Product overview

The Meskernel LDJ-100 uses optical technology for laser distance measurement and provides a digital output. Its measurement range is 0.03–100m indoors under the stated 90% condition, with ±2mm accuracy and ±2mm resolution. The Class II module operates at 3Hz and accepts a DC 2.5–3.3V supply. Its data interface choices include TTL, RS232, RS485 and 4–20mA, providing several connection options within the LDJ-100 product offering.

The module measures 64 × 40 × 18mm and weighs about 13g. Its operating temperature range is -40 to +60°C, while its storage temperature range is -25 to 60°C. Meskernel offers OEM, ODM and OBM customization support, with options covering temperature, communication interface, baud rate, frequency, precision and measuring range. The LDJ-100 is supplied in neutral packaging.
