Parker Meggitt 111-912-000-011 TQ912 Proximity Sensor
The base ordering identity for a reverse-mount TQ912 eddy-current proximity sensor, completed by configuration codes for environment, thread, cable and chain length.
Product Profile
111-912-000-011 is the base ordering identity shown for the TQ912 reverse-mount proximity sensor. A complete order includes additional option codes that define the finished sensor configuration.
TQ912 shares the TQ9xx eddy-current measurement principle but differs mechanically from the standard-mount TQ902. The reverse-mount form must be confirmed from the installation drawing.
Available ordering decisions include standard or Ex environment, metric or imperial body thread, integral-cable length, optional cable protection and total system length.

System Role
Forms the sensing front end of a calibrated TQ9xx proximity measurement chain.
Provides reverse-mount access where the installation geometry requires it.
Works with the selected cable arrangement and IQS900 signal conditioner.
Supports shaft vibration, gap or position measurement when the complete chain is configured correctly.
Compatibility
- Treat the bare ordering base as incomplete for procurement; provide every configuration suffix.
- Do not exchange reverse-mount and standard-mount bodies without mechanical review.
- Keep total system length consistent across sensor and extension cable.
- Match Ex coding across every component used in a hazardous-area measurement chain.
Applications
- Reverse-mount proximity sensing on rotating-machinery shafts.
- Gap and axial-position channels in approved machinery-monitoring systems.
- Replacement of a TQ912 configuration whose complete suffix is available.
FAQ
Q01Is 111-912-000-011 a complete ordering number?+
It is the documented TQ912 ordering base. Environment, thread, cable, protection and total-system-length option codes are required to define the finished sensor.
Q02Can 111-912-000-011 replace a TQ902 sensor?+
Not automatically. TQ912 is reverse-mount and TQ902 is standard-mount, so installation geometry and the full chain configuration must be checked.
Q03What should accompany a 111-912-000-011 quotation?+
Provide the full suffix string, thread, cable length, optional protection, total system length, Ex requirement, EA902 cable and IQS900 configuration.
Q04How is total system length controlled for 111-912-000-011?+
It is the sum of the sensor integral cable and any EA902 extension cable. Use only an approved combination for the selected 1 m, 5 m or 10 m chain.
Q05What must be tested after installing 111-912-000-011?+
Verify reverse-mount clearance, target gap, connector and cable integrity, signal scaling, diagnostics and the applicable machinery-protection function.
