provide our customers with instrument that helps them with their needed applications, we have fabricated Photoelectric Slot (SR21) sensors for our customers. Our sensors are manufactured using superior quality raw material. These slots photoelectric sensors of the SR21 series, with 2mm slot width, are characteristics by a high 12 bit (4096 steps) resolution, a low 20Aus reaction time and a switching frequency reaching 25kHz. The setting of the switching threshold is carried-out automatically by merely pressing a push-button, or dynamically during label movement. These SR21-IR ideal with infrared emission is ideal for label or hole detection on sustained surfaces, while the SR21-RG norm with double red or green emission suits color print register mark detection on transparent films for automatic packaging.
Salient Features :-
* Teach-in setting: easy and fast setting procedure
* Dynamic setting: possibility to set the sensor while the labels film is moving
* 12 bit resolution: high detection reliability for a precise reading
* 25KHz switching frequency: high detection repeatability
* Red/Green emission model: possibility to perform contrast application
