Operating on 100-240VAC with a 2-wire normally closed output, it offers a precise 2mm sensing distance and flush mount installation. Rated IP67, it withstands harsh environments from -25°C to 70°C, making it a durable and reliable choice for metal detection and automation control. ## Description Standard sensing target : 12×12×1mm(iron) Current specification: Current consumption: Max. 10mAResponse frequency: 20HzMaterial: Brass(nickel plated)Cable Standard/material: Standard cableProtection structure: IP67Approval: CEEnvironment_Ambient temperature: -25 to 70℃, storage: -30 to 80℃Environment_Ambient humidity: 35 to 95% RH, storage: 35 to 95% RHHysteresis(distance): Max. 10% of sensing distanceResidual voltage: Max. 2V Review: Quality inductive sensor - This is a very nicely built proximity sensor. It seems to be excellent quality for an inexpensive unit. The body is all stainless and threaded along its entire length for maximum flexibility in mounting. The wire end seems to be epoxied into a nicely fitting strain relief, and about 3 feet of cable is included for wiring flexibility. The included mounting nuts are about 3mm thick so mounting it flush in a panel would take some additional work to the panel or printing an insert for mounting and using a larger hole. It works as intended, although after more consideration I wound up deciding I should use a DC normally closed sensor for the project I got it for. But this sensor proved to me that it would work for my idea, and I will reuse it in another project where using AC directly is suitable. And based on this sensor and its quality, I'll look to Heschen for more sensors like this. Review: Works as expected. Solid construction. - Works as expected. Note this proximity sensor specifies AC voltage and not DC. Just saying, read the description carefully, speaking from experience, but yes, this works fine when provided with correct inputs. I didn't test it DC and I don't know if applying DC would damage it. ## Features - wire type and power: AC 2-wire type 100-240VAC - Sensing side diameter : M12 - Sensing distance: 2mm - Installation : Shield(flush) - Control output: Normally Closed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08169VWTP | | Battery Description | Battery not included | | Best Sellers Rank | #800,227 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #628 in Inductive Proximity Sensors | | Brand | Heschen | | Compatible Devices | Security System, Smart Home Hub | | Date First Available | June 5, 2020 | | Item Weight | 1.76 ounces | | Item model number | PR12-2AC | | Manufacturer | Heschen Electric | | Maximum Range | 2 Meters | | Mounting Type | Pole Mount | | Operating Temperature | 70 Degrees Celsius | | Package Dimensions | 5 x 2.68 x 0.67 inches | | Power Source | Corded Electric | | UPC | 670534184455 | ## Product Details - **Brand:** Heschen - **Item Weight:** 0.05 Kilograms - **Maximum Range:** 2 Meters - **Mounting Type:** Pole Mount - **Power Source:** Corded Electric ## Images ![Heschen M12 Inductive Proximity Sensor Switch PR12-2AC Cylindrical Type Detector 2mm 100-240VAC 2-Wire NC(Normally Closed) CE - Image 1](https://m.media-amazon.com/images/I/51A91w+b3qL.jpg) ![Heschen M12 Inductive Proximity Sensor Switch PR12-2AC Cylindrical Type Detector 2mm 100-240VAC 2-Wire NC(Normally Closed) CE - Image 2](https://m.media-amazon.com/images/I/51o20dazhbL.jpg) ![Heschen M12 Inductive Proximity Sensor Switch PR12-2AC Cylindrical Type Detector 2mm 100-240VAC 2-Wire NC(Normally Closed) CE - Image 3](https://m.media-amazon.com/images/I/51QY1tgTSML.jpg) ![Heschen M12 Inductive Proximity Sensor Switch PR12-2AC Cylindrical Type Detector 2mm 100-240VAC 2-Wire NC(Normally Closed) CE - Image 4](https://m.media-amazon.com/images/I/61ARptph3zL.jpg) ![Heschen M12 Inductive Proximity Sensor Switch PR12-2AC Cylindrical Type Detector 2mm 100-240VAC 2-Wire NC(Normally Closed) CE - Image 5](https://m.media-amazon.com/images/I/61ZD8JiBbZL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality inductive sensor *by C***. on November 22, 2025* This is a very nicely built proximity sensor.
