Product Overview
SICK WT2S-P231 (part number 1022659) is a sub-miniature photoelectric proximity sensor with background suppression designed for precise object detection in tight automation layouts. Operating on 10 to 30 V DC, it uses a focused red PinPoint LED emitter and optical triangulation to detect targets between 1 mm and 30 mm while ignoring reflective backgrounds. The compact housing features dual brass-reinforced mounting sleeves and an integrated pigtail cable for direct panel or arm mounting.
Key Features
- Detection principle: Optical proximity with background suppression (BGS)
- Sensing range: 1 mm to 30 mm
- Light source: PinPoint visible red LED (660 nm)
- Operating voltage: 10 V DC to 30 V DC
- Output configuration: PNP, light-switching (light-ON)
- Switching frequency: 800 Hz with response time under 0.6 ms
- Enclosure rating: IP67 and IP69K rated for washdown environments
- Housing dimensions: 7.6 mm wide by 25.1 mm tall by 12.5 mm deep
- Mounting: Dual brass-reinforced M2 through-holes
Applications
- Detects small electronic components or IC leads on high-speed surface-mount feeder tracks.
- Monitors component pocket presence or small vial positioning in automated packaging machinery.
- Mounts onto end-of-arm tooling in pick-and-place robotics where head weight and envelope space are restricted.
- Serves makers and robotics builders configuring precision non-contact boundary sensing or miniature part sorters.
Frequently Asked Questions
What output type does the WT2S-P231 use?
This sensor provides a PNP transistor output configured for light-switching (light-ON) operation, sourcing up to 50 mA.
How is the sensor mounted?
The housing includes two integrated brass-sleeved mounting holes designed for M2 machine screws, preventing housing compression during installation.
What is included with this sensor?
Listing includes the used SICK WT2S-P231 sensor with integrated wire pigtail. Mounting hardware and mating connectors are not included.
When clearance inside an automated cell comes down to millimeters, sub-miniature sensing keeps your line running without eating up physical space.
