Note 3) For detailed specifications other than the above, refer to the separate technical operation manual that can be downloaded from SMCs website (http://www.smcworld.com/). 10 to 150 Hz with a 0.035 mm amplitude or 4.9 m/s2 in each X, Y, Z direction for 2 hrs (De-energized) 147 m/s2 in each X, Y, Z direction, 3 times (De-energized) Standard CE marking, UL (CSA) Communication connector

When excessive impact (300m/s2 or more) is applied to a reed switch during operation, the contact point will malfunction and generate or cut off a signal momentarily (1ms or less). Consult SMC regarding the need to use a solid state switch depending upon the environment. 7. Do not use in an area where surges are generated.

Do not drop, bump, or apply excessive impact (PSE540: 980 m/s2, PSE560: 500 m/s2) while handling. Although the body of the sensor may not be damaged, the inside of the sensor could be damaged and lead to malfunction. 2. The tensile strength of the cord is 50 N. Applying a greater pulling force to it can cause malfunction.
