Application:
The 2874A008 / CH12003 crankshaft speed sensor is engineered for
Perkins 1104C-E44T, 1104D-E44T, 1106D-E66TA and 1206E-E70TTA
turbocharged four- and six-cylinder diesels, and is directly
retro-fittable to the 4.236, T4.236 and AT4.236 turbocharged 4.0 L
engines. These power units are widely used across Massey Ferguson
5400, 6400 and 7400 Series agricultural tractors, combine
harvesters, 40–250 kVA generator sets, tele-handlers, wheel loaders
and industrial sweepers. In these applications the sensor bolts
through the flywheel housing and measures the rotational speed of
the 118-tooth crankshaft ring gear, delivering a digital
square-wave or analogue sinusoidal signal to the engine control
unit. This real-time data is essential for precise fuel injection
timing, automatic idle control, governor regulation and
diagnostics, ensuring reliable cold starts and optimum performance
under varying load and ambient conditions.
Technical specifications:
The unit is a Hall-effect / variable-reluctance two-wire sensor
with M12 × 1.5 male thread and 19 mm hex, 50 mm overall length and
90 g net weight. It operates from 8–30 V DC, draws <15 mA and
delivers a 0–5 V square-wave or 0–100 V peak-to-peak sinusoidal
signal whose frequency is proportional to engine rpm.
Material & performance features:
The body is machined from 1.4571 (AISI 316Ti) stainless steel for
superior corrosion resistance in marine, agricultural and
high-humidity environments. The sensing element is encapsulated in
high-temperature epoxy resin achieving IP67 ingress protection, and
the assembly withstands 1 000 h salt-spray exposure per ASTM B117.
