โฟโต้สวิตช์แบบทรงสี่เหลี่ยม
Square Photo Switch
รุ่น E3JM
คุณลักษณะ
สามารถใช้ในงานอุตสาหกรรมได้ทุกประเภท เช่น ตรวจนับวัตถุที่ถูกมีการเคลื่อนไหวโดยรอก,ใช้ในการกันประตูลิฟท์หนีบ,งานล้างรถหรือล้างขวด ลอกป้ายฉลาก,ตรวจนับห่อสินค้า,กำหนดรถยนต์อยู่ตรงตำแหน่งที่จะพ่นสี,ตรวจดูสินค้าว่ามีจุกฝาปิดทุกขวดหรือเช็คฝากล่องปิดทุกกล่องหรือไม่,ตรวจดูว่าแก้วพลาสติกคว่ำหรือหงาย เป็นต้น
