Product details

Mounting and Termination — What Ships in the Box

The 930-193J-51S: This is a bulkhead-mount jack with a rear-side nut — you feed the connector through the panel from the front, then tighten the nut from behind. The package includes the connector and one lockwasher, so you have the hardware to secure it against vibration in a single order line. The nickel-plated brass body gives a corrosion-resistant ground path, and the silver housing colour is standard for QMA hardware.

Temperature Range and Operating Environment

Rated from -55°C to 100°C, this jack lives comfortably in outdoor telecom cabinets, unheated industrial enclosures, and vehicle-mounted RF decks. The PTFE dielectric doesn't shift permittivity with temperature the way a nylon or polypropylene dielectric would, so the 50 Ohm impedance holds across the band. The 480 V voltage rating is more than adequate for the signal levels typical on a QMA line — the real limit is the power handling at 6 GHz, which drops with frequency per the manufacturer's derating.

Frequently asked questions

What is the impedance of the 930-193J-51S?

The 930-193J-51S is a 50 Ohm QMA jack, rated from DC to 6 GHz. The PTFE dielectric maintains the characteristic impedance across the full frequency range.

What does the package include for the 930-193J-51S?

The package is Bulk and includes 2 pieces: one QMA jack connector and one lockwasher. The lockwasher secures the rear-side nut against vibration in the panel-mount installation.
