Basic Information

Introducing the new standard in CMOS laser displacement sensors

Features

This single instrument delivers both high-precision measurement and computer-driven data analysis

High resolution of 0.5 μm 0.020 mil

Thanks to high-precision measurement at a resolution of 0.5 μm 0.020 mil and an LED digital display that provides exceptional ease of use, the HL-G1 series will see use in a variety of applications on production lines worldwide.

Quick

Setup is fast and efficient by using the built-in digital display to set measurement parameters such as sampling cycle and output options.

Compact

The HL-G1 series features a compact design despite its built-in controller and digital readout. Thanks to our miniaturization technology, it can easily be installed on robot arms and in confined spaces.

Friendly

The HL-G1 series now features a userfriendly interface that offers improved ease of use when operating via computer software or HMI unit for more sophisticated operation and analysis.

Easy input settings while looking at digital display

The built-in digital display makes it easy to perform sensor setting while checking displacement values.

Lightweight body that can be installed on movable parts

Its lightweight resin body weighs 70 g approx., which can be installed on moving parts such as sliders and robot arms. Cable with superior flexibility is fitted as standard.

Compact

Compact size despite the built-in controller and digital read out.

Easy to embed in machines and production lines

Controller installation and mounting space is not required because controller function is included in sensor unit.

IP67 protective enclosure protects from water and dust

Thanks to its IP67 protective enclosure, the HL-G1 can be used in the presence of water and dust.
Mounting holes are lined with metal sleeves, allowing the instrument to be tightened securely in place with up to 0.8 N·m of torque.

Timing input and multi input

In addition to timing input select the desired input according to your application:

•Zero set on / off
•Laser control
•Reset
•Teaching
•Memory switching
•Saving

Featuring 3 outputs and an analog 2 outputs

With three outputs, the HL-G1 can be used to generate HI / GO / LOW judgment output or alarm output. The analog output can be used in both current and voltage modes.

Support for both NPN and PNP polarity [GLOBAL SUPPORT]

A single model number accommodates both NPN and PNP wiring polarity, reducing the number of model numbers that must be registered for maintenance purposes.

Featuring 3 outputs and an analog 2 outputs

With three outputs, the HL-G1 can be used to generate HI / GO / LOW judgment output or alarm output. The analog output can be used in both current and voltage modes.

Memory switching function

Up to four groups of sensor settings can be stored for fast recall. Easy switching among setting groups allows smooth setup changes.

HIGH FUNCTION TYPE (HL-G1□-S-J / HL-G1□-RS-J)

The integrated communications interface lets the sensor communicate with upstream devices such as PLCs.

Sensors and other devices can be connected in a 1:1 manner using RS-422, or up to 16 HL-G1 series sensors can be connected using RS-485, enabling them to return measured values in response to messages from the PLC.
When using one of our PLCs*, you can use the PLC’s data write / read instructions (F145 and F146) to easily configure HL-G1 series settings and acquire measurement output.
* Supported PLCs from Panasonic Industry: FP0R, FPΣ, FP-X

Software tool for sensor configuration and evaluation (Free download available)

In addition to configuring up to 16 sensors at once, this free tool makes it easy to gather data needed for analysis, such as received light waveform monitoring and data buffering. The interface language can be selected at the time of installation.

● Data buffering
Stores and displays measurement data, which can be superimposed on previously recorded data for easy comparison and analysis.
● Received light waveform display
Displays the amount of light received by cell from lightreceiving element.
● Measured value display
