Fork sensors (also called slot sensors) use through-beam photoelectric technology to detect objects passing through the slot. The rugged one-piece housing, available in U- and L-frame styles, keeps the emitter and receiver in alignment, and includes a convenient, single-cable connection.

Fork Sensors
Fork sensors, also called slot sensors, are U- and L-shaped through-beam object detecting sensors that have the transmitter and receiver built into the opposing "fork" arms of the sensor housing. They offer several advantages over standard through-beam sensors in certain applications:
- Identical mechanical and optical axis
- Operational reliability and repeatability
- Transmitter / receiver built into the same housing
- Models available for clear object and liquid detection
- Ease of installation - one connection point

U-Frame
U-frame fork sensors are designed for easy installation and feature a rugged one-piece, metal construction to assure constant alignment. These versatile sensors offer high resolution, sensitivity adjustment, and selectable light-on/dark-on operation.
- AutomationDirect and di-soric brands
- Fork openings from 5 to 250mm
- Visible red, infrared, and laser light options
- Rugged aluminum, die-cast zinc, or stainless steel housings
- IO-Link v1.1 on select models
- 10 to 30 VDC operating voltage
- Up to 14kHz switching frequency
- PSTI series liquid detection models in 30 or 80mm sensing distances
- A clear object detection model with an 80mm sensing range (PSTL-0P-6F)
- PSUFR series harsh duty sensors in 50 or 80mm sensing distances
- PSUL series laser light models to detect small objects
- M8 or M12 quick-disconnect options
- Up to IP69K protection ratings

(PSUR-0P-1F)
L-Frame
AutomationDirect L-frame photoelectric fork sensors offer mounting flexibility due to their angled design. This is helpful in situations where space is limited, or the sensors need to be positioned at an angle for better object detection.
- Fork openings from 60 to 160mm
- Visible red and infrared light options
- Rugged die-cast zinc housings
- 10 to 30 VDC operating voltage
- Up to 2kHz switching frequency
- Adjustable sensitivity
- Selectable light-on/dark-on operation
- 3-pin M8 quick-disconnect
- IP67 protection rating
