APPLICATION
LiDAR Connector
LiDAR puts three demands on connectors: impedance consistency on high-speed paths, contact stability under vibration and thermal cycling, and reliable RF docking. CPT covers BTB, coax and spring contacts in one place.
The connector set inside a LiDAR
1) Board-to-board: 0.4mm high-pin B118 (10–100 pins) links the main controller to the laser transmit/receive board. For 15mm stacks, 0.8mm BB0098 with 60 pins. 2) RF coaxial: C03 (1.2×1.2×0.4mm, DC–6GHz) or C01 (2.0×2.0×0.6mm, DC–8GHz) between antenna and RF front end. 3) Spring contacts for chassis grounding, shield contact and test points.
Three mechanical and environmental traps
Vibration: roof-mounted and robot-mounted units need retention and anti-release features; re-measure contact resistance after random vibration. Thermal cycling: different expansion between the optical window and the housing means the stack height needs margin. Impedance: at 100 pins on 0.4mm, ground pin placement defines the return path, so fix the ground map before routing.
From sample to volume
Datasheet PDF, 3D STEP and 2D drawings are available for interference checks; we support insertion-force, thermal-cycling and vibration validation; volume production is scheduled per project with tape and reel for SMT.

FAQ
Which BTB series suits LiDAR?
0.4mm B118 between controller and TX/RX boards, sized by channel count; 0.8mm BB0098 where the stack exceeds 10mm.
Which RF connectors are used?
C03 (1.2×1.2×0.4mm, DC–6GHz) or C01 (2.0×2.0×0.6mm, DC–8GHz), both 50Ω micro coaxial sockets with Japanese equivalents.
How should vibration be validated?
Establish an insertion-force baseline, run the vehicle random vibration profile, then re-measure contact resistance and inspect for intermittent opens.
Do you provide 3D models?
Yes, STEP and 2D drawings for B118, BB0098, C03 and C01.
