Cable Harness Contact Probe Pin CHL137 for the Tests of Automotive Industry
Harness probes are mainly used directly or for the tests of automotive industry. Parts of them are also applied to communication electronics, medical equipment, equipment automation, etc. The standard and requirements for them are high compared with other test probes. Harness probes can be divided into screw-thread harness probes, harness switch probes, non-screw-thread harness probes, position-limited harness probes and high-current harness probes, etc.
The CHL137 harness probe we will introduce here is 1.37 mm in diameter and 26.7 mm in total length. Its barrel is made of brass plated with gold and nickel. The plunger is made of gold-plated beryllium copper, which is softer but less magnetic than the alternative SK4. The spring inside is made of music wire plated with gold and nickel.
This probe can withstand up to the current 3 Amps. Its typical maximum contact resistance is 100 milliohms. It is suggested the plunger be pressed at a distance of 2.8 mm at most when this probe works, although the plunger can move as far as 4.2 mm. Otherwise, the spring inside the barrel will probably be damaged under constant pressure. When the plunger is pressed at a distance of 2.8 mm, its loaded force is about 100 gf, namely 3.5 ounces or so. Furthermore, the force fluctuates in a range due to the tolerance.
