The XUSL4E30H106NS1: The manufacturer's lifecycle stage is marked as current, so this light curtain is still an active catalog item — no phase-out notice, no last-time-buy window to worry about. Availability and current pricing get confirmed at quote time.
What a Light Curtain Means on the Floor
Out here in the grease, a light curtain like this one is your non-contact guard. It shoots a grid of infrared beams between a transmitter and receiver; if anything bigger than the resolution breaks that grid, the machine stops. The XUSL4E30H106NS1 sits in that safety circuit — typically wired to a safety relay or a safe PLC input — and it's got to survive the same washdowns and vibration the rest of the panel sees. IP-rated housings are what keep the coolant and dust out of the optics.
