Test systems and fixtures
CZ4 combines contact modules in one frame, DMK closes with a cam and POGO presses spring pins onto pads; all three serve test and measurement equipment.
Connectors for Test and Measurement Equipment
Test systems and fixtures are mated many times a day and must keep contact resistance stable across thousands of cycles.
CZ4 modular connectors reach 15,000 cycles, DMK zero-insertion-force connectors and POGO spring pins 10,000; HJ30J high-speed Micro-D and J30JZ twist-pin connectors handle dense signal interfaces.

Where they are used
Dense instrument and data interfaces
HJ30J carries differential signals in a Micro-D format; J30JZ and J29 give compact twist-pin connections with cable and PCB terminations.
Portable and laboratory instruments
PBH serves portable and laboratory equipment with straight push-pull mating; Y27 serves portable instruments and automated test equipment with a latching push-pull.
What the connectors must handle
Mating life
CZ4 reaches 15,000 cycles with its quick-lock and 5,000 threaded; DMK and POGO reach 10,000; J30JZ up to 20,000.
Power and signal in one frame
CZ4 modules hold 2, 4, 5, 10 or 45 contacts from 1 A to 50 A; the 2-contact high-voltage module withstands 6000 VAC.
High pin counts, low insertion force
DMK covers 60, 96, 156 and 260 contacts on a 2.54 mm grid. A cam closes the contacts after the halves are brought together.
Differential signals
HJ30J is specified at 100 ± 15 Ω, with 1.65 Gbps over cable and 3.125 Gbps PCB to PCB.
Spring pins
POGO pins have a 2.54 mm pitch and 0.8 mm stroke in single- or double-row layouts, and press on flat target pads at 1 A.
Temperature and handling
PBH1 runs from −60 to +150 °C at 5 A per contact; PBH2 and PBH3 run from −60 to +100 °C.

How to choose
Define the circuits
List power and signal positions with current and working voltage; for differential links, mark the pairs and grounds.
Choose the handling method
Give the cycle count and how the fixture is loaded: quick-lock, cam, spring pins on pads or push-pull.
Lay out the termination
Send the PCB drawing or cable pin-out. J30JZ offers pre-wired, solder-cup, straight and right-angle PCB terminations; DMK offers crimp contacts or PCB tails; POGO has surface-mount tails.
Send the full interface
Send the model or drawing with locking hardware and contact layout, and we will review your project.
