Festo
The Festo 552138 is a pneumatic industrial component utilizing a pneumatic measuring principle to detect distance across a sensing range of 20 µm to 200 µm with a repetition accuracy of ±2.5 µm. Operating at a pressure range of 4 bar to 7 bar with a supply pressure of 0.8 bar to 1.6 bar, it functions within a DC operating voltage range of 22.8 V to 26.4 V and features a 2xPNP switching output with a max output current of 100 mA and short-circuit protection. This RoHS compliant device carries RCM compliance, c UL us recognition, KC-EMV, and CE and UKCA markings as per EMC and RoHS directives, operating with compressed air per ISO 8573-1:2010 [7:4:4] within an ambient temperature range of 0 °C to 50 °C.
