15089178 SR21 - Slot Sensors หรือ Fork Sensor ความเร็วสูง 25 KHz มาพร้อมรุ่น Infrared สำหรับใช้ตรวจจับ Label or Hole Detection โดยเฉพาะ และยังมีรุ่นที่มี Red/Green light emission สำหรับตรวจจับMarkบนแผ่นฟิล์มใสได้อีกด้วย

SR21 – Slot Sensor or Fork Sensor

INFO
The slot photoelectric sensors of the SR21 series, with 2mm slot width, are 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 (or other reference) movement.

The SR21-IR model with infrared emission is ideal for label or hole detection on continuous surfaces, while the SR21-RG model with double red or green emission suits color print register mark detection on transparent films for automatic packaging.

FEATURES & BENEFITS
• High 25 kHz switching frequency : high detection repeatability
• IR or red/green light models
• Detection of semi-transparent labels
• Detection of register marks on transparent objects
• 4 wire anti-valent NPN and PNP output
• 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

APPLICATIONS
This product series has been developed to satisfy to requirements of the following reference applications:
• Packaging lines
• Labeling machines
• Paper and Printing machines
