Wabco 1835230004 Sensor 90x20x20mm

Description

This Wabco 1835230004 sensor is a critical component within trailer brake control systems, specifically for air brake applications. It plays a vital role in ensuring the safe and efficient operation of air brakes on trailers. This sensor is manufactured to OE specification, guaranteeing reliable performance and compatibility. Its dimensions are 90 x 20 x 20 mm, allowing for a compact and precise fit within the system. The sensor’s design enhances system responsiveness and contributes to improved braking performance and overall vehicle safety.

Key Features & Benefits

This sensor essentially reads wheel speed. It’s a magnetic speed sensor, so as the wheel turns, it picks up the rotation and sends that information as an electrical signal to your trailer’s brake controller. It’s a pretty simple concept, really – it just counts how fast things are spinning. It's a key piece of the anti – lock braking system, specifically for trailers with electric brakes. The brake controller uses the signals from all the wheel sensors to figure out if a wheel is slowing down faster than the others – indicating a potential skid. If it detects that, it momentarily releases the brake on that wheel, helping to keep the trailer stable and preventing a lock – up. It’s part of what keeps everything under control, especially when you’re hauling a load or driving in less – than – ideal conditions.

Symptoms, Risks & Replacements

If this sensor fails, you’ll likely notice if you're towing. The trailer's braking might become uneven, or the ABS light on your tow vehicle might come on. Worse case scenario, you could lose braking power to a wheel, leading to instability and a serious safety hazard. It's one of those parts that acts like a shield, preventing bigger problems. It's a relatively inexpensive part, honestly, and you can find them easily enough – we carry them here at Fixparts Online, and a lot of other places do too. But a failure can quickly become a costly, and dangerous, situation. It’s always best to address it right away.
