10 Safety Precautions EJM/ Refer to Warranty and Limitations of Liability. WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Do not use the product in atmospheres or environments that exceed product ratings. EJM Designing Precautions for Correct Use Operation Note: The white part of the DIP switch indicates which setting is selected. Models without timer Models with timer Switch configuration D L D TIMER Operation selector Operation Selector L SW SW2 Selector switch for timer mode D L D L Switch selection Light-,, DC output switching element Dark-, DC output switching element Timing charts -delay -delay One-shot delay -delay -delay One-shot delay D TIMER Both SW and SW2 at "."

L D L D Output Contact If EJM/ is connected to a load with contacts that spark when the load is turned (e.g., a contactor or valve), the normally-closed side may be turned before the normally-open side is turned or vice-versa. If both normally-open output and normally-closed output are used simultaneously, apply an surge suppressor to the load. Refer to OMR s PCB s Catalog () for typical examples of surge suppressors.

11 EJM/ Wiring Connecting and Wiring We recommend connecting a cable with a conductor cross-section of. mm 2 and an outer diameter of 6 to 8 mm. Be sure to firmly tighten the cover in order to maintain waterproof and dustproof properties. The screw size of the conduit sockets is shown in the following table. 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. Recommended example Approx. 4 mm Approx. mm Model EJM-@ Power source Tc, Ta Tb Conduit socket thread size PF/2 Rubber bushing (provided)* Washer (provided)* Tightening nut (provided)* Designing Power Reset Time The Sensor is ready to detect within 2 ms after it is turned. If the Sensor and load are connected to separate power supplies, be sure to turn the Sensor first. Items Common to EJM and Wiring Connecting and Wiring DC SSR Output Models When using the DC SSR output model, the total of the load current for the Light- output (NO) and that for the Dark- (NC) should be ma If the total exceeds ma, the load short-circuit protection function will be activated (this function will be reset when the power of the Photoelectric Sensor is turned ). Others Ambient Conditions (Installation Area) The EJM will malfunction if installed in the following places. Places where the EJM is exposed to a dusty environment. Places where corrosive gases are produced. * These parts are not provided with models with a -US suffix. Recommended Crimp Terminal Dimensions (Unit: mm) Round type Fork type Emitter Receiver dia. min. 9 (After crimping).6 dia. min. 9 (After crimping) Places where the EJM is directly exposed to water, oil, or chemicals. Note: Use terminals with insulation tube (recommended crimp terminal:.2 to.). Others Terminal Protection Cover (Provided) 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). Emitter Receiver Terminal protection cover EJM
