• Reflector: MS Series

• Retroreflective tape: MST Series

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

- Feature data

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

interference.

• Retroreflective type: If the sensing target has a glossy surface or high reflection, tilt

the sensing target with an angle from 30 to 45 degrees and install the sensor.

Tilt angle

• For installation, tighten the screw with a torque of 0.8 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.

■ NPN open collector output

OCP

SCP

• 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.

STEP Status

Description

Turn the adjuster from MIN to MAX sensitivity and

Received

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

Interrupted

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.
