User manual OMRON E3JM DATASHEET

[. . . ] 24 to 240 VAC±10%, 50/60 Hz 3 W max. 2 W max. Relay output (M Models): SPDT 250 VAC, 3 A max. DC SSR output (S, R Models):48 VDC, 100 mA max. (residual voltage: 2 V max. ) Light-ON/Dark-ON selectable Mechanical 50, 000, 000 times min. [. . . ] As with the Through-beam Model, adjust the Reflector and Sensor. Since the directional angle of the E3JM Retro-reflective Model is 1 to 5 degrees, pay careful attention when adjusting the Sensor. 12 to 240 VDC 24 to 240 VAC Diffuse-reflective Models The indicator of the Diffuse-reflective Model with the timer function is lit in the same way as for the Through-beam Model. Retro-reflective Models NO COM Tb Tc Receiver NC Ta Sensing object is present. Sensing object is not present. 345 12 Power source E39-R1 Reflector Sensing object (A) Operation (C) Release (B) Operation 12 to 240 VDC 24 to 240 VAC Diffuse-reflective Models NO COM Tb Tc Receiver NC Ta Sensitivity Sensitivity 345 12 Sensing object Power source 12 to 240 VDC 24 to 240 VAC 1. If a sensing object is present as shown above, turn the sensitivity adjuster clockwise to increase the sensitivity. Point (A) is where the indicator is lit. Remove the sensing object and turn the adjuster clockwise. Point (B) is where the indicator is lit by background objects. Turn the adjuster counterclockwise to decrease the sensitivity, starting from the point (B). Point (C) is where the indicator is lit. The center point between the point (A) and point (C) is the optimum position. If the indicator is not lit by the background object at the maximum sensitivity, set to the center point between the point (A) and the maximum sensitivity. Note: The sensitivity adjuster may be damaged if an excessive force is applied. Precautions for Correct Use Switch Configuration Models without Timer Models with Timer MODE 0 1 D·ON L·ON TIMER SW2 Switch for operating mode L·ON SW1 MODE 0 1 D·ON Switch for operating mode Switch for timer mode 6 Multi voltage photoelectric sensor Switch Selection Models without Timer Models with Timer ON-delay MODE 0 1 D·ON L·ON MODE 0 1 D·ON L·ON SW1 TIMER SW2 TIMER SW2 D·ON OFF-delay MODE 0 1 L·ON SW1 One-shot delay MODE 0 1 D·ON TIMER SW2 L·ON SW1 Dark-ON, Transistor output ON MODE 0 1 D·ON L·ON Light-ON, Transistor output ON Both SW1 and SW2 at "0. " Only SW2 at "1. " Only SW1 at "1, " which overrides either setting of SW2. Note: The switch for the operating mode is the same as that for models without a timer. Connecting and Wiring Recommended outer diameter of cables is from 6 to 8 dia. Be sure to firmly tighten the cover in order to maintain waterproof and dustproof properties. Terminal Protection Cover (Accessory) The terminal protection cover is designed to improve safety by maintaining the sensitivity properties of the product and by preventing any contact with charged sections while it is being operated with the mode set to the timer mode. Mount the product as shown in the following diagram (mount the Through-beam Model on the Receiver side). Terminal protection cover Cable End Treatment Adjust the four wires to the same length when the Ta output is to be used only. If both the Ta and Tb outputs are to be used, treat them as shown in the following diagram. Approx. 45 mm Power source Tc, Ta E3JM Approx. 55 mm Rubber bushing (accessory) (See note. ) Washer (accessory) (See note. ) Tightening nut (accessory) (See note. ) Recommended Crimp Terminal Dimensions (Unit: mm) Round type 10 max. (After crimping) 7 max. Output Relay Contact If a load, such as contactor or valve is used that may produce arc when it is turned OFF, the NC (or NO) side may turn ON before the NO (or NC) side is turned OFF. When using both the NC and NO outputs, use an arc killer. Connecting and Wiring DC SSR Output Models When using the DC SSR output model, the total of the load current for the Light-ON output (NO) and that for the Dark-ON (NC) should be 100 mA max.
