Purchase now: Wenglor HM24PA2 InoxSens Sensor
Purchase now: Atlantech Drives provides you the Wenglor HM24PA2, a heavy-duty Reflex Sensor with Background Suppression (BGS) belonging to the prestigious InoxSens family. Designed specifically for hygienic applications in the food, beverage, and pharmaceutical industries, this sensor is encased in a high-grade Stainless Steel V4A (1.4404/316L) housing. It is built to withstand high-pressure washdowns, aggressive cleaning agents, and steam cleaning, complying with ECOLAB standards and IP69K protection ratings.
Technical Specifications and Hygienic Design
The HM24PA2 uses visible Red Light to reliably detect objects up to 200 mm away, regardless of their color or background. Its defining feature is the gap-free mounting capability when used with the InoxSens system, which eliminates bacterial traps where dirt could accumulate. The optics are made of scratch-resistant glass (or specialized plastic compliant with FDA), and the laser-welded housing ensures zero ingress of fluids. It features a precise potentiometer for range adjustment, protected by a watertight cap.

Expert Tips: Washdown Procedures
Cleaning is aggressive. Expert Tip: While the HM24PA2 is rated IP69K (100 bar pressure at 80°C), you must ensure the connector is equally robust. Always use PVC-free cables with V4A coupling nuts (like Wenglor’s hygiene cable series). Using a standard nickel-plated brass connector on a stainless sensor in a washdown area will lead to galvanic corrosion and seal failure within weeks.
Frequently Asked Questions (FAQs)
Q: What does «Background Suppression» mean?
A: It means the sensor triangulates the distance. It will detect the target (e.g., a milk carton) but ignore the steel machine part moving just 10mm behind it, avoiding false triggers.
Q: Is it suitable for acids?
A: Yes, V4A stainless steel is highly resistant to industrial acids and alkalis used in CIP (Clean-In-Place) processes.
