Banner Diffuse Photoelectric Sensor, Barrel Sensor, 400 mm Detection Range

Can be installed where space is the limiting factor but the versatility of a barrel sensor is still required.

Available in either NPN or PNP complementary (SPDT) outputs. Incorporated in this is the ability to use the N/C output as an N/O alarm output. The alarm output operates when the sensor’s excess gain in the light condition becomes marginal (drops to 1-1.5x). The load for both outputs must not exceed 150mA.
The fixed field units compare the reflection of the sensor’s emitted light beam from an object to two differently aimed detectors in the sensor head. This enables the sensors to detect an object that is only a short distance directly in front of another object or background, this distance can be as low as a few mm
Retro-reflective models have a special lens which polarises the emitted light and filters out unwanted reflections, making these sensors useable in applications otherwise unsuited to retro-reflective sensing.
The ac units are fitted with a solid state SPST relay capable of switching up to 300mA (continuous)

Got your sights set on tracking the position of an item in an industrial setting? This photoelectric sensor from Banner is just the tool for the job. It has a diffuse function, which means it works by emitting a continuous ray of light. When this light hits an object, it scatters across a surface, sending the signal back to the receiver. Background suppression blocks out surrounding objects so you can pinpoint the sensing range. The same unit houses the transmitter and receiver, so this device comes in handy for operations with limited space.

• Short-circuit and reverse-polarity protection to prevent electric hazards
• Withstands tough conditions thanks to a wide operating temperature range of -40°C to +70°C
• Stands up to mechanical shock and vibration for safe operation in heavy-duty equipment
• Tough PBT housing resists chemicals
• Typical response time of less than 3ms means you get rapid measurements

• Assembly lines
• Security systems
• Marine engineering
• Storage facilities

This sensor has a measurement range of 0 to 400mm, making it ideal for shorter-range detection.
