Product details

The GTB6-P4212 is a G6-series miniature photoelectric proximity sensor with a 250 mm sensing range and a 625 µs response time — fast enough to catch parts on a moderate-speed conveyor or detect presence in a pick-and-place cell without missing targets. The PNP output switches 100 mA, so it drives a standard PLC input directly; no interposing relay needed. Light-ON / Dark-ON switching is selectable, which means one part covers both diffuse and retro-reflective logic without a separate variant. The 12 mm wide housing fits tight DIN-rail or machine-mount slots, and the M8 4-pin connector simplifies field replacement — unplug the old sensor, plug in the new one, no rewiring.

Deployment context

Rated IP67, so the sensor body and optics handle washdown and dust — suitable for packaging lines, bottling plants, or any area where a hose-down cleaning cycle is routine. The 10–30 VDC supply range covers standard 24 VDC control power with headroom for brownout conditions.

Frequently asked questions

What is the closest functional second-source for GTB6-P4212?

The GTB6-P4231 is the closest peer in the G6 family: same 12 mm width, same M8 4-pin connector, same PNP output and 100 mA load rating. The main difference is the P4231 has a longer 400 mm sensing range and a 1.2 ms response time (slower than the P4212's 625 µs). If your application needs the faster response, the P4212 is the right call; if range matters more, the P4231 is a direct swap on the same mounting footprint.

Where can I buy GTB6-P4212?

The GTB6-P4212 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will GTB6-P4212 drop into a panel specified around GTB6-P4231 without rewiring?

Yes — both sensors share the same 12 mm width, M8 4-pin connector, PNP output, and 10–30 VDC supply. The wiring pinout is identical, so the P4212 replaces the P4231 without changing the cable or terminal assignment. The only functional difference is the sensing range (250 mm vs 400 mm) and response time (625 µs vs 1.2 ms).
