OEX Alternator 12V 150A Denso Style DXA4011

The OEX Alternator DXA4011 is a new 12V alternator with a 150A power rating, built in a Denso style layout for applications that require a 5 groove pulley and internal regulator. It is supplied as an each unit and is fitted with a clutch style pulley, so matching the pulley arrangement and mounting style is important before ordering.

Key physical details include a pad alternator mount, an 8mm adjusting hole diameter, an 8.5mm pivot hole diameter, and a 55mm pulley outside diameter. The unit weighs 5.94kg and uses pin code IR135, which gives you several useful points to compare against the existing alternator before fitting.

OEX describes this alternator as a product sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO9001 certified factories. It is backed by a 3yr Passenger / 1yr Commercial warranty, which is useful context if you are choosing a replacement for a daily-driven vehicle or a commercial application.

This alternator is listed as Denso suit unit make and falls under rotating electrical components. As with any charging system part, the safest approach is to confirm the part number DXA4011, the 12V specification, the 150A output, and the pulley and mount details against the vehicle before purchase.

Application and Buying Notes

Before ordering, compare the existing alternator against DXA4011, especially the 12V rating, 150A output, IR135 pin code, 5 groove pulley, and pad mount arrangement. Those details are the most useful checks when replacing a charging system component, because alternators can look similar while differing in regulator, pulley, and mount configuration.

The fitted clutch style pulley is another point to verify carefully. If the vehicle currently uses a different pulley arrangement, the alternator may not be a direct match even when the make and voltage appear close. Measuring the pulley outside diameter at 55mm and checking the 8mm adjusting hole and 8.5mm pivot hole can help confirm the physical match.

If you are replacing an existing Denso style alternator, this unit is designed to suit that type of application and is listed with Denso as the unit make. That said, the best confirmation is always the part number and the vehicle application details together, rather than relying on appearance alone.

The 150A output is a useful specification for vehicles with higher electrical demand, but it should still be matched to the original charging system requirement. Fitting a higher or lower output alternator without confirming the vehicle’s original setup can lead to compatibility issues, so check the existing unit label, mounting points, and plug identification before purchase.

For Volvo applications, the supplied fitment preview includes S40 and V50 references, with S40 coverage shown across multiple model years from 2004 to 2012 and V50 coverage shown from 2004 in the preview. Use that as a starting point only, then confirm the exact application against the vehicle and the current alternator hardware before fitting.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXA4011 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA4011, Brand OEX, Description OEX Alternator 12V 150A Denso Style, Adjusting Hole Diameter 8, Pivot Hole Diameter 8.5, Pulley Outside Diameter 55mm, Regulator Type Internal, Voltage 12, Alternator Mount Pad.

OEX Alternator 12V 150A Denso Style. Part number DXA4011 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4011, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number DXA4011, 12V system voltage, 150A output, IR135 pin code, 5 groove pulley, clutch style pulley, pad mount, and the vehicle application details before ordering.
