Environmental protection and environmental protection, rocker encoder with switch and without switch, how to determine true dual and false double encoder?
Parts are: 1, the encoder resistors, push the handle, brush, shell.
2, encoder, environmental protection and environmental protection to distinguish: mainly refers to the resistance itself material is in line with ROSH environmental protection requirements.
3, single league: namely for the common single product, go to the foot 1 or 3 foot end all have resistance, residual resistance on both ends (
Which is 1 ~ 2 feet and 2 ~ 3 feet)
For 1, 2, 3, 4 feet, single to be switch, namely resistors end with insulation layer, when VR to the end, the brush moves with the insulating layer on the disconnect (
Part 5, double without switch, a total of 1 foot: common dual model, resistors two carbon film resistor body 1 foot linked together, the existing product name for R1001G are double without switch, a total of 1 feet 6, double without switch, a total of 3 feet: namely resistors resistors two carbon film resistor body 3 foot linked together, the existing product name for R1001L are dual switch, a total of 3 feet 7, with switch and without switch to distinguish: products in the end of the push 1 to 3 feet or legs, no resistance to disconnect test (
, with switch and without switch for resistors two kinds of printing, is a kind of insulating layer, the disconnection when the brush is running to the paragraph, the other is not printed, the brush is running to the paragraph, brushes off 8 come into direct contact with the substrate, true dual and false double difference: false double is the same on resistance of two resistors, which share a silver layer (2 feet
At one end up two gilded al)
, false double is the same two resistance resistors, but two resistance body used to separate the two silver layer 2 feet, that is to say, there are two silver layer printing Shanghai electronic 25 years specializing in the production of rocker encoder, advanced and reliable production and testing equipment, production experience and reliable product quality and safety, to find manufacturers will find old rocker encoder - encoder manufacturer
