Industrial Laser Displacement Sensor

The Keyence LJ-G030 is a 2D sensor head designed for precise height measurement in industrial environments. It uses a 655 nm laser to capture displacement data with a linearity of ±0.1 % of full scale. The unit operates on a 3.8 ms sampling cycle for consistent trigger intervals.

Suited for Automated Inspection Lines

This sensor suits production lines that require non-contact height profiling within a 0 to 50 °C temperature range. It is not intended for buyers who need integrated controller functions or wireless data transmission. The device also does not support operation in condensing humidity above 85 % RH.

Verify Mounting and Environmental Limits

Confirm that your installation can maintain ambient conditions between 32 and 122 °F with relative humidity from 35 to 85 %. Ensure the mounting geometry accommodates the sensor head form factor without exceeding the specified temperature envelope. Check that your control system can synchronise with the 3.8 ms trigger timing.

Questions about this item

What controller or amplifier unit is required to operate the LJ-G030 sensor head?

The LJ-G030 is a sensor head only and must be connected to a compatible Keyence controller, such as the LJ-G series controller, for power, signal processing, and output.

Can the LJ-G030 operate alongside older Keyence laser sensors on the same production line?

Yes, the LJ-G030 uses a 655 nm wavelength and standard analogue or digital interfaces, allowing integration with existing Keyence controllers and multi-sensor setups without interference.

How can I verify the LJ-G030 is measuring within its specified linearity after installation?

Place a calibrated reference target at the measurement centre distance and confirm the output deviation stays within ±0.1% of full scale across the sampling cycle.
