▲ The sensing head is as small as 2.8mm;

▲ Not limited by installation location and installation space;

The detection distance is more than twice that of traditional proximity sensors, with a maximum detection distance of up to 7mm.

Component Name


Usage Guide

Cylindrical type

Fix the sensing head with screws at a distance of 5mm or more from the tip of the sensing head (locking torque: maximum 2N · m).

Please fasten GX-402 on metal parts that are 15mm or less away from the tip.

Threaded type

When installing the threaded sensing head, do not tighten it with a torque greater than the one shown in the table below.

connection

Connect the sensing head and amplifier with a high-frequency coaxial line. The extension length is limited to 10m (5m for GX-302 and GX-402).

Environmental Metals
Embedded sensors can be directly installed inside metal bases, while non embedded sensors must be installed according to the instructions in the table to reduce interference caused by metal environments.


interfere

(1) Anti interference operation mode switch setting

Do not set the anti-interference operation mode switch of two adjacent GN-A1 to the same mode,

As shown in the following figure:

(2) Sensor head

When installing two or more sensors of the same model face-to-face or in parallel, they should be isolated according to the distance listed in the table below to avoid interference.

Note:

The data shown in the table above is when the regulator is adjusted to the stable detection position. Within parentheses

The value is the data obtained when using an anti-interference converter in parallel with the sensing head.

Connection of sensing head

1. Modify the front end of the sensor cable. And confirm that the buried wire and wire core are twisted tightly separately.
*When the coating is peeled off, the buried wire is wrapped around the wire core. Before modifying the sensor wire, the buried wire and wire core should be separated first.

2. Loosen the fastening screws of the wiring board counterclockwise.

3. Insert the sensor directly into the insertion interface of the amplifier, and confirm that the buried wire and wire core are inserted into the correct interface, and that the sensor wire is not twisted.

4. Tighten the fastening screws of the terminal block clockwise, with a tightening torque not exceeding 0.15N · m.

5. Start the amplifier and confirm that the unconnected alarm output is in the OFF state. If the indicator light is ON, you must return to step 1 and repeat the operation.

adjustment

Both NEAR-ON and NEAR-OFF modes can be applied

The NEAR-ON mode uses a normally open relay that closes when a target object is detected. The NEAR-OFF mode uses a normally closed relay that opens when a target object is detected.

NEAR-ON operation

When positioning the target object, rotate the adjuster clockwise and locate point A where the output indicator light has just turned on. If the output indicator light is on, rotate the regulator counterclockwise.

2. Move away the target object, rotate the adjuster clockwise again and find point B where the output indicator light is on.

NEAR-OFF operation

When positioning the target object, rotate the regulator clockwise and locate point A where the output indicator light is off. If the output indicator light has turned off, rotate the regulator counterclockwise.

2. Move away the target object, rotate the regulator clockwise again and find point B where the output indicator light goes out.

3. Set the regulator to the middle position between point A and point B. Output when the output indicator light is on
