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 parts of machinery. It is a normal object detection sensor. Use the sensor head and the amplifier together at a set. Mounting of the sensor head * The tightening torque with M3 screws should be 0.29N m or less. Wiring * If the attached sensor head cables need to be extended, use two single core shielded cables of at least equivalent quality. (Extension up to total 5m is possible.) If a joint terminal or connector is used for extension, refer to the figures below. (The shielded extension cable must be of "1.45mm outer diameter.) Connection with joint terminal Beam- Beamemitting receiving The beam-emitting cable cable cable and the beam-receiving cable should be separated from each other as much as possible. NG Beamemitting cable Beamreceiving cable This distance should be as short as possible. OK Connection with metal connector M Beam- Beamemitting receiving cable cable OK Metal-sheet Double-feed Detection NG The beam-emitting cable and the beam-receiving cable must not be connected to one metal con-nector.

SS-A1 SS-AT1 Wiring * Use a miniature commercially available power-relay terminal base to connect SS-A1 or SS-AT1. Other * Do not use during the initial transient time (50ms) after the power supply is switched on. Suitable terminal base: AP3822K produced by Matsushita Electric Works Co., Ltd. SM2S-05B produced by IDEC IZUMI Co., Ltd. TP514S1 produced by Fuji ELECTRIC Co., Ltd. Timer functions * SS-AT1 and SS-AT9 have three convenient built-in timer functions. ON-delay (OND) <Function>: Neglects short output signals. <Application>: As only long signals are extracted, this function is useful for detecting if a line is clogged, or for sensing only objects taking a long time to travel. OFF-delay (OFD) <Function>: Extends the output signal for a fixed period of time. <Application>: This function is useful if the output signal is so short that the connected device cannot respond. ONE SHOT (OSD) <Function>: Outputs a fixed width signal upon sensing. <Application>: This function is useful when the input specifications of the connected device require a signal of fixed width. Of course, it is also useful for extending a short width signal to a desired width. Various other applications are also possible. 532 Selection switch and timer operation Setting Operation mode Light-ON operation LIGHT ON Dark-ON operation DARK ON Sensing condition Light Dark Timer operation mode Operation Light received normal operation Light received ON-delay Light received OFF-delay T Light received ONE SHOT T Light interrupted normal operation Light interrupted ON-delay Light interrupted OFF-delay Light interrupted ONE SHOT ON OFF ON OFF ON T T T OFF ON T T OFF ON T T T OFF ON OFF ON T OFF ON T T T OFF Timer period: T=0.05 to 5 sec.
