Anti-lock Brake System (ABS) Sensors

Technology such as anti-lock brakes (ABS) and electronic stability are now common place thanks to the ABS sensor or wheel speed sensor. A small device, it has a big role to play; monitoring the wheel’s speed and rotation to prevent the brakes from locking. So, it’s important to always fit an OE quality part - anything less could compromise the effectiveness of these safety critical systems. Featuring weather pack connectors and plated pins, and rigorously tested to OE standards, Delphi ABS sensors deliver optimum signal stability and reliability in all conditions, for an accurate, long-lasting sensor that you can fit with confidence.

Latest OE technology

Our ever-expanding range of ABS sensors features the latest digital signal technology. By creating a digital, square wave, Delphi magneto resistive and hall effect sensors only change frequency, not amplitude, improving accuracy, especially at lower speeds. They can also detect the direction of the wheels; forward, reverse and even stop. This is vital for hill hold control, autohold and automatic parking assistance technologies.

Protection from the elements

Given its position, the ABS sensor is particularly vulnerable to contamination from dirt and moisture. That’s why Delphi ABS sensors feature weather-pack connectors that lock out dirt, moisture, chemicals and other contaminants, coupled with plated pins for even great corrosion protection and improved conductivity.

Extreme testing

Water, heat and vibration can all affect a sensors characteristic. So we subject all our sensors to extensive thermal, shock and vibration testing just to be sure. With test temperatures ranging from -40 o C to 140 o C, we know they’ll perform even in the most challenging conditions. Delivering optimum stability and reliability at all times.

Easy installation

For right-fist-time fitment, Delphi ABS sensors are designed to match the OE. With like-for-like mounting and connector designs and wire lengths, technicians can fit quickly and easily, straight from the box.

The complete solution

As well as a growing range of ABS sensors, we also offer advanced diagnostic capability including the ability to read live fault codes and individual wheel speed data, essential repair data through our vehicle technical information package, and expert training and technical support.

Resource Highlights

Braking in conventional vehicles and electric vehicles are two almost completely different concepts. To perform effective repairs and maintenance, it’s worth learning some of the key differences between EV braking and conventional vehicle brakes.

Learn how regenerative braking works, and some of the key differences to conventional vehicles, with this video guide from the experts at Delphi. We’ll take you through some of the big talking points including:

How does regenerative braking work?
What happens when the brake pedal is pressed in EVs
The bedding-in process for brake pads

Do EV brakes last longer?

Yes, electric vehicle brakes tend to last longer than their conventional counterparts. It’s the electric motor within EVs that does most of the work on slowing the vehicle down, which means there’s less wear and tear on EV brakes.

Do all EVs have regenerative braking?

Any vehicle with an electric motor – that applies to both EVs and hybrid vehicles – has the ability to perform regenerative braking. That means recycling power back into the vehicle and slightly extending its time until needing a charge.
On the latest vehicles, the front RaDAR shares information with the EV motor controller to adjust the amount of regeneration dynamically, depending on what is on the road ahead.

How much range does regenerative braking add?

How much energy can be recovered through regenerative braking depends on a number of things such as battery charge, battery temperature, and driver settings. It depends on the customer’s driving style, but tests have shown that you can recover up to 20% of the energy,which is then used to extend the range.

What is single pedal driving?

Single pedal or one-pedal driving applies to electric vehicles, where drivers can bring the vehicle to a complete stop without using the brake pedal. It takes some practice to get it right when there are things like stopping distances to take into account, but it saves wear and tear on the brake pads.
