Precautions
Refer to the Technical Information section for general precautions.
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.
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 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 F capacitor between the 0 V terminal and the frame.
J APERTURES
Four kinds of reticles are included with the sensor as follows: (A) (B) (C) (D) 0.5 mm by 3 mm, horizontal slit 1 mm by 3 mm, horizontal slit 3 mm by 0.5 mm, vertical slit 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. Excessive forces (hitting by hammer, or the like) should not be applied to the product because they may damage its water-resistance ability.
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. Attach the selected reticles on the lens of the light source head and receiver head respectively.
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.
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.
NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4.
