Explanation of Model Number

Product Size

B1: Upper stop-work range for sensing side

B2: Bottom stop-work range for sensing side

D: Beam space

H: Protective height

L: Total height

When D=10mm, B1=10mm, B2=35mm

When D=20mm, B1=15mm, B2=40mm

When D=40mm, B1=15mm, B2=60mm

H is protective height: H=(beams-1) *beam space

L is total height: L=A1+A2+B1+B2+H+261
