Fog preventing Small reflector Tape Reflector
Reflectors are not provided with Retro-reflective models. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. When using a Reflector without a rated value, use 0. 7 times typical value as a guideline for the sensing distance. [. . . ] The appropriate tightening torque is 0. 3 to 0. 4 N·m.
Precautions for Safe Use
Do not install the Sensor in the following locations.
(1) Locations subject to direct sunlight (2) Locations subject to condensation due to high humidity (3) Locations subject to corrosive gas (4) Locations where the Sensor may receive direct vibration or shock
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. If a load short circuit occurs, the output will turn OFF, so check the wiring before turning ON the power supply again. The load shortcircuit protection will operate when the current flow reaches 1. 8 times the rated load current. When using an L load, use an inrush current of 1. 8 times the rated load current or higher.
Connecting and Mounting
(1) The maximum power supply voltage is 30 VDC. Before turning the power ON, make sure that the power supply voltage does not exceed the maximum voltage. (2) Laying Sensor wiring in the same conduit or duct as high-voltage wires or power lines may result in malfunction or damage due to induction. As a general rule, wire the Sensor in a separate conduit or use shielded cable. (3) Use an extension cable with a minimum thickness of 0. 3 mm2 and less than 100 m long. (5) Pounding the Photoelectric Sensor with a hammer or other tool during mounting will impair water resistance. (6) Mount the Sensor either using the bracket (sold separately) or on a flat surface. (7) Be sure to turn OFF the power supply before inserting or removing the connector.
Do not use the Sensor in water, rainfall, or outdoors.
When disposing of the Sensor, treat it as industrial waste. Mounting Diagram
Mounting Bracket (sold separately) E39-L104 Use a mounting torque of 0. 5 N·m max.
Resistance to Detergents, Disinfectants, and Chemicals
· Performance is assured for typical detergents and disinfectants, but performance may not be maintained for some detergents and disinfectants. · The E3ZM passed testing for resistance to detergents and disinfectants performed using the items in the following table. Refer to this table when considering use of detergents and disinfectants.
Category Product name Sodium hydroxide (NaOH) Phosphoric acid (H3PO4) Sodium hypochlorite (NaCIO) Hydrogen peroxide (H2O2) Alkaline foam detergent Acidic foam detergent P3-topax-66s (Manufactured by Ecolab) P3-topax-56 (Manufactured by Ecolab) P3-oxonia active 90 (Manufactured by Ecolab) Disinfectant Concentration 1. 5 % 2. 5 % 0. 3 % 6. 5 % 3. 0 % 5. 0 % 1. 0 % Temperature 70 °C 70 °C 70 °C 25 °C 25 °C 70 °C 70 °C 25 °C Time 240 h 240 h 240 h 240 h 240 h 240 h 240 h 240 h
Never use thinner or other solvents. Otherwise, the Sensor surface may be dissolved.
If a commercial switching regulator is used, ground the FG (frame ground) terminal.
Power Supply Reset Time
The Sensor will be able to detect objects 100 ms after the power supply is tuned ON. Start using the Sensor 100 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.
Potassium hydroxide (KOH) 1. 5 % Chemical
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.
TEK121 (Manufactured by ABC 1. 1 % 25 °C 240 h Compounding) Note: The Sensor was immersed in the chemicals, detergents, and disinfectants listed above at the temperatures in the table for 240 hours and then passed an insulation resistance of 100 M min.
