F&C Slotted/fork-type Photoelectric Sensor FC-SPX304P

The FC-SPX304P is a slotted or fork-type photoelectric sensor manufactured by F&C Sensing Technology. It is a through-beam sensor, the emitter and receiver are in a single "fork" unit, and it detects objects that break the infrared light beam passing between them. The "P" in the model name signifies that it has a PNP (Positive-Negative-Positive) output.

Key specifications

• Sensor type: Slot/Fork-type through-beam photoelectric sensor.
• Manufacturer: F&C Sensing Technology.
• Detection distance: The standard detection distance is 5mm, which refers to the width of the slot.
• Output type: PNP (Positive-Negative-Positive) with both normally open (NO) and normally closed (NC) options.
• Detection object: Opaque objects, as small as 2 x 0.8mm, can be detected.
• Operating voltage: 5–24 VDC ±10%.
• Response time: 0.3ms max.
• Load current: 100mA max.
• Light source: 940nm infrared modulated light.
• Connection: The standard model comes with a 2-meter, 4-wire cable.
• Environmental protection: Rated IP64 for protection against dust and splashing water.
• Features: Includes protection against reverse power polarity and short circuits.

Common applications

The FC-SPX304P is designed for use in industrial automation for reliable position detection and limit protection. Its small slot size makes it suitable for tasks such as:

• Positioning
• Counting
• Absence or presence detection
• Mark detection
• Liquid level detection
