SF4D safety light curtain

  • SF4D safety light curtain
  • SF4D safety light curtain
  • SF4D safety light curtain

New concept: both compact and robust

  • Type 4 with very robust aluminum housing
  • Extreme long sensing range up to 15m
  • Status and stability indicators for easy installation and maintenance
  • Integrated PNP and NPN outputs
  • Complies with all common norms and standards
  • No blind zones
  • Finger, hand and arm protection type available in heights of up to 1.9m

Higher stability than SF4B thanks to changes to the interior design

Compared to the SF4B<V2> series, the internal unit has been downsized considerably. The volume of the internal unit has been reduced by more than 60%. The volume gained has been used to strengthen the case structure, making it more rigid without changing the outer dimensions. This makes the SF4D compatible with the SF4B<V2> series in terms of dimensions.

Twisting- and bending-resistant design

The new interior design makes the safety light curtain more rigid and thus more robust. The SF4D does not bend or twist as easily when it comes into contact with other objects.

  1. Resists twisting!
  2. Resists bending!
  3. Resists shock!

Response time max. 10ms for a single light curtain

When only one light curtain is installed, the OFF response time of the control outputs (OSSD1, OSSD2) is max. 10ms, the fastest in its class. For multiple safety light curtains mounted in series, the response time is max. 18ms. Thanks to the fast response it is possible to mount the safety light curtain much closer to the dangerous area.

Easy calculation of safety distance thanks to special no-blind zone design

The SF4D inherits the no-blind zone design of the SF4B series. Even in an L-shaped or U-shaped layout, the beam pitch does not change (excluding finger protection type). This makes the calculation of the safety distance easier.

Impervious to liquids and dust

The safety light curtain has IP67 and IP65 (IEC) degree of protection and complies with NEMA Type 13 (NEMA: National Electrical Manufacturers Association), a standard to determine how well the enclosures of electronic components resist the infiltration of dust and moisture. For details refer to NEMA 250 "Enclosures for Electrical Equipment (1000 volts Maximum)".

Easy installation of emitter and receiver thanks to improved optical properties

Thanks to a higher emission power, the SF4D not only works reliably on shorter distances, but also covers a longer sensing range than previous models.

Sensing range

Mode Type of protection Sensing range
Short mode (default setting) Finger protection type 0 to 7m
Hand protection type
Arm / Foot protection type
0 to 9m
Long mode Finger protection type 0 to 12m
Hand protection type
Arm / Foot protection type
0 to 15m

Please note that installing the front protection cover reduces the sensing range.

Minimizing of deviations among elements

The safety light curtain is equipped with a unique element alignment technology, thus minimizing deviations in the beam axis. Additionally, the LED quality has been improved.

Digital indicator for stable light reception

The incident beam intensity indicator (also called stable-light-reception indicator) helps to adjust the beam during installation and to control the light quality during operation. The amount and quality of the light received is indicated by the LED color and a one-digit display. When the LED lights up in orange, the light is unstable. Stable light is indicated by a green LED. The numbers displayed range from 1 to 3. The higher the number, the more stable the light. This way, it is easy to discover and remove errors caused by dirt on the detection surface or beam misalignment.

  1. Incident beam intensity indicator:
    • Stable light: Lights up green
    • Unstable light: Lights up orange
    • Light blocked: Off
       
  2. Digital indicator
    • High level of light received: Displays green “3”
    • Medium level of light received: Displays green “2”
    • Low level of light received: Displays green “1”
    • Light blocked: Off

PNP and NPN polarity combined in a single model

The SF4D series combines both a PNP and an NPN transistor output in a single model. This helps to reduce the number of different models and costs.

Communication unit

The communication unit acts as an interface between a PC and a safety light curtain of the SF4D series. It has two functions: You can use it to change settings and monitor the status of SF4D safety light curtains with a PC or you can copy settings from one safety light curtain to another without a PC. The communication unit connects to the PC with a USB cable (USB2.0, A: Mini-B, not included) and to the safety light curtains with the cable attached.

If you want to use the SF4D-TM1 communication unit with a PC, you need to install the setting software “Configurator Light Curtain”, which can be downloaded for free from our website.

Degree of protection IP67, IP65 (IEC), NEMA Type 13 (NEMA 250)
Ambient temperature -10 to +55°C (No dew condensation or icing allowed), storage: -25 to 60°C
Accessories SF4B-TR14 (Test rod): 1 pc. SF4B-TR25 (Test rod): 1 pc. -

Notes:

  1. Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20°C.
  2. When the floating blanking function is used, the minimum size of the object to be sensed becomes larger.
  3. Because the control output (OSSD 1 / 2) must be OFF for at least 80ms, the ON response will be delayed more than 50ms when the light blocked time is less than 30ms.
  4. When optical synchronization is selected, if the beam axes of both the top end and bottom end are blocked, the ON response speed decreases by as much as 1 second.
