Product Description
Milesight EM500-UDL-915M PN: C100 Ultrasonic Distance and Level Sensor is a wireless, non-contact ultrasonic sensor for measuring object distance and tank or liquid level. The C100 variant has a manufacturer-specified 0.25–10 m measurement range, 1 mm resolution, and accuracy of ±(1 + 0.3% × S) cm, S = distance, as written in the Milesight datasheet. Unlike the W-series models, this C100 specification does not use a ±1% full-scale accuracy figure.
C100 physical specifications: IP67 enclosure, black-grey ABS + PC housing, operating temperature −15°C to +60°C, relative humidity 0–80% non-condensing, dimensions 156.1 × 71 × 69.5 mm, and approximate weight 362.7 g including the battery and mounting bracket. Supported installation methods are pole, wall or DIN-rail mounting. Leave at least 0.25 m to the measured target and consult the manufacturer’s C100-specific ultrasonic beam pattern to assess site suitability.
The sensor communicates using LoRaWAN® OTAA/ABP Class A and Milesight D2D via an internal antenna. NFC mobile-app configuration, local USB Type-C PC software/console configuration, and remote parameter changes by LoRaWAN downlink are supported. The EM500-UDL can retain 1,000 local readings and supports data retransmission, retrieval, threshold alerts and change alarms. A replaceable 19,000 mAh ER34615 Li-SOCl₂ battery has a manufacturer laboratory endurance estimate of 10 years at a 10-minute interval and 25°C; actual lifespan varies.
Important regional and picture notes: TwoElectrons SKU 2ESE2181 refers to EM500-UDL-915M, PN C100. Although the OEM lists IN865 among available regional frequencies, the supplied 915M unit’s compatibility with India’s IN865 band requires confirmation. The manufacturer’s product-family illustration is shown for reference; the C100 housing is specified as black-grey and may differ from the grey illustration. Only C100 measurement and physical specifications are used on this page.
