Product Description:
The BL-MC25J-30TB indicator, from Okuma, utilizes the blue LED color that improves sightings in dimly lit machine-tool environments. The lid design possesses a transparent lens color that provides direct light transmission and eliminates color distortion. It is installed through the through-hole mounting type assuring that the device is firmly fixed on the PCBs and vibration-induced loosening passively resists. This LED draws a forward current of 30 mA which ensures bright illumination without overloading control circuits.
The motor drops a forward voltage of 3.2 V typical which aligns with standard driver outputs to simplify power regulation. It emits a luminous intensity of 250 mcd at IF=20 mA, guaranteeing clear status indication under bright shop lighting. The module radiates at a wavelength of 470 nm typical which matches peak sensitivity of blue-sensitive photodetectors for reliable optical sensing. It offers a viewing angle of 30° which concentrates the beam for targeted panel indication. It withstands a reverse voltage of 5 V for preventing damage from accidental polarity reversal in wiring. The unit handles a power dissipation of 120 mW by avoiding a thermal overload during continuous operation.
The device tolerates an operating temperature range of −40°C to +85°C that covers freezer startups and hot spindle-room conditions. It also survives storage temperatures from −40°C to +100°C which ensures component integrity during shipping and warehousing. It endures soldering temperatures of 260°C for 5s, supporting lead-free reflow assembly processes. It presents a junction capacitance of 50 pF and limits signal distortion in high-speed optical circuits. This model achieves an expected service life of 50000 hours to reduce maintenance intervals and support long-term reliability.
