SF4D-A8

Compact & Robust Safety Light Curtain Type 4

Slim and robust unit body resists twisting, warping and impact,The internal unit was redesigned and downsized extensively. The internal unit was downsized to less than 40% (volume ratio) as compared to the conventional model while achieving higher performance. The case structure was also optimized and offers high rigidity without any change in external dimensions. The SF4D series provides high performance and high reliability while maintaining the installation and wiring compatibility with the previous models. Completely new mounting brackets and structure. In addition to strengthening the rigidity of the mounting brackets, we have also improved the method of attachment to the safety light curtain unit.
The power of the emitter has been increased significantly. New high power optical system offering stable operation even for long distance setup The high resistance to dust and dirt contributes to the reduction of maintenance frequency. The SF4D series complies with IP67 and IP65 (IEC) as well as NEMA Type 13 (NEMA 250). Digital indicator with a numeric display of light incidence margin facilitates beam axis adjustment and preventive maintenance.
The OFF response time of the control outputs (OSSD 1, OSSD 2) of the SF4D series is 10 ms or less. Dead zoneless design enables easy calculation of safe distance.
