Free samples
Evaluate the latch, sealing and finish on your own equipment before you commit — samples are available free of charge for project review.
TRCONN builds push-pull self-locking circular connectors, waterproof connectors, machine vision connectors and industrial RJ45 solutions for buyers who cannot afford an unstable link. From 2 to 32 pins, IP50 to IP68 sealing and over 5,000 mating cycles, every series is engineered, tested and shipped through one accountable production route.
Why TRCONN
Our advantages.
Four commitments that shape how every TRCONN order is handled.
02
Custom harness
Send a drawing or a pin layout and we build the harness to match — cable type, length, termination and sealing level configured to your equipment.
03
Factory direct
Connectors come straight from the TRCONN production site, so specifications and accountability stay in one place from quotation to shipment.
04
Fast lead time
Standard series are produced and verified in-house, which keeps production lead times short and delivery dates predictable.
Technology network
Four disciplines. One connected system.
One connected system from field signal to production data: push-pull locking that survives vibration and pull-out, sealed connectors for washdown and underwater work, and shielded industrial Ethernet that keeps every device on the line talking.
01
Connector engineering
Shell sizes, pin counts, keying and solder or PCB terminations matched to your equipment, from compact 0B shells to 32-pin multi-signal formats.
02
Sealing & endurance
IP50 to IP68 protection, over 5,000 mating cycles, 10–2000 Hz vibration at 15 G and 100 G mechanical shock across the B, K and T families.
03
Industrial networking
Molded, assembled and waterproof RJ45 versions with positive locking, keeping industrial Ethernet seated on moving machines and noisy drive cabinets.
04
Production & quality control
Controlled assembly, electrical and mechanical testing on every batch, and a 7–15 day prototype route that keeps your development schedule honest.
Industry Application
