Counters & Tachometers Supplier South Africa - Local Stock, Industrial & Lab Units

Why choose locally stocked counters and tachometers

When uptime matters - on the shop floor, in student labs or for prototype testing - having counters and tachometers available locally removes long waits and uncertainty. Communica stocks a broad selection of panel counters, handheld tacho meters, photoelectric RPM sensors and DIN-mount timers so you can complete projects, run QA checks or equip a lab without import delays. Our Samrand warehouse plus branches in Pretoria and Cape Town mean faster lead times and branch pickup if you need a unit today.

Practical value: what to expect

We focus on parts and kits that technicians and makers actually use: compact panel counters for machine status, non-contact tachometers for shaft RPM checks, and programmable counters for event tracking. Each product listing notes key specs - input type (pulse/contact/optical), counting speed, display digits, power supply and mounting - so you can match performance to the application. For an overview of related product categories, see Collections and our All Products index to compare options side-by-side.

Specification callouts that matter

When choosing a counter or tachometer, prioritise these specs: input type (NPN/PNP/contact/phototach), maximum pulse frequency (Hz or kHz), display resolution (digits), power supply tolerance, mounting style and protection class. Below is a compact comparison to help shortlist quickly.

Compatibility and accessories

Match the counter input to your sensor: use optical/IR sensors for non-contact speed, hall-effect or proximity sensors for ferrous shafts, or simple mechanical switches for low-speed event counting. We stock compatible sensors, meter mounting kits and wiring accessories in our Shop by Brand and component collections to create ready-to-install bundles.

Local logistics and account facilities

Need a VAT invoice for procurement or tertiary projects? We provide account quotes and documentation for institutional purchases and student lab buys. Check live branch availability or collect from Samrand - use our branch hours and locations page to plan pickup and avoid delay: Branches & Trading Hours.

Spec-driven buying: compatibility checks and common examples

Practical examples help pick the right unit. For a conveyor counter that tracks items at 30 items/min with a single proximity switch, a 4-digit panel counter with contact debounce and a minimum pulse width of 5 ms is sufficient. For high-speed spindle checks at 12,000 RPM use a non-contact optical tachometer rated above 200 Hz pulse frequency. If you need help matching specs, request a quote and our technical team will confirm compatibility with your sensor and control system.

Accessory bundles we commonly recommend

• Panel counter + DIN rail power supply + gasketed bezel for washdown environments
• Handheld tachometer + reflective tape + spare batteries
• DIN-mounted programmable counter + relay output module + connector harness

Bundling saves assembly time and reduces risk of mismatched connectors. View compatible items under the relevant collections in our store to build a bundle quickly: Shop Collections.

Handling objections: stock, lead times and support

Worried about availability? We keep a mix of fast-moving counters and tachometers in Samrand and replenish popular lines from multiple brands to reduce lead times. If a specific model is out of stock we offer alternatives with clear spec comparisons so you can decide quickly. Need installation help?
