Rigid PIPEHarness™ - Gas Engine Ignition CAL, CAC, & CMB

Rigid PIPEHarness™ - Gas Engine Ignition CAL, CAC, & CMB

Our PIPEHarness™ systems, first patented in 1972, set the global industry standard for robustness. CMR provides gas and dual fuel engine ignition wiring solutions for engines and gensets in industrial and marine markets.

gas engine ignition pipe harness
Operating Temperature Range
Min -50°C / Max 85°C (100 hours at 125°C)
Electrical Connection
• Internal wiring is designed according to each application. For thermocouples, it can be either common negative or wire to wire. A PT 100 sensor can be installed for the cold junction temperature compensation
• Each base is wired to the main male connector with high temperature PVC insulated cable
• The pipe is fitted with dispensed polyurethane, for perfect insulation, sealing and vibration protection
• Electrical connections can be customer specific or standard JAEGER connectors. For NATO application the connectors are from SOURIAU or JUPITER
Usually 3.2 Kg/meter
Up to 6 metres
Usually 60x60mm, 30x30mm, 50x50mm
Other Dimensions
Up to 90mm x 90mm
IP54 or 64
Other Features
• The pipes can be considered as mechanical parts offering the corresponding savings, allowing sensors with identical extension cord lengths
• Mounted with one bracket, approximately every 1.5 metres


Your ability to perform is based on a need for absolute reliability.

Enclosed within aluminium profiles, using typical 60mm x 60mm extrusions, the CMR PIPEHarness™ protects your critical wiring on the engine platform and internally, within the crank case.

Typical applications of the Gas Engine Ignition PIPEHarness™ range includes:
• Transmission of power supply for ignition coils
• Connection of sensors used for monitoring gas and dual fuel engines
• Transmission of measuring signals

Main benefits include:
• Installation of ignition coils (gas engines) and pulse transmission.
• A concept mix : ignition pipe + “classical” PipeHarness™ (CMR patent)
• Pipes carrying high voltage for supplying ignition coils and low-level signal (measurement)
• Simplified engine cabling
• Reduced costs of cabling
• Installation and replacement of sensors in minimum time
• Impossibility of inversion when connecting sensor
• Standardization of sensors (cable length) and optimization of spare parts stocks
• Pipes allow for the transmission of all low-voltage and low-level signals.
• Fool-proof and pre-wired system, designed to reduce wiring operations on the engine. No special installation skill required (plug and play)
• The pipe is fitted only with 2 or 3 brackets

All CMR PIPEHarness™ products are produced using automated cut, strip and termination, build board assembly with best in class test systems support by Cirris test software.
