JENGOG · JTR M18 SERIES
JTR M18 inductive proximity sensors
For an M18 sensor request, start with the complete existing model and installation. The June 2025 JENGOG catalog lists JTR-18N5DB and JTR-18P5DB as flush-mount, 5 mm, normally-open variants for metal-target detection.

Before choosing a replacement
- Output and logic: compare NPN or PNP, normally open or normally closed, supply and the controller’s input requirements.
- Mechanical fit: confirm the M18 thread, flush mounting and available body length against the catalog dimension drawing.
- Target conditions: send the metal type, target size, gap and nearby metal. A listed 5 mm distance is not a guarantee for every target or mounting arrangement.
- Cable or connector: the named catalog variants have a cable. If replacing a connector model, include a wiring or pinout reference.
An M18 thread and similar sensing-distance number do not establish a drop-in replacement. Pricing and current availability are checked per request.
Supplier documentation
These supplier catalog images show a series reference and dimension example. They are not a customer installation or a verified match to another brand.

Send a complete M18 request
Send the full existing model, quantity and destination country. A nameplate, wiring or installation photo is useful when the suffix is unclear. For a new machine, describe the metal target, actual gap, mounting position and controller input. We can then review the supplier catalog variant and identify what still needs technical confirmation.
Common questions
What differs between JTR-18N5DB and JTR-18P5DB?
The catalog lists the first as NPN normally open and the second as PNP normally open. The controller input must match the selected output.
Is every M18 proximity sensor a 5 mm flush model?
No. The 5 mm flush specification on this page applies only to the named catalog variants. Other M18 models can have different distances and mounting styles.
Can you verify another brand’s M18 replacement from a photo?
A photo helps identify the housing and model. Output, wiring, installation, target and sensing gap also need to be compared before any replacement is proposed.
