Description
Product Overview
Model 20508011 speed sensor is equipped with an extended protective wiring harness, suitable for long-distance installation requirements of large engine blocks. The sensing head captures the signal from the crankshaft ring and transmits the speed and phase data to the electronic control unit, precisely controlling the fuel injection timing and quantity. The original vehicle sensor wiring harness may age and crack, the sensing probe may fail, and the plug may get waterlogged, causing signal loss and power interruption. The entire wiring sensor assembly can be directly replaced without the need for separate wiring processing. It is suitable for heavy-duty trucks, large excavators, and maintenance and replacement of generator sets.
Unique Core Features of the Single Product
Full-length corrugated protective wiring harness, resistant to wear and bending
The entire wiring cable is wrapped with a spiral rubber corrugated tube, which isolates the friction of engine pipes and high-temperature baking, and is not prone to cracking or breaking when repeatedly bent for a long time, preventing corrosion of the internal copper wire by mud and oil, and extending the lifespan of the wiring harness.
Single-hole brass bushing fixed base, stable installation without loosening
The sensing head is an integrated single-ear installation seat, with an embedded brass metal bushing. The bolt locking is not prone to slippage, and the sensor will not shift under long-term high-intensity vibration, ensuring stable signal collection without drift.
Double-sealed waterproof snap-on plugs at both ends, eliminating wiring faults
Both the sensing side and the host side adopt closed plastic snap-on connectors. The internal multi-layer waterproof and dust-proof rubber rings prevent oxidation and short-circuiting of the pins in rainy construction sites or engine compartment oil immersion environments. The continuous transmission of speed signals is stable.
Split long-wire integrated pre-installation, no wiring required for installation
The sensor probe and wiring harness are fully pre-installed and formed, eliminating the need for on-site stripping, connection, and assembly. Installation and replacement can be directly plugged and unplugged, significantly reducing equipment downtime and maintenance time, and reducing the risk of wiring errors causing faults.
Highly sensitive magnetic response probe, anti-electromagnetic interference
The front-end high-precision sensing magnetic head shields the electromagnetic interference of engine lines. The signal is continuous and without loss in the high and low speed range, avoiding sudden loss of fuel supply and torque limit during heavy-load driving. Applicable scenarios
Suitable for heavy-duty freight trucks, large mining excavators, heavy-duty loaders, high-power stationary diesel generators, and equipment used for 24-hour continuous full-load, high-temperature, and high-dust heavy-duty operations in mining areas and construction sites.
