E3H2-R2 a) standard mode To teach the retro-reflective model E3H2-R, place the sensor with the lens facing the reflector. For remote teach connect the white wire (Pin 2) for 2-5 seconds to common (-). for semi-transparent models) To teach the retro-reflective model E3H2-R in high sensitivity mode, place the sensor with the lens facing the reflector. For remote teach connect the white wire (Pin 2) for >8 seconds to common (-).

High-temperature environments may result in burn injury. Precautions for Safe Use The following precautions must be observed to ensure safe operation of the Sensor. Cleaning Never use thinner or other solvents. Otherwise, the Sensor surface may be dissolved. Operating Environment Do not use the Sensor in an environment where explosive or flammable gas is present. Power Supply If a commercial switching regulator is used, ground the FG (frame ground) terminal. Connecting Connectors Be sure to hold the connector cover when inserting or removing the connector. Be sure to tighten the connector lock by hand; do not use pliers or other tools. If the tightening is insufficient, the degree of protection will not be maintained and the Sensor may become loose due to vibration. The appropriate tightening torque is 0. 4 to 0. 5 N·m for M12 connectors and 0. 3 Nm for M8 connectors. Power Supply Reset Time The Sensor will be able to detect objects 150 ms after the power supply is tuned ON. Start using the Sensor 150 ms or more after turning ON the power supply. If the load and the Sensor are connected to separate power supplies, be sure to turn ON the Sensor first. Turning OFF the Power Supply Output pulses may be generated even when the power supply is OFF. Therefore, it is recommended to first turn OFF the power supply for the load or the load line. Load Do not use a load that exceeds the rated load. Environements with Cleaners and Disinfectants Do not use the Sensor in environments subject to cleaners and disifectants. They may reduce the degree of protection. Load Short-circuit Protection This Sensor is equipped with load short-circuit protection, but be sure to not short circuit the load. Be sure to not use an output current flow that exceeds the rated current. Modifications Do not attempt to disassemble, repair, or modify the Sensor. Water Resistance Do not use the Sensor in water, rainfall, or outdoors. Outdoor Use Do not use the Sensor in locations subject to direct sunlight. Cleaning Do not use thinner, alcohol, or other organic solvents. Otherwise, the optical properties and degree of protection may be degraded. Surface Temperature Burn injury may occur. The Sensor surface temperature rises depending on application conditions, such as the surrounding temperature and the power supply voltage. Use caution when operating or washing the Sensor. 10 Miniature Photoelectric Sensors E3H2 11 WARRANTY OMRON's exclusive warranty is that the products are free from defects in materials and workmanship for a period of one year (or other period if specified) from date of sale by OMRON.
