Ideal for professional applications requiring reliable, adaptable, and maintenance-free liquid monitoring. ## Description ## Features - The intelligent non-contact liquid level sensor uses advanced signal processing technology and high-speed signal processing chip to break through the influence of the wall thickness of the container and realize the true non-contact detection of the liquid level in the closed container. - The liquid level sensor has intelligent liquid level reference adjustment and liquid level memory function, liquid level status display mode, which can realize multi-point series connection; can support high and low level output, NPN, PNP signal output and RS485 communication interface output ;Open collector output mode, wide voltage range (5~24V), suitable for connecting various circuits and product applications(Please Choose the appropriate model for your usage). - High stability, high sensitivity, strong interference capability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference, to be compatible with all 5~24V power adapters on the market. - Strong compatibility, through a variety of non-metallic containers, such as plastic, glass, ceramics and other containers, the sensing distance can reach 20mm; liquid, powder, particles can be detected. - Open collector output mode, wide voltage range (5~24V), suitable for connecting various circuits and product applications. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Taidacent | | Manufacturer | Taida Century Technology | | Country of Origin | USA | | Model number | Y25-1904 | | Item Weight | 45 g | | Package Dimensions | 15.24 x 10.16 x 1.27 cm; 45 g | | Item model number | Y25-1904 | | Are batteries included? | No | ## Images ![Taidacent Non-Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Liquid Induction Level Switch Water Level Switch (NPN Output(24V)) - Image 1](https://m.media-amazon.com/images/I/51KBAfgVsTL.jpg) ![Taidacent Non-Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Liquid Induction Level Switch Water Level Switch (NPN Output(24V)) - Image 2](https://m.media-amazon.com/images/I/61L2M0fnSoL.jpg) ![Taidacent Non-Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Liquid Induction Level Switch Water Level Switch (NPN Output(24V)) - Image 3](https://m.media-amazon.com/images/I/71U2J9O0nmL.jpg) ![Taidacent Non-Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Liquid Induction Level Switch Water Level Switch (NPN Output(24V)) - Image 4](https://m.media-amazon.com/images/I/51QVj5EpG2L.jpg) ![Taidacent Non-Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Liquid Induction Level Switch Water Level Switch (NPN Output(24V)) - Image 5](https://m.media-amazon.com/images/I/511FxsYDbiL.jpg) ## Available Options This product comes in different **Style Name** options. ## Questions & Answers **Q: I see 4 to 5 wires. Can you just power and the sensor will turn off(or on) power when liquid is no longer detected.** A: It's an active sensor, so power must be applied to the power wire all the time for the output to activate. For a passive switch, you might consider something like a float switch that completes a circuit when the float goes up due to water.

I need to trigger an alarm when the water level comes lower than the sensor.** A: Or you can drive directly your filing pump control. **Q: Is there a version of this that works for metal containers ?** A: yes, PLS refer the following type https://www.amazon.com/dp/B07Z66RJWF?ref=myi_title_dp&th=1 **Q: will this work on the outside of 1/2" (13mm) OD silicone tubing ?** A: I guess so : i’am using a 20mm silicone tube and it works fine. It also works when my finger get close to it : close from your 13mm diameter. ## Frequently Bought Together - Taidacent Non-Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Liquid Induction Level Switch Water Level Switch (NPN Output(24V)) - Taidacent Non Contact Water Level Sensor Flow Sensor Float Switch Water Level Switch High and Low Level Output - Taidacent Non Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Pipe Water Float Switch NPN Output Capacitive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/644459027-taidacent-non-contact-liquid-level-sensor-contactless-water-level-sensor](https://www.desertcart.co.uk/products/644459027-taidacent-non-contact-liquid-level-sensor-contactless-water-level-sensor) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
