"Found the part we needed at the best price. Spoke to Rob to make sure the part was actually in stock, as many companies don't actually have the part available to ship. It was in stock ready and the part was checked and shipped and received within a couple of days from their German stock. Would definitely use again and recommend."
The Sick WTB2S-2P3251 is a compact and versatile photoelectric sensor designed for a wide range of automation and industrial applications. This miniature sensor is part of the W2S-2 series and is known for its reliability and high performance in detecting objects with precision.
Featuring a supply voltage range of 10 V DC to 30 V DC, the WTB2S-2P3251 ensures compatibility with various power systems, making it a flexible choice for integration into existing setups. The sensor's PNP switching output and the option to switch between light and dark operation modes allow for easy adaptation to different operational requirements.
With a quick response time of less than 0.5 milliseconds and a switching frequency of 1000 Hz, this sensor is capable of handling high-speed processes with ease. The robust ABS/PC plastic housing and PMMA optics material, combined with an IP67 protection rating, ensure that the WTB2S-2P3251 can withstand harsh industrial environments and a wide range of temperatures from -25 °C to +50 °C during operation.
The sensor's compact dimensions, featuring a small light spot size, make it particularly suitable for detecting small objects and precise positioning tasks. Additionally, the inclusion of protective circuits against polarity reversal, overcurrent, and short circuits provides an extra layer of safety and durability for the device.
With its miniature size, quick response, and reliable detection capabilities, the Sick WTB2S-2P3251 photoelectric sensor is an excellent choice for manufacturers and engineers looking to enhance the efficiency and accuracy of their automation processes.
