F-type 75-Ohm radio-frequency connectors are used for connecting Series 59, Series 6, and Series 11 coaxial cable to video, CATV, and security cameras. The most widely used connector for residential cable service. F-type connectors do not have center pins. In-stead, they use the solid center conductor of the cable as a center pin. For this reason, F-type connectors cannot be used with cables that have a stranded center conductor. Usage of the cable center conductor instead of a pin makes F-type comparatively inexpensive.F-Type feed-thru modules are compatible with all Signamax keystone panels, faceplates and surface-mount boxes. Connectors are 75 Ohm and rated for 1- or 3-GHz performance.Product Features: 1 and 3 GHz versions available 75 Ohm Bronze shell and terminal 3/8-32 thread Compatible with all Signamax keystone panels, faceplates and surface-mount boxes Easy connection in the field Download Product Spec Sheet: SignaMax F-Type Keystone Connector Modules Spec Sheet (PDF) Specifications:TRANSMISSION PERFORMANCE: CMK-F: up to 1 MHz, CMK-F3: up to 3 MHzTRANSMISSION MEDIA: Coaxial, 75 Ohm (RG6/U, RG-58/U)WIRE GAUGE: 18-22 AWG (0.64-1.07 mm) solidFrequency range: CMK-F: 1 GHz DC, CMK-F3: 3 GHz DCImpedance: 75 OhmInsertion loss: < 0.3 dB at 1 GHz, CMK-F: < 0.3 dB, CMK-F3: < 0.2 dBReturn loss: CMK-F3: > 30 dBContact resistance: < 4 mOhm Insulation resistance: min 500 MOhm at 100 Vdc Inductance: min 500 nH Capacitance: min 2 x 1.5 nF Operational voltage: 250 Vdc Test voltage: 750 Vdc for 1 min Peak voltage rating: 500 V Dielectric withstanding voltage: 1,500 Vrms Feed-through current: max 10 ACONSTRUCTION: Housing: high impact thermoplastic, UL94V-0 fire-retardant, Shell: brass, nickel platedSeizing pin: CMK-F: bronze alloy, tin-plated, CMK-F3: 360-degree beryllium bronze, gold-platedInsulation: CMK-F: low-density polyethylene (LDPE), CMK-F3: nylonNut: iron plated with nickel over copperMECHANICAL: Mating cycles: min 500Holding force: > 160 g (initial), > 120 g (after insertion)Interface dimensions: similar to MIL-C-39012 Housing shall support 2.2 kg-force minimum applied from either directionFOOTPRINT: Standard keystone footprintMOUNTING DIMENSIONS: D 30.0 mm H 19.7 mm W 16.5 mm, D 1.18 in H 0.77 in W 0.65 inENVIRONMENTAL CONDITIONS: Storage: -40 †C-+70 †C (-40 †F-+158 †F), Operation: -10 †C-+60 †C (+14 †F-+140 †F), RH (operation): max non-condensing 93 % Vibration, shock, and temperature cycling in accordance with MIL-STD-1344COMPLIANCE: ANSI/SCTE 02, IEC 60169-24, UL 94V-0APPLICATIONS: Over-the-air terrestrial television, cable television, satellite television, cable modemsWARRANTY: 5-year limited component warranty
