The Omron F3SJ-A0785P20 represents a sophisticated solution for hand and arm protection applications as an advanced safety light curtain. Constructed to detect the presence of opaque objects as small as 20 mm in diameter, it employs an array of 52 beams configured with a beam gap of 15 mm. The effective protective height of this model is 785 mm, ensuring it safeguards the defined area efficiently.
This unit operates with a voltage rating of 24 Volts DC, permitting a tolerance of ±20%, while ripple current must not exceed 10%. The F3SJ-A0785P20 is also rated at IP65, providing resistance to dust and water ingress, making it suitable for a range of environments.
The environmental resilience of this light curtain is adaptable to an operating temperature range between -10°C to 55°C without the formation of ice. It can be stored at temperatures as low as -30°C up to 70°C. Humidity levels during operation can safely reach between 35% to 85%, while the storage condition allows for a broader humidity range of 35% to 95%, also without condensation.
In terms of performance, the unit has rapid response times, transitioning from ON to OFF in approximately 13 milliseconds and OFF to ON in about 52 milliseconds. Furthermore, its design complies with safety category PLe and Safety Category 4, ensuring a reliable operation within rigorous safety standards. The operational range is effective from 0.2 meters up to 9 meters, making it a flexible component in safety applications.
