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 e x t e n d e d c a b l e i n c r e a s e s , th e s u p p l y v o l t a g e a p p l i e d to th e sensor terminal will decrease, and the l ow level output voltage at the cable end will increase. For this reason, consider the voltage f l u c t u a t i o n wh e n e x t e n d i n g t h e s e n s o r c a b l e .
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 i ncl uded with the s ensor as follows: (A) (B) (C) (D) 0. 5 m m b y 3 m m , h o r i z o n t a l s l i t 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 m ain body and the heads are m ade of ABS resin. The l ens sections of the both heads are m ade of acrylic resin. They may be dissolved by organic s olvent and s t r o n g a c i d i c s u b s t a n c e s . 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 c onditions. Attach the selected reticles on the lens of the light source head and receiver head respectively.
J CONNECTIONS
Routing the wire of the photomic r o s e n s o r i n c l o s e pr o x i m i t y t o 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 s eparate c onduit.
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.
