Why choose Communica for counters & tachometers
When your project or production line depends on accurate RPM or pulse counting, availability and correct spec selection matter more than the lowest sticker price. Communica offers deep local stock, fast branch pickup from Samrand, Pretoria or Cape Town, and pro support to match a counter or tachometer to your exact application. Shop Now with confidence, compare specs, or Request a Quote tailored to bulk procurement.
Quick benefits
- Local availability reduces lead time and freight cost for students, makers and technicians.
- Range spans panel meters, handheld tachometers, encoder counters and programmable digital counters.
- Business-friendly invoicing, VAT-compliant receipts and account quoting for procurement teams.
Types, common specs and where to use them
Selecting the right device starts with the signal type (contact, hall/optical sensor, encoder, or analog frequency), rpm range, display resolution and environmental rating. Below is a compact comparison to orient decisions before you check current stock.
| Type | Typical Inputs | Best for | Key spec callouts |
|---|---|---|---|
| Panel counter | Pulse, switch | Control panels, test rigs | Counting speed, reset function, mounting cutout |
| Handheld tachometer | Optical/tach pick-up | Field RPM checks | Non-contact range, resolution, memory |
| Encoder counter | Quadrature encoder | Motion feedback, positioning | Lines per revolution, indexing, debounce |
| Frequency-to-voltage/tach modules | Analog/frequency | Signal conditioning | Input impedance, bandwidth, output scaling |
Compatibility guidance
Confirm sensor or encoder electrical levels (TTL, 5V, 24V), pulse shape, and required debounce or input filtering. Many panel counters are designed for 12-24 VDC logic; others accept contact closures. When in doubt, bring a sample to your nearest branch for a quick compatibility check - view branch details at Branches & Trading Hours.
Specification callouts to request
- Maximum pulse frequency (Hz or kHz) and minimum pulse width
- Input voltage range and input type (sinking/source, opto-isolated)
- Display digits, update rate and memory/totaliser features
- Mounting form factor (panel cutout, DIN rail, handheld)
