The Omron F39-JD3B is a Omron Safety Component typically used together with Omron Safety Light Curtains to switch machine power, interlock contactors, and provide monitored safety outputs in industrial panels. It is often evaluated along with related models such as Omron F39-JGR3M-B88-D (3PST-NO main contacts, SPST-NC auxiliary contact, For receiver M12 connector, 0.3 m cable length), Omron F39-JD10B (3PST-NO main contacts, SPST-NC auxiliary contact, 10m cable length), and Omron F39-JGR3M-B88-D (3PST-NO main contacts, SPST-NC auxiliary contact, For receiver M12 connector, 0.3 m cable length) when engineers are matching main contacts, auxiliary contacts, and light curtain auxiliary outputs to the control scheme. Reviewing contact configuration, auxiliary signalling, output type, and cable length helps ensure that each safety relay or controller is correctly coordinated with the connected light curtain, contactors, and emergency circuits.
