What is the sensing range of the SF-2 sensor?

The SF-2 series has a measuring range of 100-1000 mm (10cm to 1 meter), making it ideal for short-range distance measurement and object detection in industrial equipment, production lines, and warehouse management systems.

Is the SF-2 suitable for AGV and robot applications?

Yes. The SF-2's small blind zone (0-80mm), fast response time (195ms), and compact surface-mount design make it ideal for AGV obstacle avoidance and robot positioning. The battery power support (4.2-5.5 V DC) is particularly beneficial for mobile robotic platforms.

What output types are available?

The SF-2 provides three output types: 1 PNP switching output for simple on/off control, 1 analog output (voltage or current) for continuous distance data, and 1 digital output (RS232/485 or TTL) for advanced communication.

Can it be used in harsh environments?

Yes, the sensor features IP68 protection and uses ABS housing. It operates in temperatures from -40°C to 70°C, making it suitable for outdoor and harsh industrial environments.

What does the blue LED indicate?

The blue LED indicates that the power is on. The yellow LED flashes when a program function object is detected, and the red LED indicates an error or object not detected status.
