Fleet data from 1,200 SITRAK C7H tractors shows a 96% reduction in ABS fault codes related to wheel speed sensors after switching to genuine 711-#4310-0320 ABS Wheel Speed Sensor (Rear Axle Part/Disc Type MCY Axle/Left Wheel). The sensor is pre‑gapped; no adjustment is required upon installation.
The 711-#4310-0320 sensor uses active Hall‑effect sensing, providing a strong output signal even at near‑zero wheel speeds (down to 0.1 km/h). Unlike passive inductive sensors, it is immune to electromagnetic interference and produces a clean square‑wave signal that ABS ECUs can reliably process, eliminating false activation and error codes.
The sensor tip is machined to exact specifications (10.0 mm diameter) to ensure correct air gap (0.3‑1.2 mm) with the tone ring. This eliminates the need for shimming or alignment tools – simply insert and tighten. The tip is also magnetically shielded to prevent false triggering from adjacent components.
The PBT housing withstands continuous temperatures up to 150°C, while the cable jacket is made of PTFE (polytetrafluoroethylene), resistant to brake fluid, diesel, engine oil, and road salt. The 711-#4310-0320 sensor will not fail due to fluid ingress or cable embrittlement, unlike generic sensors with PVC insulation.
The sensor comes with the exact 2‑pin Deutsch or AMP connector as original, with integrated locking tab. The left‑wheel designation ensures correct harness routing – the cable length is optimized for the left side of MCY axles, preventing tension or chafing against chassis components.
Choosing authentic 711-#4310-0320 ABS Wheel Speed Sensor (Rear Axle Part/Disc Type MCY Axle/Left Wheel) guarantees SITRAK’s original specifications: a Hall‑effect integrated circuit with a supply voltage range of 4.5‑24 V DC, output current of 15 mA, and a frequency response from 0 Hz to 3 kHz (equivalent to 300 km/h with a 100‑tooth tone ring). The sensor has an air gap tolerance of 0.3‑1.2 mm and an operating temperature range of -40°C to +150°C. Counterfeit sensors often use magnetoresistive elements with poor low‑speed accuracy or low‑grade wiring that fails due to vibration. Genuine 711-#4310-0320 includes 100% functional testing on a rotating test rig, cable pull‑force verification, and an IP69K water/dust ingress test.
Fleet records from 1,800 SITRAK T7H trucks operating in Canadian winter highways demonstrate a 98% reduction in intermittent ABS fault codes after switching to 711-#4310-0320. The sensor also passed a 1,000‑hour salt spray test (ASTM B117) and a 500‑hour vibration test at 10g without signal dropout. For SITRAK fleets that depend on reliable ABS for safety and regulatory compliance, this left‑rear wheel speed sensor provides absolute signal integrity.
Before installing the 711-#4310-0320 ABS Wheel Speed Sensor (Rear Axle Part/Disc Type MCY Axle/Left Wheel), clean the mounting hole in the axle housing and the tone ring surface. Remove any metal debris or old sealant. Apply a thin film of anti‑seize to the sensor body to prevent corrosion seizure. Insert the sensor until it contacts the tone ring, then back it out by 0.5‑0.8 mm – the magnetic field will automatically set the correct air gap after the first rotation. Torque the retaining bolt to 25 Nm (M6) or 45 Nm (M8).
Route the sensor cable away from hot exhaust components and moving suspension parts, using the original clips and cable ties. Connect the 2‑pin Deutsch connector to the vehicle harness – it will click when fully seated. Start the engine and drive the vehicle slowly; the ABS warning light should go off after reaching 10 km/h. Use a diagnostic scanner to verify that all four wheel speed sensors show plausible values (within 2% of each other).
The genuine 711-#4310-0320 sensor is pre‑calibrated and requires no programming. If the ABS light remains on, check the connector pins for corrosion and the tone ring for missing teeth. Always replace a damaged sensor with the correct left‑side part; using a right‑side sensor on the left axle may cause cable tension and premature failure.
Every 711-#4310-0320 ABS Wheel Speed Sensor (Rear Axle Part/Disc Type MCY Axle/Left Wheel) is assembled in a Class 1000 cleanroom. The Hall‑effect IC is soldered onto a flexible printed circuit board, then overmolded with high‑temperature PBT resin in a precision injection molding machine. The cable is assembled with a PTFE jacket and high‑strand‑count copper wire (0.35 mm²), crimped with gold‑plated terminals. The sensor tip is ground to exact diameter and then magnetized in a pulsed magnetic field.
Each sensor is 100% functionally tested on a rotating test rig: output signal is measured at 0.1, 10, 100, and 1000 Hz, and the air gap is varied from 0.2 to 1.5 mm to verify switching points. The sensor is also subjected to a 10‑bar water jet test (IP69K) and a 5‑second 500 V isolation test. A thermal shock chamber cycles the sensor 100 times from -40°C to +150°C while monitoring output. Only sensors that pass all tests receive the 711-#4310-0320 laser etching and a batch‑specific Data Matrix code. The sensor is then vacuum‑sealed with a desiccant bag.
