CAUTIONS

Make sure that the power supply is off while wiring. Take care that wrong wiring will damage the sensor.

Verify that the supply voltage variation is with-

in the rating. If power is supplied from a commercial

switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. In case noise generating equipment (switching

regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. Do not run the wires together with high-voltage

lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

Do not use during the initial transient time

(50ms) after the power supply is switched on.

Extension up to total 50m is possible with a

0.3mm Make sure that stress by forcible bend or pulling

is not applied directly to the sensor cable joint. Take care that the sensor does not come in direct

contact with organic solvents, such as, thinner, etc. Make sure that the sensing end is not cov-

ered with metal dust, scrap or spatter. It will result in malfunction. Do not rub the surface of the spatter-resistant

type sensor with a hard object. It will wear out the fluorine resin coating.

3) (e.g.) The pigtailed type of GX-12MLUB is 'GX-12MLUB-J'. The maximum operation distance stands for the maximum distance for which the sensor can detect the

4) standard sensing object. The stable sensing range stands for the sensing range for which the sensor can stably detect the standard sensing object even if there is an ambient temperature drift and/or supply voltage fluctuation. It is the leakage current when the output is in the OFF state.

5) The maximum load current varies depending on the ambient temperature. Refer to ' CONNECTION'.

6) When the cable is extended, the residual voltage becomes larger.

7) The weight of the spatter-resistant type is as follows.

Conditions for the load

The load should not be actuated by the leakage current (0.8mA) in the OFF state. The load should be actuated by (supply voltage - 3V) in the ON state. The current in the ON state should be between 3 to 70mA DC.

In case the current is less than 3mA, connect a bleeder resistance in parallel to the load so that a current of 3mA, or more, flows.

to mate the connectors. Holding the fixing ring of the sensor side connector, turn the fixing ring of the cable side connector clockwise till it stops.

Note: Tighten the fixing ring completely to make the

connection fully waterproof.

Removal

Turn the fixing ring counterclockwise and, holding the fixing ring, pull to separate the connectors.

Notes: 1)

Use the mating cables as shown below. CN-24-C2 (Oil, heat and cold resistant cable, 4-core, 2m, Do not use it near a welding place.) CN-24-C5 (Oil, heat and cold resistant cable, 4-core, 5m, Do not use it near a welding place.)
