Overview
The SF4D-A44-01 is a Panasonic SF4D Type 4 Arm/Foot safety light curtain with 44 beams spaced at 40 mm pitch, yielding a 45 mm resolution and a protected height of 1750 mm. It covers a sensing range from 0.8 m to 15.0 m on a 24 V supply and carries an IP67 enclosure for washdown environments. Built-in Blanking and Muting functions allow the curtain to ignore fixed obstructions or temporarily bypass during material feed, reducing the need for external bypass modules.
Selection comparison
Compared to the SF4D-H80-01 Hand-rated curtain, the SF4D-A44-01 uses 44 beams at 40 mm pitch (45 mm resolution) versus 80 beams at 20 mm pitch (25 mm resolution). The Arm/Foot rating suits larger body-part detection where a 45 mm object is the minimum to detect; the SF4D-H80-01 is the choice when the guarded opening requires finger or hand detection at 25 mm resolution.
Lifecycle and sourcing
The SF4D-A44-01 is an active Panasonic catalogue item with no end-of-life notice. Lead time is confirmed per RFQ; the part is available through current distribution channels.
