Small aluminium fork sensor 10 by 45 by 57 mm with M8 connector

Sick

Sick WF15-40B410 Fork Sensor 15 mm 0.2 mm MDO

SKU CH-PGZH-A5ZPT

Fork sensor with 15 mm width detects 0.2 mm objects using infrared LED and selectable NPN/PNP output

  • Detects objects as small as 0.2 mm with 15 mm fork width
  • Infrared LED optical principle ensures reliable label detection
  • Selectable light/dark switching via plus/minus button teach-in
  • IP65 aluminum housing resists dust and water ingress
  • 10-30 V DC supply with 100 mA PNP/NPN output current

Industrial Optical Fork Sensor

The Sick WF15-40B410 is a fork-shaped optical sensor designed for precise object detection in industrial automation. It uses an infrared LED light source to identify items as small as 0.2 mm across a 15 mm fork width. The unit offers selectable NPN or PNP output with light/dark switching via a teach-in button.

Replaces Basic Photoelectric Sensors

This sensor upgrades from standard through-beam or diffuse sensors when consistent label or edge detection is required. The fixed 15 mm fork width and 42 mm depth eliminate alignment between separate emitter and receiver units. The jump is worth it for high-speed web handling or packaging lines needing reliable 0.2 mm minimum detectable object performance.

Mounts Directly On Machinery

The aluminium housing measures 10 mm x 45 mm x 57 mm and connects via a 4-pin M8 male connector. It operates on 10 V DC to 30 V DC supply voltage with IP65 enclosure rating for dust and water resistance. Short-circuit and reverse polarity protection safeguard the output. The 100 ms initialization time allows rapid system startup.
