Festo
553545
Proximity sensor SIEF-M18B-PS-S-L
The Festo 553545 is a round M18 industrial component featuring a flush mounting type and a 5 mm rated operating distance that conforms to EN 60947-5-2. This RoHS compliant device operates on a 10 V to 30 V DC voltage range, providing a PNP switching output with a N.O. contact function, a max. switching frequency DC of 2500 Hz, and a max. output current of 200 mA. It includes pulsed short-circuit protection, reverse polarity protection for all electrical connections, and a 3-pin M12x1 plug electrical connection with a chrome-plated brass plug housing. Certified with the RCM compliance mark and c UL us - Listed (OL), it carries CE and UKCA markings as per EU and UK directives for EMC, low voltage, and RoHS, while operating within an ambient temperature range of -30 °C to 85 °C with a repetition accuracy of 0.28 mm.
