Product Description
WTB2S-2P3251 SICK Pressure Temperature Transmitter -40 To 185°F 100-240VAC
WTB2S-2P3251 Description
The WTB2S-2P3251 is an ultra-compact, rectangular photoelectric proximity sensor with background suppression (BGS) technology, engineered for reliable detection of small, dark, or reflective objects in confined industrial spaces. It uses a high-precision PinPoint red LED light source (640 nm) to deliver a focused, stable detection beam, with adjustable sensing range from 1 mm to 150 mm (standard operating range 18–110 mm). Equipped with PNP switching output, light/dark selectable mode, and IP67 protection, it ensures consistent performance in harsh industrial environments, ideal for precise presence, positioning, and counting tasks.
WTB2S-2P3251 Key Features
- Ultra-compact rectangular housing (7.7 × 27.5 × 13.5 mm) for installation in extremely limited spaces
- Advanced background suppression (BGS) eliminates interference from background surfaces, ensuring accurate detection of target objects only
- PinPoint red LED (640 nm) with Ø3.5 mm focused light spot (at 50 mm) for reliable detection of small parts and low-reflectivity objects
- 3-turn precision potentiometer for easy, fine adjustment of sensing distance
- PNP transistor output with light/dark switching selectable, max 50 mA output current
- Fast response time (<0.5 ms) and high switching frequency (1,000 Hz) for high-speed automation lines
- IP67 environmental protection, dustproof and waterproof, suitable for wet and dusty industrial conditions
- Wide 10–30 V DC supply voltage range with reverse polarity and short-circuit protection
- Long-life LED (100,000 hours average service life) for minimal maintenance
