                      Product Overview

                      The SR21-IR is a microprocessor-based Slot Sensor with ZAMA housing, glass lens and M8 4-pole connector. The slot sensor of the SR21 series, with 2mm slot width, characterized by a high 12-bit (4096 steps) resolution, a low 20µs response time and a switching frequency reaching 25kHz. The setting of the switching threshold is carried-out automatically by simply pressing a push-button or dynamically during label movement. The SR21-IR model with infrared emission is ideal for label or hole detection on continuous surfaces.
