• Bracket B

• M12 connector cable: C□D(H)4-□-□

Cautions during Installation

• Be sure to install this product by following the usage environment, location, and specified

ratings. Consider the listed conditions below.

- Installation environment and background (reflected light)

- Sensing distance and sensing target

- Direction of target's movement

- Characteristic curves

• When installing multiple sensors closely, it may result in malfunction due to mutual

interference.

• For installation, tighten the screw with a torque of 0.5 N m. Mount the brackets correctly to

prevent the twisting of the sensor's optical axis.

• Do not impact with a hard object or bend the cable excessively. That could decrease the

product's water resistance.

• Use this product after the test. Check whether the indicator works appropriately for the

positions of the detectable object.

Through-beam

Emitter - Receiver:

Install to face each other

Timer Setting

• In case of the built-in timer model, you can set the OFF Delay timer.

(adjustable time: 0.1 to 2 sec)

• Use the offered adjustment screwdriver. Do NOT turn with excessive force to prevent product

damage.

• T: Setting time by the adjuster (setting time: 0.1 to 2 sec)

• t: ≤ 3 ms (When the adjuster is set to Min (0.1 sec))

• If the interrupted time (Ta) after receiving the light is shorter than the setting time (T),

the transistor output maintains the ON state.

• OCP (over current protection), SCP (short circuit protection)

• If short-circuit the control output terminal or supply current over the rated specification, normal control signal is

not output due to the protection circuit.

Sensitivity Adjustment

• Set the adjuster for stable Light ON area, minimizing the effect of the installation environment.

• Use the offered adjustment screwdriver. Do NOT turn with excessive force to prevent

product damage.

• The steps below are based on Light ON mode.

Turn the adjuster from MIN to MAX sensitivity and

check the position (A) where the operation indicator

activates under the light ON area.

Turn the adjuster from (A) to MAX and check the

position (B) where the operation indicator activates

under the light OFF area.

If the operation indicator does NOT activate at the

MAX (maximum sensitivity): MAX = (B).

Set the adjuster at the mid position between (A) and

(B) for optimal sensitivity.
