Product Description:
The BL-MP400J-20SNB indicator from a top brand Okuma mounts directly to BL Servo Motors electronics with a blue LED color, ensuring a clear status feedback in dimly lit control cabinets. It emits light at a 470 nm wavelength which combines with peak photodiode sensitivity for reliable optical monitoring. It also delivers a luminous intensity of 20 mcd just to remain visible under bright factory lighting conditions. These optical characteristics of this module enable instant recognition of motor drive states during setup and diagnostics.
This motor part draws a forward current of 20 mA for a balance brightness, thermal load and continuous operation. It accepts a forward voltage of 3.0 V typical and 4.0 V maximum which matches standard LED drivers to simplify power-supply design. It withstands a reverse voltage of 5 V, preventing damage if polarity is accidentally reversed during wiring. The variant provides a wide 120° viewing angle and spreads illumination across large panel windows for multi-operator readability. It installs via a through-hole mounting type and protects the component against vibration in moving machinery. Also, it comes in a 4 mm round package and uses a water clear lens type which maximizes light output without diffusion loss.
This indicator type works on -40 °C to +85 °C range and thereby covers both freezer startups and hot spindle-room environments without failure. It stores safely between –40 °C and +100 °C to safeguard components during transport and storage. BL-MP400J-20SNB complies with RoHS directives which further excludes hazardous substances for environmental safety. It tolerates pulse forward currents up to 100 mA which allows brief high-intensity signaling during fault alerts. The component can exhibit a reverse current of no more than 10 µA at 5 V for reducing leakage and standby power draw.
Frequently Asked Questions about BL-MP400J-20SNB:
Q: How does the BL-MP400J-20SNB cope with extreme cold?
A: The BL-MP400J-20SNB operates down to –40 °C which maintains LED function in freezer-storage conditions. It prevents flicker or failure at low temperatures.
Q: Can the BL-MP400J-20SNB handle brief overdrive pulses?
A: The motor tolerates pulse forward currents up to 100 mA which enables high-intensity flash signaling. It avoids damage during short-duration alert bursts.
Q: What makes the BL-MP400J-20SNB visible across wide panels?
A: It offers a 120° viewing angle which spreads light broadly. This also ensures status indication can be seen from multiple operator stations.
Q: Is the BL-MP400J-20SNB compliant with environmental standards?
A: The BL-MP400J-20SNB is RoHS compliant which omits lead and mercury. It supports eco-friendly disposal and manufacturing.
Q: How does the BL-MP400J-20SNB integrate on PCBs?
A: The device comes in a 4 mm round package which fits standard hole layouts. It simplifies board design without custom drill patterns.
