Precautions for Correct Use Handling of Fiber Cable • When mounting the Switch to a panel, be sure to use the toothed lock washer attached as an accessory (to M5, M8, and M16 types • Do not pull or impose any force exceeding 29.42 N on the fiber only). Use the washer on the panel surface opposite the object to cable. be detected by the Switch. • Make sure that the bending radius of the fiber cable is as large as possible and at least R20 mm.

Connection of Contact Output • Do not impose compressing loads on the fiber cable. Load Fiber cable 12 VDC 10 mA Nylon clip D5A Load 24 VAC 10 mA D5A Consideration of polarity is not required. Connection of Solid-state Output • The fiber cable can be cut with OMRON’s E39-F4 Cutting Tool. • Be sure to connect the load to the power source in series. • Do not impose any force exceeding 29.42 N on the cable, otherwise • The operating state of the Switch can be checked by the LED the cord may break. Make sure that the bending radius of the cable operation indicator (lights when the Switch is in operation) is at least 20 mm. incorporated in the solid-state output circuit. Mounting • The output residual voltage is approximately 3 V. Therefore, exercise care when selecting the load and setting the supply • The screw sections of cases for M5, M8, and M16 types have voltage. The residual voltage, however, can be easily calculated special dimensions. Do not use the mounting dimensions specified because it is almost constant and is free from the influence of for standard types. fluctuation in the load current. • For the mounting dimensions, refer to the following figures and tables. 100 mA max.

Since the must operate voltage of the relay is 80% or less than the (Toothed lock washer) rated voltage, it is 12 × 0.8 = 9.6 V. The supply voltage, in turn, is 3 + 9.6 = 12.6 V. Therefore, the relay may not operate with a 12 V power source. (2) However, if the relay rated at 24 VDC is employed, the must operate voltage Type Slim Limit and supply voltage of the relay are respectively 19.2 V and 22.2 V.

Blue (Black) Blue (Black) • However, they can be connected in parallel provided that both Dog switches A and B in the above figure do not operate at the same Dog time and that the load does not have to be kept energized. In this circuit, however, the leakage current is increased, multiplied by the Stopper number of Switches connected in parallel. Consequently, the Switch may not release properly. To keep the load energized, Stopper connect a relay to each of the Switches as shown below. • Attach an appropriate cover for the protection of the D5A from machining oil or cuttings. No protective cover is, however, provided together with the Switch. Brown Brown Load • Exercise care that excessive force is not applied to the ceramic (White) (White) plunger of M5, M8, or slim type. If the possibility exists that strong shock may be applied to the plunger when the Switch is being mounted, use a protective cap. Blue Blue The plunger may not release if it is depressed with too great a force. (Black) (Black) Set its stroke by referring to the OT value indicated in Operating Characteristics. Connection to Power Source M5, M8 Slim • Be sure to connect the Switch to the power source via the load. If directly connected to the power source, the internal elements of the Switch may be damaged. Brown (White) Blue (Black) • Do not mount the Switch with its nameplate facing downwards (i.e., in the direction of gravity), otherwise the oil drain hole will not work effectively. • Correctly connect the white and black lead wires to the positive and negative sides, respectively, of the power source. Although the Oil drain hole D5A will not be damaged even if the polarity is reversed by mistake, Switch if this happens, the Switch maintains the ON state (i.e., the contact is kept open) regardless of the presence or absence of the object to be detected.
