CSM_E3Z_DS_E_15_1
Compact Photoelectric Sensor with Built-in Amplifier
E3Z
The Standard for Photoelectric Sensors
with a Secure Track Record of One
Million Sold Yearly.
• Long sensing distance of 30 m for Through-beam Models, 4 m for
Retro-reflective Models, and 1 m for Diffuse-reflective Models.
• Mechanical axis and optical axis offset of less than ±2.5
° simplifies
optical axis adjustment.
• High stability with unique algorithm that prevents interference of
external light.
Be sure to read Safety Precautions on
page 15.
Features
Industry's Top-level Sensing Distance with
Built-in Amplifier
A separately sold filter is available to prevent mutual interference for
Through-beam Models with red lights sources and a sensing
distance of 10 m. Reflective Models include functionality to prevent
mutual interference.
Long-distance, Through-beam Sensors with a detection distance of
30 m (response time: 2 ms) are also available.
Low-temperature Operation for Applications in Cold-storage Warehouses
A wider ambient operating range from −40 to 55°C (main models with connectors). We also provide Sensor I/O Connectors with PUR Cables for
high resistance to cold environments.
Improved Matching of Optical Axis and Mechanical Axis for
Through-beam Models and Retro-reflective Models
The offset between the optical axis and the mechanical axis is kept within ±2.5°, so the optical axis can
be accurately set simply by mounting the Sensor according to the mechanical axis.
Sensor Protection against Incorrect Wiring
The Sensor includes output reverse polarity protection.
(A diode to protect against reverse polarity is added to the output line.)
Complete Compliance with the EU's RoHS Directive
Lead, mercury, cadmium hexachrome, polybrominated biphenyl (PBB), and polybrominated
diphenyl ether (PBDE) have all been eliminated. Also, burnable polyethylene packaging has
been used.

Mounting Brackets A Mounting Bracket is not enclosed with the Sensor. Order a Mounting Bracket separately if required.
[Refer to Dimensions on E39-L/F39-L/E39-S/E39-R]
Note: 1. When using Through-beam models, order one bracket for the Receiver and one for the Emitter.
2. Refer to Mounting Brackets on E39-L/F39-L/E39-S/E39-R for details.
*1. Cannot be used for Standard Connector models with mounting surface on the bottom. In that case, use Pre-wired Connector models.
*2. Cannot be used for Standard Connector models.
Sensor I/O Connectors
(Models for Connectors and Pre-wired Connectors: A Connector is not provided with the Sensor. Be sure to order a Connector separately.)
[Refer to Dimensions for XS3, XS2, XS5. For e-CON, inquire.]
Note: When using Through-beam models, order one connector for the Receiver and one for the Emitter.
*1. Refer to Introduction to Sensor I/O Connectors for details.
*2. The Sensor can be used in low-temperature environments (−25°C to −40°C). Do not use the Sensor in locations that are subject to oil.
*3. The connector will not rotate after connecting.
*4. The cable is fixed at an angle of 180° from the sensor emitter/receiver surface.
