[6.5-10' (2-3 m)] This transmitter is a replacement. The original lasted three years until rain got into it. It is located around 200 feet from our house. There is a forest with thick bushes between the transmitter and receiver. It is not visible from the house even in winter. It works perfectly as did the original. Shipping and delivery happened as promised by B&H. The whole Optex system has worked great.

[12 VDC @ 30 mA] I have used these for years. They always work great, and the batteries last many years of continuous duty.
Last month alone, in the early morning, a guy broke into my SuperDuty and tried to steal it. I knew about it right away and chased him off with a shotgun BEFORE he got it. Since the cops will not do anything about him, I had to. He was the same guy who stole my neighbor's SuperDuty the week before. I know this because of everyone's surveillance cameras plainly shows the guy at work in our neighborhood. My neighbor is out his expensive truck and I am not, thanks to these little guys.

[12 VDC @ 30 mA] I have had these for probably 15 years, and, in today's world, I purchased more. There are three different sounds/channels. Each channel can monitor 3 sensors. One zone monitors my garage, one zone monitors my boat, and one channel monitors my parking. The parking alarm went off last month and I caught a guy in my F350 trying to steal it. The cops wouldn't come out just for that, so I chased the guy off with a shotgun. He did NOT get the truck. These saved me a ton of money just on that incident. Had not been alerted, I would have lost my truck. The same guy got my neighbor's F350 the week before. Security footage was available for both incidents.
I just changed a battery the other day. the old one was installed 6/2018. Like I said, these are great.
The only improvement I would like to see would be a Zone 1 or Zone 3 annunciator instead of the chimes. It took me a minute to wake up enough to figure out which zone the chime represented when the guy was in my truck. Had I been down there quicker I probably would have had a bloody perp for the cops to haul away. They probably would have come out for that.

[6.5-10' (2-3 m)] We recently ordered more Optex Photelectric Detectors.  These devices have protected our facility for a number of years now .... never the slightest problem.  Very high quality product.

[90°] It works very well, detecting people

[0.5 lb] This works well and is easy and flexible for setup and installation.

[6.5-10' (2-3 m)] The product does what it is intended to do. It works perfectly, notifying us of customers entering or exiting the business. It's use is outside so it holds up to the elements. It's reasonably priced. You won't miss any customers entering your lot or your store if you put one of these to use.

[6.5-10' (2-3 m)] Quick to ship. Description accurate

[12 VDC @ 30 mA] Very good product and a good and fast service.

[0.5 lb] Ordered this product as a replacement for old failed ones. B&H had a better price than the factory and I received them in three days. They are installed and working as required. Thanks for the prompt and courteous service from B&H.
