Overview of DSBA1P

The DSBA1P is a PCB mount contactless Tilt Switch Sensor with ammonia-resistant terminals. The photo interrupter, rather than contacts, ensures high reliability. It has sealed construction for protection from environmental elements, including hydrogen sulfide, sulfur dioxide and nitrogen hydroxide. It has totally sealed body allows process compatibility for time saving automatic soldering and cleaning. Internal steel ball movement allows functionality 360° circumference rotation. The DS series switch is well suited to meet product safety concerns due to normally closed (ON) status. The crimped terminals ensure secure mounting and prevent dislodging during wave soldering.

Key Features

  • Space saving compact dimensions allow high density mounting
