Specifications
SWIFT 40 Transducer Performance
P
ARAMETER SPECIFICATION
Use
SWIFT 40 A (aluminum) for
SWIFT 40 T (titanium) for
low weight, high sensitivity
high fatigue life, durability
Maximum usable rpm
2,200
Maximum speed
240 kph (150 mph)
fits rim size (usable range)

*
* A special flange configuration is required for a 13 inch wheel. Larger diameter rims can be used, providing
that overall clearance from brake calipers and suspension components is maintained.

170.5 mm (6.713 in)
Input voltage required
10–17 VDC
Input power required per transducer
30 W maximum (22 W typical)
Output voltage ± full scale calibrated load
±10 V
Load impedance >1 kΩ; 0.01 µF (maximum) load capacitance.
SAE J328 rated load capacity
Aluminum Titanium
12 kN (2,700 lbf) 22.7 kN (5,100 lbf)
