High functionality, IP67, type 4 light curtain with 10, 20 or 40mm beam pitch and universal 14ms response time
The SF4B series of safety light curtains, sees SUNX build upon the successful features of previous models to create an easily integrated, full featured light curtain, within one of the smallest packages on the market. The new SF4B-series (Version 2) now offers improved environmental resistance. A new design for the body and the cylindrical inner casing protecting the internal electronics, ensures the latest models conform to IP65 and IP67 standards.
The SF4B light curtain is available in three standard types:
• Finger Protection Type:
Minimum sensing object size of 14mm with a beam pitch of 10mm.
• Hand Protection Type:
Minimum sensing object size of 25mm with a beam pitch of 20mm.
• Arm/Foot Protection Type:
Minimum sensing object size of 45mm 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 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 maybe possible using a conventional model.
Built in Safety Circuit with Muting/Blanking:
By integrating all functions into the light curtain itself, there is no longer 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 agai
nst 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.
