A 50 m-class single-line TOF scanner that speaks to both sides of the machine: Ethernet scan data for your software, a hardwired NPN or PNP switching signal for your panel.
Integrators usually face a false choice: a data-only LiDAR that needs software before anything can react, or a simple switching sensor that reacts but tells you nothing. The DLD50T8N/P refuses the choice. Its Ethernet 100BASE-TX port streams full scan data for navigation, monitoring or recording, while its discrete NPN (T8N) or PNP (T8P) output drives a wire-level signal your PLC, alarm chain or slow-down circuit acts on directly.
The published T8 data describe single-line TOF ranging across a 280° window, dual-rated at 50 m (90% remission) / 20 m (10%) with ±30 mm accuracy, in the same 60 × 60 × 80 mm, 250 g, IP67 body running from 9–36 V DC. If you only need the data channel, the plain DLD-50D is the cleaner buy; the T8 exists for machines that must also switch something.
Original DAIDISIKE schematic: the network path informs, the wire path acts — both live in the same 250 g housing.

Open items we will confirm in writing rather than guess: discrete channel count and drive rating, Ethernet application protocol, operating temperature, connector pinout, power draw. Request the documents for the exact T8 variant. The DLD-50D reference manual below describes a different listed model family and does not replace a T8-specific pinout or communications protocol.
A useful enquiry starts with what your controller must do, not just the maximum distance on the data sheet. Use these four checks to make the N/P choice and prepare an evaluation that reflects your actual machine.
Share the PLC or input-module model, its common-terminal arrangement and the signal you need. Confirm output loading, normal and fault states, and the exact connector drawing. Our NPN/PNP wiring guide explains the electrical concepts; it is not a T8 pinout.
State the nearest and farthest target, its size, colour and surface, and the mounting height. Include dark or angled objects in the trial. The quoted reflectivity figures are test conditions, not a promise that every object will be detected at the same distance.
Tell us your host controller, operating system and required scan-data format. Ethernet 100BASE-TX identifies the physical interface; it does not by itself confirm a supported PLC protocol, software driver or SDK. Request those details for the delivered hardware and firmware.
Check scan data and the discrete signal with representative targets, then verify the defined behaviour at start-up, lost communication and power interruption. For a mobile platform, review the distinction between navigation LiDAR and a safety scanner.
Send your PLC model, required NPN/PNP signal, working distance, target photos, installation sketch and quantity through our application enquiry page. These details help us confirm the correct variant and supporting documents before you commit to a machine design.
English manual, 22 pages, approximately 25.5 MB. This is the supplied DLD-50D reference for the listed DH/DC/DP variants. It does not list DLD50T8N or DLD50T8P. Use it for platform background, not as authorisation to reuse its wiring, registers or configuration on a T8 unit.
The PDF opens only when requested; it is not loaded with this product page. For commissioning, request the T8-specific electrical drawing, I/O ratings and communication documentation.
Give a ladder-logic machine LiDAR ranging through the discrete input it already understands — Ethernet stays available for later upgrades.
Point clouds feed navigation while the hardwired output supports ordinary warning or process-control logic. Validate response time and keep personnel-protection functions on a separate, suitable safety system.
Stackers, gantries and RTG-class equipment use the 280° sweep and 50 m/20 m dual rating for staged approach warnings.
Drop into panels built around switching sensors — no fieldbus re-engineering — while logging scans over Ethernet.
Because most retrofit and mobile-machine projects have two consumers: software that wants the full scan (navigation, monitoring, logging) and a control panel that wants a plain switching signal it can wire today. The DLD50T8N/P serves both simultaneously — 100BASE-TX Ethernet for the data path, hardwired NPN or PNP for the interlock path — so you mount, wire and maintain one sensor instead of two.
Match the sensor output to the actual PLC input circuit, not just a label on the input card. DLD50T8N has an NPN sinking output and DLD50T8P has a PNP sourcing output; confirm the compatible input, common terminal and wiring with the controller documentation. The published variant table lists the N model at 50 Hz with 0.08°/0.16°/0.32° resolution and the P model at 100 Hz with 0.32° resolution. Confirm the ordered suffix and configuration before wiring.
The discrete output provides a separate hardwired input to ordinary control or warning logic, but scan frequency alone does not establish total response time. Confirm sensor response, output behaviour and PLC processing for the ordered model, then test the complete chain. It is not an OSSD or a certified personnel-protection output; a hardwired connection does not make it one.
No. This is a perception/measurement LiDAR, not an IEC 61496 certified safety component; do not use it as the sole means of personnel protection. The discrete output is not an OSSD and no Type, SIL or PL rating is published. When the risk assessment demands a protective device, that is our ST27 Type 3 safety laser scanner — and the two roles should not be blurred in the design review.
The dual rating is 50 m at 90% remission and 20 m at 10% remission, with ±30 mm accuracy. Tyres, rubber skirts, dark housings and dark clothing behave like the 10% case, so trip distances and slow-down bands for dark targets belong inside the 20 m envelope. The 50 m figure is real, but only for bright, cooperative surfaces.
The channel count and drive current of the discrete I/O, the Ethernet application protocol above the 100BASE-TX layer, the operating temperature range, connector pinout and power draw are not in the factory sheet we hold. We flag them rather than invent them — send your integration details and we will confirm each point in writing before you order.
No. The supplied reference manual lists DLD-50DH, DLD-50DC and DLD-50DP, not DLD50T8N or DLD50T8P. It is provided for background on the DLD-50D platform. Do not transfer its connector pinout, communications settings or parameter values to a T8 unit without written model-specific confirmation. Request the T8 drawing and protocol for your ordered suffix before commissioning.
MOQ 1 unit; a bench evaluation against your actual PLC input card is the fastest way to settle the N/P choice. Typical lead time is 3–15 days by variant and quantity, confirmed on the quotation. Factory-direct export from China; OEM/ODM cooperation on cabling, labelling and preset zone parameters is available for volume programs through the inquiry form.
