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.
| Type | Best for | Key spec |
|---|---|---|
| Panel counter | Machine front-plate readout | Up to 6 digits, contact/pulse input |
| Handheld tachometer | Quick RPM checks | Non-contact, up to 99,999 RPM |
| DIN-mount timer/counter | Control panels | Programmable setpoints, relay output |
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.
