Why choose locally stocked counters and tachometers
For makers, students, technicians and procurement teams in South Africa, access to the right counter or tachometer can speed up commissioning, reduce downtime and keep projects on schedule. Communica stocks a broad range of panel counters, handheld tachometers and DIN-mount pulse counters with immediate availability from our Samrand head office and Cape Town branch, reducing lead times compared to import-only suppliers. Pick up in-branch, get VAT invoices for institutional purchases, or request a quote for bulk orders.
Key buying benefits
- Local stock for faster delivery and branch collection (Samrand, Pretoria CBD and Cape Town).
- Technical advice for selecting pulse ranges, input types and mounting options.
- Account quoting and VAT-compliant documentation for education and business purchases.
Common specifications to consider
Focus on input type (NPN/PNP, dry contact, AC pickup), max input frequency (Hz), display digits, reset method (manual/remote), and supply voltage. Below is a short comparison to help narrow choices quickly.
| Type | Typical Supply | Max Input Frequency | Use Case |
|---|---|---|---|
| Panel counter (digital) | 12-24 VDC | up to 100 kHz | Production counting, batch control |
| Handheld tachometer | Internal battery | N/A (optical/contact) | On-shaft speed checks, maintenance |
| DIN rail pulse counter | 24 VDC | up to 200 kHz | Machine monitoring, PLC input conditioning |
Quick compatibility checklist
Before you order, confirm: sensor output type, whether you need AC or DC pickup, if a display is required, and whether the device needs a remote reset or relay output. If you need help matching a counter to a sensor or PLC, our product range is indexed by category - explore counters in our collections shop by category or browse brands we stock shop by brand.
Specification callouts we routinely recommend
- Select counters with a rated input frequency at least 2x your sensor's peak to avoid missed pulses.
- For noisy environments, choose devices with Schmitt-trigger inputs or add input conditioning (RC filter or opto-isolation).
- Prefer counters that offer both manual and remote reset for flexible operation in lab or production.
