Material: Brass Conductor + PA66 Flame Retardant Housing
Certification: CE, RoHS, UL
Feature: Screw Clamp, Firm Connection, Easy Wiring
Type: Straight Pin / Right Angle Pin
Application: PCB Board, Power Supply, Instrument, Industrial Control
Screw-type PCB terminal block adopts traditional screw clamping structure for stable and firm wire connection. It is made of high conductivity brass terminal and UL94 V0 flame retardant PA66 insulation material.
All products comply with CE, RoHS and TUV safety standards. The screw tightening design provides strong clamping force, not easy to loose, suitable for long-term stable operation in industrial environments.
Available in straight pin and right angle pin versions to meet different PCB layout requirements. Widely used in power supply equipment, instrumentation, PLC and industrial control circuit board wiring.
Screw Type PCB Terminal Block — Straight & Right Angle Pins
The screw-type PCB terminal block is the most proven board-to-wire connection in industrial electronics. A high-conductivity brass screw clamps the conductor with strong, re-tightenable contact force — accepting virtually any wire type and cross-section, tolerating imperfect strips, and giving a connection that can be inspected and re-torqued at any time in the product’s life.
Available in straight pin for standard board layouts and right-angle pin versions where wiring must exit parallel to the PCB inside low-profile enclosures, so the same electrical design fits both open panels and compact housings.
