CX-20 Product is discontinued Successor CX400 SERIES Amplifier Built-in Compact Photoelectric Sensor General Purpose Photoelectric Sensor with Full Basic Performance Marked Conforming to EMC Directive Compact Size Two Sensors Mountable Together Waterproof Just 20mm in depth, 5mm shorter than a conventional model. CX-29 (retroreflective type), CX-22 and CX-24 (diffuse reflective type) incorporate an automatic interference prevention function. Hence, two sensors can be mounted close together. The sensor can be hosed down because of its IP67 construction and the non-corrosive stainless steel mounting bracket. 5mm shorter CX-23, CX-28 or CX-28IR ( CX-21, ) do not have this function. 20mm 31mm 12mm Note: However, take care that if it is exposed to water splashes during operation, it may detect a water drop itself. Strong Light Beam Insusceptible to Extraneous Light: CX-23 Plug-in Connector Type Is Available CX-21 (thru-beam type) emits a strong light beam which can pass through 20 sheets of copier paper. The sensor incorporates an infrared LED that is strong against dust or dirt. As the spread of the beam from the CX-23 emitter is narrow, close mounting of sensors is possible. Plug-in connector type sensor, which can be easily disconnected for replacement, is available. In case a problem occurs anyone can replace the sensor in a minute.

Its use is not intended or designed to protect life and prevent body injury or property damage from dangerous parts of machinery. It is a normal object detection sensor. Mounting • The tightening torque should be 0.5Nm or less. M3 (length 12mm) screw with washers MS-CX2-1 (Optional) 03/2003 Operation mode switch D L Light-ON mode is obtained when the switch is turned fully counterclockwise. D L Dark-ON mode is obtained when the switch is turned fully clockwise. Others • Do not use during the initial transient time (50ms) after the power supply is switched on. • When connecting the mating cable to the plug-in connector type sensor, the tightening torque should be 0.4Nm or less. 39 CX-20 PRECAUTIONS FOR PROPER USE Retroreflective type sensor with polarizing filters • If a shiny object is covered or wrapped with a transparent film, such as those described below, the retroreflective type sensor with polarizing filters may not be able to detect it. In that case, follow the steps given below. Example of sensing objects • Can wrapped by clear film • Aluminum sheet covered by plastic film • Gold or silver color (glossy) label or wrapping paper Retroreflective type sensor for sensing transparent objects • Optimum sensing is possible when the position of the transparent sensing object is set at the center of the sensor and the reflector. If the sensing position is set near the sensor or the reflector, the sensing may be unstable. In this case, set the sensing position at the center of the sensor and the reflector. Steps • Tilt the sensor with respect to the sensing object while fitting. • Reduce the sensitivity. • Increase the distance between the sensor and the sensing object. Self-diagnosis function (Self-diagnosis output type only) • The sensor diagnoses the incident light intensity, and if it is reduced due to dirt or dust, or beam misalignment, an output is generated. Insufficient beam intensity Insufficient beam interruption Stable light received level Sensing output threshold level Stable dark level Sensing condition Sensing output (operation indicator) (in the Light-ON mode) Sensor Reflector Transparent sensing object • When the sensor detects an uneven plastic receptacle or glass bin, the received light intensity may differ with the sensing position or direction. Adjust the sensitivity after confirming the stable sensing condition by turning the sensing object, etc. • If the object is a transparent cylinder, feed it in a position as shown in Figure A. The sensor may fail to detect an object fed in a position as shown in Figure B. ON (Lights up) OFF (Lights off) Lights up Stability indicator Self-diagnosis output Lights off 2 1 1 3 ON OFF Reflector 1 The self-diagnosis output transistor stays in the ‘OFF’ state during stable sensing. 2 When the sensing output changes, if the incident light intensity does not reach the stable light received level or the stable dark level, the selfdiagnosis output becomes ON. Further, the self-diagnosis output changes state when the sensing output changes from Light to Dark state. (It is not affected by the operation mode switch.) 3 In case of insufficient beam interruption, there will be a time lag before the self-diagnosis output turns ON.
