Compact Safety Light Curtain SF4B-C

Compact Safety Light Curtain[Type4 PLe SIL3] SF4B-C

 

Features

การออกแบบโปรไฟล์แบบกะทัดรัด ช่วยเพิ่มพื้นที่เปิดของเครื่องจักรให้สูงสุด

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 safety light curtain is thin, so its bulge from frame can be minimized.
■The safety light curtain protrudes neither into the machinery opening nor outside the frame.* When using standard mounting bracketsMS-SF4BC-1(optional)

■The safety light curtain fits onto frame perfectly, even in embedded installations.
■The safety light curtain protrudes neither into the machinery opening nor outside the frame.
■The safety light curtain will not be damaged due to collision with workpiece.* When using standard mounting brackets MS-SF4BC-1 (optional)

■The safety light curtain fits onto a 20 × 20 mm0.787 × 0.787 inaluminum frame perfectly.
■The safety light curtain does not protrude from the frame.* When using standard mounting brackets MS-SF4BC-1 (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.

Maximum protective height of 1,943.4 mm 76.512 in

Despite its compact, plastic body, the SF4B-C series features a metal inner frame that increases toughness and also keeps its enclosure not to curve.
Protective heights range from 263.4 mm to 1,943.4 mm 10.370 in to 76.512 in.

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

Thanks to its plastic body, the SF4B-C series is 45 % lighter* than previous models with aluminum enclosures.
This helps to reduce the overall weight of the equipment during transport and when shipping it overseas.

Large multi-purpose indicator SF4B-□CA-J05

The SF4B-C series is equipped with the large multi-purpose indicator at the center of the unit. The indicator shows the presence of the safety 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.

Muting control function for individual beams: Limit the muting area SF4B-□CA-J05

The SFB-HC handy-controller (optional) allows to perform muting control for certain beams. Since beam channels can be specified, so there is no need to install a 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 safety 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 (optional) 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.

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

Use output and indicators to achieve preventive maintenance when the incident light intensity gets unstable

By setting the auxiliary output switching function to off or on when light reception becomes unstable, the safety light curtain provides notification in the event of a reduction in the incident light intensity due to beam misalignment or dirt via auxiliary output (non-safety output) in addition to the incident light intensity indicator.

 

Notes:
1)An incident light intensity value of 100 % refers to the threshold value at which control outputs (OSSD1, OSSD2) change from off to on.
2)Interruption of the light refers to the presence of an object interrupts beam in the detection area.
3)This setting is not available when using muting control for individual beams, fixed blanking, or floating blanking.

PNP/NPN polarity support

Since a single model number can be switched between PNP and NPN input, fewer model numbers need to be registered.

Extraneous light check & avoid (ELCA) function

The ELCA function reduces interference without an interference prevention line.

External device monitor function

External devices (such as safety relays, etc.) can be directly connected to the handy-controller without any dedicated unit, simplifying installation, reducing costs, and helping to avoid various problems.

Beam-axis alignment indicator

Beam-axis alignment indicators are indicated in 4 blocks, allowing to see at a glance where light is being received.
