Optimized for Automotive and Machine Tool Industries

The BJR series oil-resistant/oil-proof photoelectric sensors are optimized for use in various environments with cutting oil and lubricants such as automotive and machine tool industries.

BJR Series Oil-Resistance/Oil-Proof Test Results

The product has passed oil resistance tests for IP67G and IP67F protection rating (JEM standard). Oil-resistance may be affected by certain types of oil. Refer to the following table when considering oil types.

Various Connection Types Available

The BJR series is available in connector type, cable type, and cable connector types, allowing easy application in various user environments.

Long Sensing Distance Up to 15 m

Through-beam type models feature long sensing distances up to 15 m. Sensing distance: retroreflective type 3 m / diffuse reflective type: 1 m

M.S.R (Mirror Surface Rejection) Function (Retroreflective Type)

The retroreflective type models feature MSR (Mirror Surface Rejection) function which allow the units to only receive light from specific mirrors (MS-2S). This function allows stable detection of highly reflective targets including metals, mirrors, etc.

The Working Principle of Mirror Surface Rejection (MSR) Function

The light passed through the polarizing filter on the emitter will become horizontal. The light reflected on the retroreflective mirror will turn 90˚ and the vertical light will be received by receiver through vertical polarizing filter.

The light reflected from reflective targets will remain horizontal, and thus will not be received by the receiver with the vertical polarizing filter.

Mutual Interference Prevention Function (Except Through-Beam Types)

The emitter cycles can be configured so that the sensors will not be affected by other nearby sensors. This allows adjacent installation of multiple sensors.

Excellent Noise Immunity and Minimal Influence from Ambient Light

The sensors feature noise reduction algorithm and digital filters, offering excellent noise immunity and minimal influence from ambient light.

IP67 Protection Structure (IEC Standard), IP67G/IP67F Protection Structure (JEM Standard)

IP67 protection structure allows stable and error-free operation even in wet or dusty environments. IP67G/IP67F protection structure allows stable and error-free operation even in oily environments.
