Hengstler’s 634-635 series miniature totalising electromechanical counters are available to order with either high immunity against magnetic interference (type 634), or with high impact resistance (type 635). A single line 6 or 7 digit display (mechanical figure wheel) can be supplied with four mounting options, these are panel mount or direct PCB mount, please see technical information for display orientation and pin connectivity. Supply voltages are: 5V, 12V or 24V DC, connection is via solder pins or wiring posts depending upon the version selected. Types 1 and 3 can be machine-soldered, and if necessary, be washed with no problems. These miniature electromechanical counters are non-scalable, the pulse duty factor is 1:1 therefore no setup or programming is involved. Small mounting dimensions, low power consumption and maintenance free operation (10 million pulses) allow for use where space is restricted. Here we list 6 digit displays, however, a 7 digit display can also be produced (see downloadable data sheets), other variations can also include flying leads and different voltages not shown here, please call us for further information.
