Pro-Range XKC-Y26A-PNP Non-Contact Liquid Level Sensor - DC 24V PNP Output

The XKC-Y26A-PNP provides a standard PNP (sourcing) transistor output signal. This output is compatible with the digital input modules of most Programmable Logic Controllers (PLCs), relays, and industrial controllers that accept a 24V DC switching signal, making integration straightforward.

This sensor is designed for non-contact detection through the walls of non-metallic containers, such as those made from plastic, glass, or certain composites. It cannot reliably detect liquid through metallic walls due to electromagnetic shielding effects. The container material and wall thickness may affect sensitivity, which is adjustable on the sensor.

The sensor is specified for a 24V DC operating voltage. Applying a voltage outside this rating, such as 12V or 5V, may result in unreliable operation or damage to the sensor. For systems with different logic levels, an appropriate external power supply or signal conditioning circuit is required to provide the correct 24V DC power.

Yes, its primary advantage is non-contact through-wall detection, which makes it ideal for monitoring corrosive, toxic, or otherwise hazardous liquids like acids and solvents. Since the sensor does not contact the fluid, there is no risk of chemical attack on the sensing element, ensuring long-term reliability and safety.
