Precautions
Refer to the Technical Information section for general
precautions.
For extending the sensor wires, use a cable greater than AWG
22 in diameter and shorter than 100 m. As impedance of the
extended cable increases, the supply voltage applied to the
sensor terminal will decrease, and the low level output voltage at
the cable end will increase. For this reason, consider the voltage
fluctuation when extending the sensor cable.
J OPTICAL AXIS ADJUSTMENT
Move the light source head and the receiver vertically and
horizontally to obtain a proper angular range in which the
operation indicator turns ON. Then fix both of the heads securely.
J POWER SOURCE
When using a commercially available switching regulator, be sure
to ground the FG (Frame Ground) and G (Ground) terminals;
otherwise, faulty operation of the sensor may be caused by the
switching noise.
J MOUNTING
The main body and both heads must be fitted to a warping-free
mount using the attached screws with a torque of 5.5 kg • cm or
below.
J EFFECT OF ELECTRICAL NOISE
The sensor output may be affected by noise from switching
regulators or the other instruments. In this case, place a 0.47 µF
capacitor between the 0 V terminal and the frame.
J APERTURES
Four kinds of reticles are included with the sensor as follows:
(A) 0.5 mm by 3 mm, horizontal slit
(B) 1 mm by 3 mm, horizontal slit
(C) 3 mm by 0.5 mm, vertical slit
(D) 3 mm by 1 mm, vertical slit
J MATERIALS OF SENSOR HOUSING
The main body and the heads are made of ABS resin. The lens
sections of the both heads are made of acrylic resin. They may
be dissolved by organic solvent and strong acidic substances.
Use the reticles when the detected surface of object is smaller
than 2 mm in width, or when mutual interference must be
reduced. Select a pair of reticles the same size according to the
above conditions.
Excessive forces (hitting by hammer, or the like) should not be
applied to the product because they may damage its
water-resistance ability.
Attach the selected reticles on the lens of the light source head
and receiver head respectively.
J WATER RESISTANCE
The photomicrosensor does not have a complete water-resistant
construction. The water-resistant level of the product is IP64
(IEC529). Therefore, do not use or store it in water or in rainfall.
J CONNECTIONS
Routing the wire of the photomicrosensor in close proximity to
high potential power lines may result in malfunction or damage
because of inductive effects. Be sure to route the sensor wires
separate from the power lines or through a separate conduit.
NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4.
