Omron E3Z-B61 0.5M Photoelectric Sensor
Omron E3Z-B61 0.5M is a retro-reflective photoelectric sensor without the MSR function, specified for clear plastic bottle sensing across an 80 to 500 mm range. Its 660 nm red LED establishes the optical path between the sensor and reflector, while the NPN output transfers the switching state to compatible control equipment. Light-ON or Dark-ON operation can be selected according to the required machine logic. The sensor operates from 12 to 24 VDC and includes a 0.5 m pre-wired cable. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. Within the E3Z Series, the E3Z-B61 0.5M provides the short-cable configuration. Related clear bottle photoelectric sensors are available across Omron Industrial Sensor Products.

The Omron E3Z-B61 0.5M Photoelectric Sensor uses retro-reflective sensing without the MSR function for clear plastic bottle sensing across an 80 to 500 mm range. Its 660 nm red LED establishes the optical path between the sensor and reflector, while the NPN output transfers the switching state to compatible industrial control equipment. Light-ON or Dark-ON operation can be selected according to the required machine logic. The sensor operates from 12 to 24 VDC and includes a 0.5 m pre-wired cable. Maximum current consumption is specified at 30 mA, while response time is 1 ms maximum. The square housing uses PBT and denatured polyarylate materials, and the supplied specification states IP67 enclosure protection.
For an Omron clear bottle sensor requiring NPN output, selectable switching logic, and a short pre-wired connection, the applicable model is the E3Z-B61. Its listed 80 to 500 mm working range supports short-distance reflector-based sensing where transparent plastic containers are the intended target. The 12 to 24 VDC operating range supports common DC control systems, while the red LED provides a visible optical source for setup. The specification also matches searches for an Omron transparent object sensor and Omron retro-reflective NPN sensor. For the same E3Z-B61 configuration with a longer 2 m pre-wired cable, see the E3Z-B61 2M. The cable length is the primary stated difference between these two supplied variants.
