The PHR Cam and Crank Hall Effect sensor is designed for builders and tuners needing a more stable and/or reliable sensor for motor speed and sync. A lot of ECU's can use these sensors for getting a cleaner and more consistent reading. This leads to faster starts, fewer tigger faults, more accurate ignition timing as well as several other benefits.

The benefits of using Hall Effect Sensors over VR (Magnetic) sensors is a long list:

• Resistance to Electro Magnetic Interference (EMI)
• Very little or no filtering required
• No minimum engine speed to produce a minimum trigger voltage. Important with a slow cranking motor especially with low battery voltage
• Triggers precisely on trigger edge and not on trigger voltage threshold position in VR's waveform (which can vary with motor speed)
• Easy Cam and Crank Syncing
• Precise Ignition Timing
• No Ignition Timing Float
• Immune to Target Runout
• Rotational Alignment to target is not critical
• High Speed Operation (up to 15khz)

Some benefits specific to the PHR Cam and Crank Hall Effect Sensor Kit are:

• Direct bolt-on
• Brackets made from Billet Aluminum
• Uses DTM Connectors and Terminals
• Large Operating Temperature Range
• Works with all aftermarket ECU's.
• Uses Stock Trigger Wheel and Cam teeth
• Made in the USA
