Miniature photoelectric switches series W4-3: The efficient space savers

Transcription

1 iniature photoelectric switches series W-: The efficient space savers Photoelectric reflex switch with switching threshold adaptation and autocollimation. Transparent objects of all kinds can be reliably detected in difficult and changing ambient conditions, with the switching threshold being automatically adapted to the changing ambient conditions, such as dust gathering on the optical surfaces. D ATA SH E E T Photoelectric proximity switches BGS Photoelectric reflex switches Through-beam photoelectric switches IIt is the little things that make you big : minimum size, maximum versatility. Three versions of the W- series offer the users the following benefits for their application: Clearly visible light spot. The integration of new pinpoint LEDs creates brilliant, tightly defined light spots. Thus, the photoelectric switches can be aligned easily and quickly, as the light spot is easy to see even in bright ambient conditions. Best background suppression in its class. Background suppression offering more than just a good black/white displacement, i. e. object detection in front of reflective and moving backgrounds. The sensor has a nd sender LED allowing the sensor to see spatially. Optimum ambient light suppression. The photoelectric proximity switch needs to detect objects directly in front of an energy-saving lamp or a fluorescent lamp no problem. Light from such sources is identified and suppressed. Hygienic and safe to use in aggressive environments. Hydrofluoric acid, coolants, alcohols etc. cannot affect the fully Teflon-encapsulated versions even when exposed for long periods.

2 W- Selection table Reliably solved with linear light spot featured in the WTB-: Continuous detection of honeycomb structured objects, Accurate positioning, irrespective of grooves or recesses in objects, Reliable detection of falling objects. WTB- Photoelectric proximity switch with background suppression Detection of objects, irrespective of colour and consistency, up to the predefined scanning distance Best background suppression Clearly visible light spot Photoelectric proximity switch WTBS- with laser-like light spot: detection of the inserted PC board, at a distance of 80 mm, with pinpoint accuracy. The reflecting background does not interfere with the sensor s performance if no tool carrier is clamped and the robot moves. Laser-like light spot in the WTBS- for: Accurate positioning of the light beam on the object, Reliable detection of small objects immediately in front of a background, Very good visibility of the light spot on the object. WL- and WLG- Photoelectric reflex switches Safe and easy mounting. The mounting holes are fitted with threaded metal bushes for added strength. uick and easy alignment using the clearly visible light spot. Detection of transparent objects with switching threshold adaptation. Photoelectric reflex switch WLGS- thinks and controls with: automatic switching threshold adaptation transparent objects with an attenuation of > 8% are reliably detected. Detection of transparent objects such as PET bottles, even with dust and moisture present, Implementation of the sensor close to the process, without expensive mounting systems, Clear visibility of the light spot aids the alignment of the sensor, from nearly all conceivable positions. WSE- Through-beam photoelectric switches Fast and reliable alignment of the sensors through brilliant light spot. SICK
