BL-MT300M-20SN
by Okuma
The BL-MT300M-20SN is an advanced indicator assembly from Okuma within the BL Servo Motors series, combining precision status signaling with rugged mounting capabilities. It incorporates a green diffused lens fitted over a 3mm (T-1) LED to deliver a clear visual cue in industrial environments. Rated for a forward voltage of 2.2V and a forward current of 20mA, this module achieves a luminous intensity of 8 mcd while consuming minimal power. The device is engineered to operate reliably across an extreme temperature range from -25°C to 85°C, ensuring consistent performance under harsh conditions. With a radial package/case, the component integrates seamlessly into through-hole printed circuit board assemblies.
The technical capabilities of this indicator include a viewing angle of 60° for broad visibility and a peak emission wavelength of 565 nm, which produces a vivid green indication optimized for human perception. The lens shape, specified as round with a flat top, enhances both diffusion and directional clarity. The polarity is clearly marked by the cathode marker to prevent assembly errors and facilitate rapid production line integration. Rated at a mounting type of through hole, the component offers mechanical stability and vibration resistance when soldered into place. The combination of low forward current requirements and high luminous output underscores its efficiency in energy-sensitive applications.
From an operational standpoint, the module’s lens color and geometry are designed to maintain consistent brightness over extended duty cycles, minimizing drift and visual fatigue for operators. The device tolerates a maximum junction temperature well above typical ambient levels, translating to robust lifetime reliability. Its package/case design provides uniform heat dissipation around the body, which contributes to the stable thermal profile required in continuous-duty industrial signaling tasks. Installation is straightforward thanks to standardized lead spacing and the clearly defined cathode marked lead, which expedites troubleshooting and reduces assembly downtime.
Integration of the BL-MT300M-20SN indicator is seamless in control panels, status boards, and servo-driven machinery, where real-time feedback on system states is essential. Its compatibility with through-hole PCBs and standard 3mm LED apertures ensures direct drop-in replacement for legacy indicators without redesign. Engineers can leverage the consistent forward voltage and forward current specifications to design accurate sensing circuits and drive electronics. With its combination of precise optical characteristics and durable construction, the BL-MT300M-20SN serves as a versatile solution for signaling in automation, robotics, CNC machinery, and other industrial control applications.
