SICK WTB2S-2N1330 Photoelectric sensor
SICK WTB2S-2N1330 miniature diffuse photoelectric sensor, NPN, part 1064578. Tiny W2S housing for small-part detection in tight machine spaces.
Overview
The SICK WTB2S-2N1330 (part number 1064578) is a miniature diffuse photoelectric sensor from the W2S micro housing family with NPN output. Its small footprint is aimed at machines where every millimeter counts, such as electronics assembly equipment, compact handling systems and tight conveyor sections.
How It Works
The sensor projects modulated light and detects the portion reflected by the object. When the received light passes the sensitivity threshold, the output switches. As with all energetic diffuse sensors, the achievable range depends on target color, surface and size, and the sensitivity control adapts the unit to the task.
Key Features
- Miniature W2S housing for extremely tight installation spaces
- NPN switching output (N order code)
- Adjustable sensitivity for light and dark targets
- Precise light spot for small-object detection
- Modulated light for stable operation near lighting and displays
- Lightweight housing suitable for moving tooling
Typical Applications
- Small-part detection on electronics assembly machines
- Presence checks in compact feeder and pick-and-place systems
- Detection of components in narrow guide channels
- Monitoring of micro conveyors and transfer units
- Verification of insert presence in small fixtures

Installation and Setup Notes
Because the housing is tiny, plan the cable exit and strain relief during machine design rather than as an afterthought. Set sensitivity with the real target, and expect shorter range on dark objects. Clean the small optical face regularly, as even light soiling affects a miniature sensor faster than a larger one.
Frequently Asked Questions
How small is the WTB2S housing?
The W2S family is one of the smallest rectangular photoelectric formats, intended for mounting where larger sensors cannot fit.
Which output does this variant provide?
An NPN switching output; PNP variants are available for other control schemes.
Can it detect shiny metal pins?
Yes, though the angle matters for shiny parts; test orientation so the reflection returns to the receiver.
