Fiber Optic Analog: SA1C-FK
Key features:
• High-speed, miniature photoelectric sensors with
analog (4 - 20mA) and digital output
• Senses gradual color changes
• Available in red or green LEDs
• Through-beam and reflected-light sensing available
• Ideal for either color mark applications or simple
presence and absence applications requiring analog
output
• Compact size allows for DIN rail mounting
• Fiber optic units available to address specific applica-
tion needs
• Simple to install
• IP66 protection rating
Built on the foundation of SA1C-F, SA1C-FK is ideal for either color mark applications or simple presence
and absence applications requiring analog output.
Featuring analog and digital output, this sensor comes in through-beam or reflected-light sensing styles.

1. Analog current output specification is based on the power voltage range from 12 to 24V DC (±10%).
Use the attached resistor (249Ω, 1/4W) as a load resistance for converting analog output to voltage.
2. Response time for analog current output is between 10% and 90% of the rise or fall of the voltage signal when using a 249Ω resistor.
