DIN 43650B Connector

DIN 43650B Connector

Other names for DIN 43650 connectors include MPM or sugarcube connectors. These solenoid valve connectors come in three versions: Form A, Form B or Form C. They have met various overvoltage protection requirements and are made to function within certain voltage limits. Solenoid Coil Connector is used extensively to provide electrical connection in a wide range of applications. The most common application for Solenoid Coil connector is in conjunction with pneumatic, hydraulic or electromagnetic devices, including solenoid valves. Other applications include, for example, pressure transducers, proximity switches, level sensors, limit switches and low energy motors.

GASKETS

There are three gasket options available for the DIN connectors: NBR Profile, NBR Flat or EPDM Flat. Each of the different gaskets will has different characteristics, mainly based on the material from which they are made. NBR rubber is also known as nitrile rubber. NBR is an oil resistant material, which includes both mineral and vegetable oil. EPDM rubber does not have much resilience against oils, but it does stand up well to ozone, heat and weather. Both materials are satisfactory against basic diluted acids and alkalines. Most of the gaskets available are from HTP and Hirschmann. Separate gaskets are also available for most of the male DIN connectors.

THREAD TYPES
DIN 43650 solenoid valve connectors will have different thread types for the cable entry, depending on the form. Form A connectors are currently available in PG 9, PG 11, M16, or 1/2" NPT thread sizes. Form B features PG 9 or 1/2" NPT threads, while Form C connectors are only available with PG 7 thread. M16 is a metric thread type, which globally is the most commonly used type. The number refers to the nominal diameter in millimeters. PG stands for Panzergewinde and refers to German standards. PG has a bigger thread angle but a lower thread depth than metric or NPT. NPT stands for National Pipe Thread and is an American standard. Unlike metric or PG, these threads are tapered, which helps form a seal.

PIN SPACING
Pin spacing refers to the distance between pins #1 and #2. Each form has different pin spacing, and the pin type also changes depending on the form. Form A connectors have "U" shaped pins facing inwards with an 18 mm pin spacing. Form B connectors have 2 different pin spacings: 10mm & 11mm. 11mm connectors will have 3 flat blade contacts and are the industry standard. 10mm connectors will have 1 flat blade and 2 U shaped pins pointing outward. Form C connectors have flat blade pins with 8mm or 9.4mm (industry standard) pin spacing. Diagrams of the pin spacing are pictured at the top of the page to better visualize their design.
