Pepperl+fuchs india supplies photoelectric sensors for hazardous areas. Modern optical sensors are also an indispensable pre-requisite for automated production in hazardous areas. The company now provides a variety of ranges with different photoelectric versions for use in hazardous areas. Products in the mlv11, rl36 and varikont m series are especially applicable to use in areas where an explosive atmosphere is occasionally encountered [a mixture of air and flammable gases, vapours, mists]. These intrinsically safe sensors enable adjustment during normal operation, without reducing the level of explosive safety. Some of the salient features includes : all devices come with namur output, wire-programmed no/nc contacts; wire-programmed light/dark switching; standard sensitivity and sensing range adjuster; operating temperature -25ºc… +70ºc; and varikont m series with adjustable sensor head.
