140 EE-SX3161-W11/4161-W11 Photomicrosensor (Transmissive)
Photomicrosensor (Transmissive)
EE-SX3161-W11/4161-W11
■ Dimensions
Note: All units are in millimeters unless otherwise indicated.
■ Features
• Dust-proof model.
• Light-receiving element and amplification circuits contained in one
chip.
• Can use a power supply voltage of 4.5 to 16 V.
• Connects directly to C-MOS or TTL.
• Dark-ON Sensor: EE-SX3161-W11
• Light-ON Sensor: EE-SX4161-W11
• Pre-wired Sensors (AWG28).
• Solder-less lead wire connection to increase reliability.
■ Absolute Maximum Ratings (Ta = 25C)
Note: 1. Refer to the temperature rating chart if the ambient tem-
perature exceeds 25C.
2. If you mount the Sensor with screws, use M3 screws, and
flat washers and use a tightening torque of 0.5 N·m max.
