Polypropylene Vertical Float Switch, Normally Open, 250V AC

The PLS‑031A‑6PPI is a compact magnetic power level sensor engineered for dependable liquid‑level monitoring in demanding industrial and mains‑voltage environments. Operating with a reliable Form A (normally open) reed contact, it provides stable switching performance across a diverse range of fluid‑handling systems. Its robust construction, featuring a durable polypropylene housing and a lightweight PP‑foam float, ensures long‑term reliability. The materials are FDA‑tested, offering excellent chemical resistance and making the switch suitable for applications requiring hygienic or food‑safe components, such as in beverage or pharmaceutical processing.

With a broad operating‑temperature range from -20°C to +80°C, this float switch performs consistently in challenging conditions. Its robust electrical characteristics, including a 250V AC switching voltage and a 1.5A switching current, make it a versatile choice for control circuits. The sensor is designed for vertical installation and is ideal for integration into pumps, tanks, domestic appliances, and general process‑control applications where precise liquid level detection is critical. Its compact dimensions allow for installation in space‑constrained locations without sacrificing performance.
