Wabco 4411015371 Distance Sensor Module

Description

The Wabco 4411015371 Distance Sensor Module is a critical component within air brake systems, specifically functioning as an air valve actuator. It's designed for use in heavy-duty vehicles and trailers to accurately detect distances and provide feedback for precise brake control. This inductive sensor features a 28mm actuating and measuring range, and operates at 12V with a rated current of 100mA. Its radial version and bayonet DIN 72585 A1-2.1-Ag/K2 electrical connection ensure reliable performance in demanding conditions, while its IP6K6K protection class safeguards against dust and water ingress. The sensor's dimensions are 40 x 40 x 365 mm, and it's engineered to OE specification for optimal compatibility and durability, with an operating temperature range of -40°C to +130°C.

Key Features & Benefits

This little guy essentially measures the distance between parts – specifically, it’s usually monitoring the brake shoes and the brake drums or rotors. It sends a signal based on that distance, telling the system how worn your brake components are. It’s an electronic signal, so it’s pretty precise. Newer systems use this to give you an early warning before things get dangerously thin, but it can also work with older setups to just indicate when service is needed. Think of it as an early warning system for your brakes. It's part of the overall air brake system, letting the control module know if the brake pads or shoes are wearing down. It doesn't do the braking, it just reports information. It’s often used in conjunction with automatic slack adjusters, working together to maintain proper brake travel.

Symptoms, Risks & Replacements

It’s important because worn brakes are a serious safety issue. If you don’t catch it early, you risk damaging other components, like the drums or rotors, and obviously, reducing your stopping power. You’ll notice if the sensor isn’t working correctly because you might get a warning light on your dash, or more subtly, the brakes might not feel as strong as they used to. It acts like a shield, giving you time to address wear before it becomes a bigger, more expensive, and dangerous problem. You can find these pretty easily; Fixparts Online carries a good selection of them, and they’re usually a straightforward replacement.
