(DINIEC 68-2-6) without mounting spur
150m/s
2
(DINIEC 68-2-6) with mounting spur
Shock resistance 150m/s
2
(DINIEC 68-2-6) (11ms)
Required feeding force 5N or less
Output signal Serial communication compatibility
Output cable 337 439 (17 pin coupling), 367 425 0 (20 pins), etc. (Note 1)
Connection cable Refer to the standard connection example in Chapter 3 and fabricate the cable.
Note 1. When the MR-J2SCLCBL02M-P-H is used, 367 425 (5m or less) can be connected directly.
2. The linear encoder (linear scale) is extremely sensitive to the operating temperature. When it exceeds 50
, an alarm may
occur. It is recommended to pay special attention to the operating temperature and secure the temperature change margins.
3. The battery (MR-BAT) is not required to configure an absolute position detection system.
