Features

Compact, light weight design, and advanced functionality in one package: A new concept "Compact Light Curtain"

The SF4B-C series comes in the size of 20 (W) × 27.4 (D) mm 0.787 (W) × 1.079 (D) in, which is designed to be compact, light weight and easy to install. We offer the extensive selection of safety features including muting and blanking.

Compact profile design, maximize the machinery opening area

The SF4B-C series is designed to fit onto an aluminum frame, maximizing the machinery opening area. It can even allow zero dead zone.

■Side mounting
■The presence of light curtain does not narrow the opening area.
■The light curtain is thin, so its bulge from frame can be minimized.

*When using standard mounting brackets (optional).

Buried mounting (side)

■The light curtain fits onto frame perfectly, even in embedded installations. ■The light curtain protrudes neither into the machinery opening nor outside the frame. ■The light curtain will not be damaged due to collision with workpiece. *When using standard mounting brackets (optional).

Rear mounting

■The light curtain fits onto a 20 × 20 mm 0.787 × 0.787 inaluminum frame perfectly. ■The light curtain does not protrude from the frame. *When using standard mounting brackets (optional).

Plastic × metal

The SF4B-C series features a proprietary double structure of a "plastic body" with a "metal inner frame" which lightens the weight while maintaining the durability.

45% lighter* for easy installation in high places and when mounting long models

*SF4B-H80 versus SF4B-H80CA-J05.

Maximum protection height of 1,623.4 mm 63.913 in

Large multi-purpose indicator (SF4B-□CA-J05 only)

The SF4B-C series incorporates a large multi-purpose indicator (orange) positioned around workers’ eye level. The indicator shows the presence of the light curtain, helping to prevent unintentional beam interruption. The indicator can be used in a variety of applications such as a muting indicator and work indicator.

■Exceptional visibility with wide angle
The large multi-purpose indicator shines brightly through the plastic body to ensure exceptional visibility.

Handy-controller SFB-HC (optional) offers easy access to settings for a range of functionality

Muting control function for individual beams: Limit the muting area

(SF4B-□CA-J05 only)

The SFB-HC handy-controller (optional) allows to perform muting control for certain beams only. Since beam channels can be specified, so there is no need to install a separate guard to prevent intrusions. For example, according to the height of a sensing object, when muting control from the lowermost beam channel to the 10th beam channel is activated, the light curtain will detect any beam interruption at the 11th or higher beam channel as a human entry and stop the machinery.

Fixed blanking function: Choose active beam channels

The SFB-HC handy-controller provides a fixed blanking function that prevents control output (OSSD) from turning off even if certain beam channels are interrupted. This function is convenient for applications where an obstacle always interrupts certain beam channels. Additionally, it is safe since control output (OSSD) is forcibly turned off in the event the obstruction moves outside the detection area.

Fixed blanking function: Choose active breams

Floating blanking function: Disable unspecified beams

*The min. sensing object will change when the floating blanking function is used.

The floating blanking function allows to disable up to three unspecified beam channels. Control output (OSSD) will not turn off as long as the number of interrupted beam channels is less than the set number of beam channels. This function is convenient when an obstruction moves inside the detection area during setup changes or when loading materials within the detection area of light curtain. *The min. sensing object will change when the floating blanking function is used.
