B-Line Enhanced 50 Series Photoelectric Sensor

It's a through-beam photoelectric sensor, which means detection happens when an object breaks a light beam travelling between a separate emitter and receiver mounted facing each other across the gap. Unlike a retroreflective or diffuse sensor, there is no reflector or return path off the target, so you mount hardware on both sides of the opening or conveyor. If you only have access to one side, a through-beam setup is the wrong architecture for that spot.

Yes. The 1150E-6513 carries IP 67 and IP69K ratings, so it stands up to temporary immersion and to high-pressure, high-temperature washdown, which is the rating food and beverage plants look for. The housing is fiberglass reinforced plastic, and the operating range is -13 to 131 degrees F (-25 to 55 degrees C), so unheated warehouses and cold-weather loading docks are inside spec.

It is. The Enhanced 50 Series 1150E-6513 has built-in reverse polarity, short circuit and overload protection, so a swapped DC polarity or a shorted output at the load won't destroy the unit. A yellow LED shows power on, which is the first thing to look at when you're troubleshooting a dead circuit at the sensor.

Generally yes, and that's the main reason to pick this style. The 1150E-6513 works as a through-beam pair, where the light crosses the gap once from emitter to receiver instead of making a round trip off a reflector, so it holds up better when lenses get dusty or the target is dark, shiny or irregular. The tradeoff is wiring and mounting on both sides. If you can only mount on one side, use a retroreflective or diffuse sensor instead.

Order it as B-Line 1150E-6513. That is the manufacturer part number for the Enhanced 50 Series through-beam photoelectric sensor with the 2 m PVC cable, and it's the number to quote when standardizing spare sensors across a plant.
