Before procurement teams confirm E3S-DBP21T, they typically review Omron SMPS 24V 10A, E3Fa Dp12 2M and Omron Sensors to double-check performance ratings, stock availability, and supplier credibility carefully.
Omron E3S-DBP21T Photoelectric Sensor
The Omron E3S-DBP21T Photoelectric Sensor is a transparent object detection, retro-reflective with MSR function offering a 3.5 m sensing distance (when using E39-R8) and PNP output for precise object detection. It operates on a 10β30 VDC power supply and is part of the Omron automation portfolio under the Omron Photoelectric Sensors category and the Omron E3S Series. With a red LED (624 nm) light source, 720 mW power consumption, 30 VDC load power supply voltage, 100 mA load current, 0.5 ms response time, M12 connector, and IP67 protection, it ensures highly stable performance in demanding industrial environments.
