The IDEC SA1U-B02MT is a versatile background suppression switch with a 2-meter range and four sensing methods: through-beam, polarized retro-reflective, diffuse, and background suppression. It offers an extensive sensing range of up to 50 meters and features an adjustable time delay from 0.1 to 5 seconds for tailored operation. Designed with interference prevention, it permits the close mounting of two units without signal disruption. Additionally, its spring-up terminal block structure simplifies wiring processes for efficient installation.
