If the operating environment at your plant is particularly hostile and wet,the W 24-2 series of photoelectric switches provides the necessary degree of reliability in detection.A plethora of device features makes this possible:
sturdy metal housing with enclosure rating IP 67 (with Teflon coating if required),
high insensitivity to ambient light,
scratch-resistant front screen cover made of plastic (also available with a glass cover),
front screen heating to prevent condensation under rapidly changing ambient temperatures,
complete range of accessories for hostile environmental conditions:weather hood,dust shield with air purge,cooling plate for water cooling,
separate series for use in potentially explosive areas (see W 24 Exi).

Operator-friendliness was also a prime consideration.The easily accessible terminal chamber,the rotatable plug,the simple alignment of the sensors thanks to visible red light and,finally,the different supply voltages (including two universal voltage versions for AC and DC power supplies) are all proof of this.

Various device types ¨C all with L -/cU L -approval ¨C are available.. The WS/WE 24-2 through-beam photoelectric switch is characterised by its enormous scanning range of up to 50 metres.Even the photoelectric reflex switch, with a scanning range of up to 22 metres (on PL 80 A reflector) leaves most other devices way behind.Finally the adjustable WT 24-2 photoelectric proximity switch with background suppres- sion:it provides large scanning distances of 1,200 mm for the red light version and 2,500 mm for the infrared version.
