Inductive Clamp

NEW! Inductive Clamp for Engine RPM channel

This inductive clamp includes a built-in signal conditioning circuit specially designed to be used on ignition-coil 12 volt wires. This clamp is specially useful on cars and with on-spark coils (which do not have a high voltage clamp).

Specs

• Type of sensor: inductive (preferably used on the coil’s 12V wire, only one wire at a time)
• MEDIUM size (previous was 15 cm, current is 10 cm)
• Input: 5-12V (March 2026 model, < 20 ma). *
• Output: 0-5V pulses according to ignition sparks (1:1)
• Polarity: it is sensitive to the direction of current, the user may need to test both directions of the clamp until he gets a better signal

Note: SP1s between 2017 and 2022 have 12V Output!. Current units (March 2026) already include a 5V LDO regulator to be able to operate from 5V to 12V. If you have an previous model clamp which is contact with us to find a solution (resistors, replacing the PCB, etc)
