The V5FF-TQ-3535 Window Fiber Optic Sensor is a medium-size window-type fiber optic head designed for reliable detection of objects passing through a 35 × 35 mm sensing area. It is typically paired with a fiber amplifier, making it suitable for part counting, packaging, and presence detection on conveyors and chutes.
 
Description
V5FF-TQ-3535 uses a through-beam optical path integrated into a rectangular window frame, so any object entering the 35 mm × 35 mm aperture interrupts the light beam and is detected. This configuration provides stable triggering for medium-sized packages or components, even at higher line speeds.
 
Key features
Sensing window size: 89 × 52 × 10.7 mm overall head size with a 35 × 35 mm active window, giving a compact footprint and generous opening for product flow.
Detection distance: 35–35 mm (window depth), optimized for consistent detection across the full opening.
Minimum detectable object: 20 × 20 mm, suitable for medium cartons, pouches, or parts.
Fiber cable: Approx. 2 m length with about 2.2 mm outer diameter, allowing flexible routing to the amplifier.
Typical materials and environment: Stainless-steel/PVC style construction with IP67-grade sealing and compliance with CE and RoHS in this product family, supporting use in harsh industrial environments.
This model is a good fit where you need a mid-size window sensor for counting or presence detection without the bulk of larger 80–120 mm window heads.
