## **Photoelectrics Diffuse-reflective Type PA18CLD0.T, AC, PBTP-housing** - **Range: 400 mm adjustable 100, 200 or 400 mm fixed** - **Modulated, infrared light** - **Supply voltage: 20 to 250 VAC** - **Output: 500 mA SCR** - **Make or break switching function, LED indication** - **High immunity to ambient light** - **Cable and plug versions** ## **Product Descri tion p** The PA18CLD.. is a family of inexpensive general purpose Diffuse-reflective sensors in industrial standard 18 mm cylindrical PBTP housing. They are useful for simple applications where a basic sensor provides adequate sensing performance. The sensors are simple to use and no adjustment are ne - cessary (except 400 mm diffuse adjustable type). The output is a 2-wire NO or NC thyristor (SCR) output. ## **Ordering Key PA18CLD04TCM6SA** **Type Housing style Housing size Housing material Housing length Detection principle Sensing distance Output type Output configuration Connection type Adjustable** ## **T e Selection yp** **Housing Rated Ordering no.
