LIGHT CURTAIN SENSORS

Safety light curtains by Panasonic offer up to category 4 protection and are suitable for all you machine safeguarding applications. Offering units with no dead zone detection and built-in muting and blanking functions, we can provide you with a solution that is tailored to the needs of your machine.

SF4D series

FEATURES

• Type 4 with very robust aluminum housing :  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.
• Extreme long sensing range up to 15m : The SF4D series combines both a Shot and an Long mode operating range in one unit. These series designed to increase power of emitter element and high resistance to dust, dirt contributes to the reduction of maintenance frequency.
• helps to reduce the number of different models and costs.
• Status and stability indicators for easy installation and maintenance : 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.
• Integrated PNP and NPN outputs : 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.
• Complies with all common norms and standards : 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)".
• No dead zones : The SF4D inherits the no-dead 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.
• Finger, hand and arm protection type available in heights of up to 1.9m : The length of the main unit equals the protective height so that installation is possible in places where space is limited. The SF4D can be connected in series up to 5 units.
• 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.
