SICK WTF12-3P2431 Photoelectric Proximity Sensor
Product Introduction
The SICK WTF12-3P2431 is a robust photoelectric proximity sensor
from the W12-3 series, designed for reliable object detection in
diverse industrial environments. Featuring a foreground suppression
function and a visible red LED light source, it excels in
recognizing objects regardless of surface color or reflectivity.
Housed in a rugged cast metal body with IP67 protection, it
withstands harsh conditions such as dust, moisture, and mechanical
stress, making it suitable for packaging, pharmaceuticals, food and
beverage, and other demanding industries.
Features
Foreground Suppression Technology: Ensures accurate detection of
foreground objects while ignoring background interference, making
it ideal for applications with varying surface colors (e.g., black,
gray, white targets with 6%, 18%, 90% reflectivity).
High Performance: Equipped with PinPoint technology, which delivers
a bright, small, and precise light spot for easy alignment. Boasts
a fast response time (≤330 µs) and high switching frequency (1,500
Hz) for detecting fast-moving objects.
Rugged Construction: Cast metal housing (rectangular design, 15.6mm
x 48.5mm x 42mm) with IP67 protection rating resists dust, water,
and mechanical impact, ensuring durability in industrial settings.
Comprehensive Protection: Includes short-circuit and reverse
polarity protection to safeguard against electrical faults,
enhancing operational safety.
User-Friendly Design: Integrated green (power) and yellow (light
reception) LED indicators for real-time status monitoring; a
potentiometer allows easy adjustment of the sensing range (30mm to
175mm).
Versatile Integration: Supports 10-30V DC power supply, PNP
switching output (max. 100mA), and IO-Link compatibility for
convenient data access to programmable logic controllers (PLCs).
