Electronic switches manufactures a wide range of infrared photoelectric through beam sensors for various applications. The unit is built-in amplifier type having infrared emitter, receiver and amplifier in robust die-cast abs plastic housing.It requires voltage of 10 to 24 v dc. Sensing range obtained is 3 m. Sensing range varies from1 m to 10 m for different models. Different models are available with front or side or top sensing arrangements and with pnp or pn output with normally open/normally closed logic selection. Short-circuit protection and reverse polarity protection are provided. All solid-state construction gives a long maintenance free life. Models are available with plate brass housing also. These switches have wide application in non-contact sensing, switching, controlling and regulating in various processes, plants, machines, machine tools, etc, for automation and control and are also very useful for textile and pharmaceutical industries.
