Mongoose MPRSWB-S Wireless Rear Parking Sensor Kit with In-Cabin Speaker - Black

Mongoose MPRSWB-S Wireless Rear Parking Sensor Kit with In-Cabin Speaker - Black

A complete wireless rear parking sensor kit with in-cabin audible speaker alarm, delivering accurate 0.30 to 2.60 metre reverse obstacle detection for cars, 4WDs, utes, and commercial vehicles with automatic reverse activation and no cabin cable runs required.

Product Overview

The Mongoose MPRSWB-S is a wireless rear parking sensor kit designed for drivers who want reliable reverse obstacle detection with a simple audible alert and a clean, straightforward installation. Using a 2.4GHz wireless connection between the rear sensor ECU module and the in-cabin speaker, the MPRSWB-S eliminates the need to run cables from the rear bumper through the vehicle's body to the cabin, significantly reducing installation time and labour cost.

The kit includes four 22mm matt black ultrasonic sensors with IP67 rated waterproof cables and connectors, a waterproof and high temperature resistant rear ECU module suitable for external mounting, and a wireless in-cabin speaker unit. The system activates automatically when reverse gear is selected and detects obstacles from 0.30 metres to 2.60 metres. The minimum detection distance can be adjusted to avoid false alerts from spare tyres, tow bars, pedals, and licence plate holders. The wide 10-30V DC operating voltage makes the MPRSWB-S compatible with both 12V passenger vehicles and 24V commercial vehicles and trucks. For metal bumpers, the optional SRS-01 or SRS-02 rubber sleeve rings are available separately, and for trucks or flat metal bumpers, the optional SBT-01 bracket is also available separately.

Features & Benefits

2.4GHz Wireless Speaker Connection: The wireless connection between the rear sensor ECU module and the in-cabin speaker eliminates the need to route cables from the rear of the vehicle to the cabin, reducing installation complexity and labour time while delivering a clean and professional result.

Automatic Reverse Gear Activation: The MPRSWB-S activates automatically when reverse gear is selected, ensuring the parking sensor system is always active when reversing without requiring any manual switching by the driver.

Adjustable Detection to Avoid False Triggers: The minimum detection distance can be individually set to prevent false alerts from spare tyres, tow bars, pedals, and licence plate holders, allowing the system to be fine-tuned for the specific rear configuration of each vehicle.

In-Cabin Speaker with Audible Alarm: The wireless in-cabin speaker provides clear audible proximity alerts, offering a simple and unobtrusive alert solution without requiring a dedicated display screen or dashboard mounting position.

4 x IP67 Waterproof Ultrasonic Sensors: The four 22mm 58KHz ultrasonic sensors feature IP67 rated waterproof cables and connectors, and are water and heat resistant for long-term reliability installed in external rear bumper positions exposed to weather and road conditions.

Paintable Matt Black Sensors: The 22mm matt black sensors can be painted to match the colour of your vehicle's bumper, allowing for a discreet and factory-style integration into the rear bumper without visible contrast.

Wide Voltage Compatibility - 12V and 24V: The 10-30V DC operating voltage makes the MPRSWB-S suitable for standard 12V passenger vehicles, 4WDs, and utes as well as 24V commercial vehicles, trucks, and heavy equipment without any voltage conversion required.

Waterproof and High Temperature Resistant ECU: The rear ECU module is designed for external mounting with IP67 waterproof and high temperature resistant construction, rated for operating temperatures from -40 degrees C to +80 degrees C.

Frequently Asked Questions

What is the difference between the MPRSWB-S and the MPRSWB-D?

Both kits are wireless rear parking sensor systems with the same 4 sensor configuration, detection range, automatic reverse activation, and 2.4GHz wireless connection. The key difference is the alert method. The MPRSWB-S uses an in-cabin speaker for audible alerts only, while the MPRSWB-D includes a colourful LCD display with both visual and audible alerts and a built-in GPS module. Choose the MPRSWB-S for a simpler, more discreet installation, or the MPRSWB-D if you prefer a visual proximity readout.

Does the MPRSWB-S activate automatically when reversing?

Yes. The MPRSWB-S activates automatically when reverse gear is selected, so the system is always ready when you need it without any manual input required from the driver.

How do I prevent false alerts from my tow bar or spare tyre?

The MPRSWB-S allows you to adjust the minimum detection distance for each sensor. By setting the minimum distance appropriately for your vehicle's rear configuration, you can prevent the sensors from triggering false alerts from fixed objects such as spare tyres, tow bars, pedals, and licence plate holders that sit within the sensor detection zone.

Does the MPRSWB-S work with metal bumpers?

The MPRSWB-S is designed for installation in plastic bumpers as standard. For metal bumpers, the optional Mongoose SRS-01 or SRS-02 rubber sleeve rings are required and must be purchased separately. For trucks or vehicles requiring an undermount installation, the optional SBT-01 sensor and ECU bracket is also available separately. Contact us to add these accessories to your order.

Is the MPRSWB-S compatible with 24V commercial vehicles?

Yes. The MPRSWB-S operates on a wide voltage range of 10-30V DC, making it fully compatible with both 12V passenger vehicles and 24V commercial vehicles, trucks, and heavy equipment without any voltage conversion required.
