The 1770 mm protective height and 0.2 m to 7.0 m operating range cover a full-height entry zone on a typical machine cell or conveyor line. The 24 VDC supply is standard for safety circuits; plan for a dedicated safety-rated power supply or a fused tap from the machine's 24 VDC bus. ## Key specs that decide fit 36 beams at a 50 mm beam pitch create the 1770 mm protective column. The 50 mm spacing is what sets the 55 mm detection capability — a 55 mm diameter object anywhere in the field breaks at least one beam. That is the number that governs whether this curtain meets the required safety distance per ISO 13855 for your application. Built-in blanking and muting functions are standard on this model. Blanking lets you ignore fixed obstructions (like a machine frame passing through the field) without disabling the entire curtain. Muting temporarily suspends the safety output during a defined material pass cycle — common on conveyor infeed/outfeed stations. Both are configured via the controller, not dip switches on the sensor head.","metaTitle":"Omron F3SJ-A1770P55 Light Curtain, 55mm Detection, 1770mm He","metaDescription":"Omron F3SJ-A1770P55 safety light curtain, 55mm detection capability, 1770mm protective height, 36 beams at 50mm pitch.
