Type 4 Safety Light Curtain
With the SF4B series of safety light curtains, SUNX has built off of the successful features of previous models to create an easily integrated, full featured light curtain, all within one of the smallest packages on the market.
The no dead zone design ensures that the light curtain can be placed on the inside frame of your machine, thus creating a more efficient integration, with less potential for damage to the unit from an external source.
The SF4B is available in three standard types:
- Finger Protection Type: Minimum sensing object size of 14mm (0.551") with a beam pitch of 10mm.
- Hand Protection Type: Minimum sensing object size of 25mm(0.984") with a beam pitch of 20mm.
- Arm/Foot Protection Type: Minimum sensing object size of 45mm (1.772") with a beam pitch of 40mm.
All types can be freely wired to provide either NPN or PNP transistor outputs.
High Speed Response
The SF4B series has a universal 14ms response time, regardless of the number of channels, the beam axis pitch, or the number of units connected in series. The result is a simplification of the calculation work involved in setting safety distances on your machine. The response time, coupled with the ultra small beam pitch of the finger protection type, allows for installation of the light curtain much closer to danger point than a conventional model.
Built in Safety Circuit with Muting/Blanking
By integrating all functions into the light curtain itself, no longer is there a need for expensive safety relay units or muting/blanking modules.
The on-board controller supports standard functions such as floating blanking, fixed blanking, and whole curtain muting. New to the SF4B is a SUNX exclusive, channel select muting function which allow for the user to partially mute the curtain if the object that is passing through does not take up the entire length of the curtain. Also included is a muting override function that allows for easy removal of the work piece in the event that power is lost during muting.
All muting/blanking functions are easily configured using the SFB-HC Handy Controller. In addition, the SFB-HC can also control the light emission intensity, password protect against unauthorized changes, and easily copy settings to other light curtains.
ELCA Function
The SF4B also incorporates an advanced interference prevention system that not only cancels the effect of high intensity extraneous light but also avoids mutual interference with other units by shifting the scan timing of the light curtain.
Easy Maintenance
The SF4B is equipped with an easy to read digital error indicator that makes troubleshooting extremely simple.
SUNX also provides a number of convenient mounting options as well as an available protection bar that offers added resistance to external impact.
Optional Control Unit
SUNX offers four optional control units.
- Plug-in Type Control Unit SF-C11: Provides quick connection with a removable terminal block.
- Robust Type Control Unit SF-C12: Provides a metal, IP65 rated enclosure for stand alone setup without the need for housing in a control panel.
- Slim Type Control Unit SF-C13: With only a 22mm thickness, this control unit can be placed in even the smallest control boxes.
- Application Expansion Unit SF-C14EX: Contains functionality for muting, an emergency stop switch, and utilizes semiconductor outputs. Also allows for independent control of three safety circuits so that equipment could be shutdown partially or completely.
