If so, how long and what sensor IC did you use?** A: I hooked up 4 of these to a 200 ft wire and instead of using the resistor I just eliminated the resistor that is supose to go in the circuit. So if this is what your using it for distance of the wire just don't use the resistor . I hope that's help you **Q: Are they 433mhz sensors?** A: I looked at my package and checked the actual parts and dont see any rating. I had previously purchased a generic button from the hardware store that worked well on a window that the sensor had gotten damaged and it worked fine- so in fact never realized that mhz mattered. the ones i purchased recently work fine - i have one on my door . as replacement or i personally believe even for 1st installation of a hard wired system these will work. I looked at my old sensor that the alarm co had installed and it was also quite generic looking. sorry i dont have an exact answer for you. i dont have any way to test mine .. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works like a charm *by V***Y on December 30, 2020* They work great. Small profile is easy to install in tight areas, but for areas where you need to drill at an angle a larger sensor would be easier because you'd be able to drill a 3/8" wire chase at an angle more cleanly through a 3/4" sensor hole. the 3/8" sensors are great, but you have to take care to drill correctly or you'll have to repair over-sized holes with caulk or putty. ### ⭐⭐⭐⭐⭐ Works great *by M***S on August 21, 2021* Been installing wired alarm panels in rentals. Works great. Renters to hard on stuff that requires battery maintenance or is easy to touch. These are somewhat out of sight so my "handy" renters typically don't mess with them ### ⭐⭐⭐⭐ As advertised. *by F***K on June 6, 2022* Simple install, other than a couple of wires breaking below the window seals.......Not their fault...Seems as advertised --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/88717376-10pcs-rc-33-nc-recessed-wired-security-window-door-contact](https://www.desertcart.sk/products/88717376-10pcs-rc-33-nc-recessed-wired-security-window-door-contact) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-09*
