The BNS33-12Z-2187-2M is a Coded Magnetic Switch with quick-connect terminals, 1NO/2NC contacts and 2m cable. The BNS33 series coded-magnet sensors are designed for use as a safety interlock switch on movable machine guards/articulating robot arms. Each sensor set consists of a multiple reed switch unit and a coded-magnet actuator. The reed switches, wired in series, will only close in the presence of their matched magnetic field array. Their tamper-resistant design prevents bypassing with a simple magnet or improperly coded magnetic field. In addition, the BNS module features an optional built-in LED display of switch status and a 1m long prewired pigtail to assure sealing integrity. The sealed compact BNS33 is ideal for use on movable machine guards in hostile environments or where space is limited.
- Compact size
- Sealed for submersibility - assures long-term reliability in the most hostile environments
- Rugged, corrosion-resistant housing - Tolerates most industrial environments
- With LED status indicator and individual contact outlet
- Shock and vibration tolerant - Designed to withstand mechanical abuse

Reliable and lasts forever Best budget option
Style: Combo, Color: Black, Size: 1 Pack, Style: Combo, Color: Black, Size: 1 Pack
I had this same model a long time ago and it lasted forever, I only had to get a new one because I lost the USB receiver, so I know for a fact they are very durable. For the price, you can't beat the compatibility you just plug it in and it works instantly. The appearance is very simple, it's not the most attractive or pretty keyboard since it has no lighting or fancy features, but it's built to last. The noise level is fine for a membrane keyboard, not too loud. In terms of ergonomics, it feels comfortable enough for daily work and the color is just the standard black that goes with everything. The best part is the battery life, it lasts months without needing a change.

Exceptional
Size: 22, Size: 22
Great quality and price. Monitors are exceptional. Would buy again without question. Screens are quite resilient, great picture. I bought three and use them in a multi Monitor setup for my work laptop, I needed something to view wireing diagrams and scan tool information qt the same time. If your a Service Technician looking for a multi Monitor set up would strongly recommend this Monitor.

Great product and great price
Size: 22
I think the negative thing I can highlight is the pixel dentist isn’t that high so it doesn’t look as crisp but this is a great budget option when you are in a hurry (like me) or simply need a screen that does its job. I use it for home office and it’s more than enough.

Works for what u pay
Size: 22
Only reason it’s not a 5star is bc I’m picky it doesn’t have any speakers first of all so don’t go thinking there’s sound refresh rate is what you would think for this price it runs games super well and has decent quality easy to use and pretty bright as well it’s not a curved monitor so the viewing is pretty normal
