The 507-4756-3331-500F is a red LED indicator light from Dialight's 507 series, featuring incandescent wire leads and intermediate screw terminal connections. The device is housed in a short cylindrical fresnel plastic cap with an unfrosted or transparent finish, mounted via a 1-3/16" mounting hole with black anodized metal hardware. This RoHS-compliant indicator is designed for panel-mount applications requiring reliable visual signaling. The combination of screw terminal connectivity and fresnel optics makes it suitable for industrial control panels, equipment status indication, and alarm systems where durable, long-lasting illumination is required.
