Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they can be fussy to get adjusted ...

The reflective properties of plastic make it a notorious offender in this regard. The problem even extends to those objects covered in shrink wrap. Polarizing filters help block false readings from ...

TT Electronics has announced its OPB735 series Reflective Object Sensors for challenging industrial automation and safety applications. This reflective sensor features hermetically sealed components ...

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

The CLI700 reflective object sensor consists of an 880-nm aluminum-gallium-arsenide (AlGaAs) infrared emitter and an npn, buffered, open-collector IC. Both are mounted on a custom, four-leaded TO-72 ...

The EQ-34-PN-J is a photoelectric sensor with adjustable range reflective and PNP open collector by Panasonic. The device has a minimum operating supply voltage of 10 VDC. The device hardly gets ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

Leuze has introduced a broad range of stainless steel optical detectors for the food industry. “The devices are designed for reliable operation in wet areas and during intensive cleaning processes and ...
