However, when the background is specular, it may ( be necessary to change the angle of the sensor. ) range (m) EQ-34: Correlation between material () and sensing range (typical) ong Range m The EQ-3 series can detect an m away. It is suitable for various applications, such as, sensing s or positioning s traveling on a wide assembly line, etc. m m nonglossy.m nonglossy (ightness: ) Cardboard Plywood rubber These bars indicate the sensing range with the respective s when the distance adjuster is set at the sensing range of m, m and.m long, each, with white. m Two istances (Far and Near) Can be Set With, two sensing distances, Far (Main) and, can be set. Hence, one sensor can suffice where, earlier, two were required. Compact It saves space, since a miniaturized housing of WH84 has been designed for the fixed-focus sensing sensor even though the adjustable sensing range is m long. Insusceptible to Contamination on ens The fixed-focus sensing keeps the detectability better than diffuse reflective type sensors even if the lens is contaminated by dirt, dust, mist, or smoke under an unclean environment. 4 Far (Main) Near (Sub) 8

Mechanical -turn djuster with Indicator It features a mechanical -turn distance adjuster with an indicator that shows the set distance at a glance. Waterproof It has IP7 protection. It can be used in places splashed with water. djuster indicator istance adjuster (-turn) Note: However, take care that if it is exposed to water splashes during operation, it may detect a water drop itself. Plug-in Connector Type Is vailable Plug-in connector type, which can be easily disconnected for replacement is available. In case a problem occurs, anyone can replace the sensor in a minute. (Excluding ) "4 Plug-in connector type EQ-34-J EQ-34-PN-J M connector (IEC conforming) Mating cable CN-4-C (Cable length: m) CN-4-C (Cable length: m) Principle of Fixed-focus with -segment Photodiode Normal reflective type sensors operate by sensing the variation in the amount of incident beam. However, the fixed-focus reflective sensing type sensor incorporating the -segment photodiode operates by sensing the variation in the incident beam angle. Thus, the output is activated according to the distance of the from the sensor. This system helps the EQ-3 series in being unaffected by color or a background, enabling stable sensing. -segment photodiode Emitting E is based on the difference in the incident beam angle of the dotted line and the solid line in the above figure. 3

PRECUTIONS FOR PROPER USE This product is not a safety sensor. Its use is not intended or designed to protect life and prevent body injury or property damage from dangerous s of machinery. It is a normal detection sensor. Mounting The tightening torque should be.8nm or less. M4 nut M4 (length ) screw with washers Stability indicator Since the EQ-3 series uses a -segment photodiode as its receiving element, and sensing is done based on the difference in the incident beam angle of the reflected beam from the sensing, the output and the operation indicator operate according to the distance. Further, the stability indicator shows the margin of the incident light intensity and not that of the distance. Hence, the distance at which it lights up/off depends on the reflectivity and is not at all related to the output operation. o not use the sensor when the stability indicator is off (unstable light received condition), since the sensing will be unstable. MS-EQ3- (Optional) Care must be taken regarding the sensor mounting direction with respect to the s direction of movement.

Specular face o not make the sensor detect an in this direction because it may cause unstable operation. Others o not use during the initial transient time (ms) after the power supply is switched on. When connecting the mating cable to the plug-in connector type, the tightening torque should be.4nm or less. Tilt If a specular body is present in the background, wrong operation may be caused due to a small change in the angle of the background body. In that case, install the sensor at an inclination and confirm the operation with the actual sensing. Take care that some s may produce a dead zone right in front of the sensor. 8
