Widely applied to signal transmission of electric equipments

Main characteristic

1. Referring to GJB142A-1994 and GJB1308-1991.

2. Plug and socket can exchange with ordinary D series connector.

3. There is a high performance type π or type C filter on each contact element, having good ability of resisting RF interference.

4. The characteristic of each filter can be setted according to user’s needs.

5. The products are whole sealing structure. When filter isn’t added, products are pure sealed connector.

6. Adopting 20# contact elements, all of which are gold plating. They have terminal connection types of welding wire and welding panel. The number of cores has 9, 15, 25, 37, 50.

7. The shell of the products is nickel plating or cadmium plating, resisting corrosion of salt spray.

8. Widely applied to signal transmission of electric equipments such as digital instruments and meters which have requirements for EMC.

Code of mark

      L2           S

D X L1 – G n P B / 2 E - E

D: shell locating rectangular connector

X: code of shell-E, A, B, C, D

L1: L1-type C filtering, L2-type π filtering

G: cadmium plating, no mark for nickel plating

n: number of contact elements-9, 15, 25, 37, 50

P: P-pin, S-jack socket

B: B-straight panel connection, L-bent panel connection, no mark for welding wire type

2: number of filtering contact elements of some frequency band-2 E frequency bands, no mark means all are these frequency bands.

E: frequency band

E: code of filtering capacitor’s type: E-chip capacitor, P-array plate, no mark for tube type capacitor

Note: The shell No. is corresponding with the number of contact element. For example, the number of shell E’s contact element is 9, the number of shell A’s contact element is 15, the number of shell B’s contact element is 25, the number of shell C’s contact element is 37, the number of shell D’s contact element si 50.
