What type of sensor is this?

This is a photoelectric proximity sensor with background suppression. It is designed to detect objects directly, helping the sensor distinguish the intended target from background surfaces behind it.

What sensing range can I expect?

The stated sensing range is 100 mm to 2,500 mm. Actual performance depends on the reflectivity of the target. As a guide, light objects can be detected at longer distances than dark ones, with typical maximum ranges of about 2.5 m on white targets, around 1.8 m on grey targets, and around 1.3 m on black targets.

What is the benefit of background suppression?

Background suppression helps the sensor focus on the intended object rather than surfaces behind it. This is useful in conveyors, packaging lines, and handling systems where a reflective machine frame or backdrop could otherwise cause unwanted switching.

What light source does the sensor use?

It uses infrared LED light. This makes it suitable for reliable object detection in industrial environments where stable, non-contact sensing is required.

Is the output type fixed or selectable?

The unit provides selectable NPN and PNP switching output, and the switching logic can also be set for light or dark operation. This gives added flexibility when matching the sensor to existing control circuits.

What supply voltage is required?

The sensor operates from 10 V DC to 30 V DC. This voltage range makes it suitable for many standard industrial DC control panels and machine installations.

How fast does the sensor respond?

The response time is up to 500 microseconds, with a switching frequency of 1,000 Hz. This makes it appropriate for fast-moving automation tasks where rapid detection is important.

What is the maximum output current?

The maximum output current is 100 mA. This should be checked against the load being switched to ensure the connected device remains within the sensor's output rating.

How is the sensing distance adjusted?

The sensing distance is adjusted by potentiometer. This allows quick manual set-up when commissioning the sensor for different target positions or object types.

What electrical connection does it use?

It uses a terminal connection with an M16 gland. This style can be useful where a hard-wired installation is preferred over plug-in connector types.

Is this sensor suitable for harsh industrial environments?

It has an IP67 enclosure rating, a metal zinc die-cast housing, and an operating temperature range of -40 °C to +60 °C. These features make it well suited to demanding industrial environments where dust, moisture, and temperature variation are factors.

What are the physical dimensions?

The housing dimensions are 27 mm x 87.5 mm x 65 mm, and the weight is approximately 330 g. For installations with limited space, these details can help when checking fit and mounting positions.

What material is used for the optical front?

The optics material is PMMA plastic. This is commonly used in industrial sensors for durable optical performance.

Can this sensor be mounted with a bracket?

Yes. A compatible large mounting bracket is listed for the W24-2 series, which can help when a more secure or adjustable installation method is needed.

What kind of applications is this sensor commonly used in?

This style of sensor is commonly used for object presence detection, part counting, position checking, and product flow monitoring on industrial machinery. The 1016931 version is especially useful where non-contact detection and resistance to background interference are important.
