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. |
 |
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.
|
 |
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. |
 |
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. |
 |
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)”. |
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.
 |
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. |
 |
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.
|
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.

Thanks to construction/design, no blind zone even when two light curtains are mounted on top of each other. Beams start very close to the edges of the light curtain.
