Specifications Appendix A
E3C-MA11 Photoelectric Module
Note The 10-ms OFF-delay timer function can be turned OFF.
E2C-MA11 Proximity Sensor Module
Note 1. Perform positioning teaching within the stable sensing range. Even if teaching is performed success-
fully outside the stable sensing range, the E2C-MA11 in operation may not reset properly. Further-
more, even if teaching is performed successfully with or without a sensing object, the E2C-MA11 may
not reset properly after a delicate change is detected.
2. With no surrounding metal or background objects.
3. Off-delay timer can also be turned off with a switch.
