Pepperl+Fuchs 264205

The triangulation sensor with background suppression, designated as OBT15-R2-E0-Y264205, is engineered for standard applications and offers a compact form factor. It has a detection range varying from 2 to 15 mm, optimized for detecting standard white targets measuring 100 mm x 100 mm.

Powered by a modulated visible red light LED at 630 nm, the device maintains a black-white difference of less than 5% at 15 mm. The light spot diameter is approximately 2 mm at this distance, with an angle deviation of around 2 degrees. It operates effectively under ambient light conditions up to 30,000 Lux, complying with the EN 60947-5-2 standard.

For functional safety, the sensor has a mean time to failure (MTTFd) of 800 years and a mission time (TM) of 20 years, with no diagnostic coverage. Operational indicators include a green LED for power and a yellow LED that signals when an object is detected.

Electrical specifications include an operating voltage range of 10 to 30 V DC, with a no-load supply current of less than 10 mA. The output is configured as a normally open contact with a single NPN output that is short-circuit and reverse polarity protected, capable of handling a maximum switching voltage of 30 V DC and a current of 50 mA on resistive loads. The switching frequency is approximately 800 Hz, with a response time of 600 µs.

The sensor is designed for a wide ambient temperature range of -25 to 60 °C and can withstand storage temperatures as low as -30 °C ... [Read more]
