ZKTeco MB20 Metal Enclosure with Lock & Acrylic Front

Description

A precision-machining unit in Faridabad runs five CNCs through a single shop floor. The ZKTeco MB20 biometric attendance machine at the shift-in door sees swarf settle in the keypad within a week of any deep clean. Mist coolant drifts into the air, hands carry trace oil from the chuck, and the screen has a permanent thumb-print mosaic by Wednesday. The MB20 still reads, but the supervisor has stopped trusting it and started running a paper backup. This lockable metal enclosure is what gets the paper backup retired.

Why a machining shop is brutal on a face terminal

It’s not the metal swarf alone — it’s the oil mist riding on the air, the fingerprint-sensor grime that won’t wipe clean, and the keypad slowly seizing as fine particles work their way into the button contours. A bare MB20 lasts maybe eighteen months in that environment before HR starts complaining about reads. A metal cover with a sealed acrylic front keeps the operating environment outside the terminal — the device sees a clean atmosphere even when the shop doesn’t.

The build, in plain language

Cold-rolled mild steel, single-piece chassis, powder-coated matte black. The acrylic front is optical-grade, clear over the MB20 screen and fingerprint sensor. A cam-style lock with two keys per unit secures the front. Powder-coated finish — wipe it down with a workshop rag and it looks new. Made in India by AmpleTrails.

Dimensions designed, not guessed

Cut for the ZKTeco MB20 chassis. Outline, screen window, fingerprint platen and rear port reliefs are at exact factory positions. The acrylic front sits flush against the device — no gaps for mist or fine particles to drift through.

Through power cuts, no missed punches

The Mini UPS bay sits below the device cradle. A 12V Mini UPS keeps the MB20 logging through every power dip — and in a shop running large motors, dips happen at every machine start. With Mini UPS continuity the muster matches the actual shop hours, no discrepancies for the production manager to reconcile.

Mounting

Four rear-plate slots accept 8mm rawl plugs for a plastered brick shop wall. Mount the metal enclosure above operator-shoulder height so swarf-laden gloves can’t reach the lock easily. The flat base supports counter mounting at the foreman’s desk.

What buyers usually ask before ordering

Will this metal enclosure fit my ZKTeco MB20 exactly?
Yes — cut for the MB20 chassis. Screen, fingerprint platen and ports are at their correct positions.

Is the ZKTeco MB20 included?
No — listing covers the metal enclosure only. The MB20 and Mini UPS are sold separately.

How does the cover handle coolant mist?
Acrylic front and powder-coated steel both wipe clean of typical machining mist. Don’t position directly over a coolant trough.

Will the fingerprint sensor read through swarf-dusted hands?
That’s a device-side limitation — the metal enclosure has a dedicated cut-out for the fingerprint platen so the sensor works at full sensitivity. Hand hygiene is on the operator.

Multi-shop orders — can we standardise across plants?
Yes. We fabricate in-house in India; finish and dimensions are consistent across orders.
