explore four access control solutions to make your work easier

Every installer knows the feeling: you roll up to a job, crack open the truck, and realize the one part you need is the one part you don’t have. The right truck stock is the difference between wrapping a call in an hour and burning half a day chasing components.

At EMX Industries, we design our photoeyes, vehicle detectors, and access control sensors to be flexible, simple, and adaptable — so a single SKU can cover scenarios that used to demand three. Below are four updated solutions worth keeping on your service truck to make every install faster, cleaner, and more reliable for the customer.


1. IRB-RET2 & IRB-MON2 Photoeyes

Best for: entrapment protection on gates, doors, and barriers.

The newly upgraded IRB-RET2 retroreflective photoeye and IRB-MON2 thru-beam photoeye handle a wide range of UL 325 entrapment-protection applications. Carry both, and you’re ready for tight retrofit jobs and long-throw installs alike.

IRB-RET2 — at a glance

  • 60 ft. operating range · retroreflective (single-unit + reflector)
  • Six monitoring interfaces: NC, two-wire pulse (2 & 3 freq), four-wire pulse (2 & 3 freq), and 10K resistive termination
  • Selectable Stealth Mode — LEDs turn off after 30 seconds with no obstruction, deterring vandalism
  • Compact enclosure, integrated sensor hood, easy-adjust ball & socket bracket

IRB-MON2 — at a glance

  • 115 ft. operating range · thru-beam (separate transmitter + receiver)
  • Four monitoring interfaces · removable terminal block for cleaner wiring
  • Integrated protective hoods + removable lens sun shield for indoor/outdoor service
  • UL 325-2018 compliant and compatible with most monitored operators & non-monitored legacy products

2. WEL-200 Wireless Edge Link

Best for: safety-edge installs where running wire is a headache.

Safety edges are essential — but wiring them adds time, cost, and a long-term maintenance tail. The WEL-200 Wireless Edge Link kit eliminates the wiring between safety edges and the operator while keeping you UL 325-2018 compliant. One receiver pairs with up to four transmitters, so a single kit can cover multiple edges without extra runs.

What’s new: the latest revision adds a radio signal quality display — a one-digit readout (0–9) on the receiver that tells you connection strength on the spot. No more guessing during alignment.

WEL-200 — at a glance

  • 200 ft. line-of-sight range between transmitter and receiver
  • Compatible with NC, 10K, and pulse-monitored outputs · works with both 8.2K and 10K monitored safety edges
  • Receiver supports up to 4 transmitters with separate open/close relay and pulse outputs
  • 2-year battery life on two AA lithium cells per transmitter
  • Rugged, watertight NEMA 4X enclosure

3. MVP D-TEK Multi-Voltage Loop Detector

Best for: any service call where you don’t know the operator’s voltage in advance.

You’ve been there: you show up, the loop’s ready, but your detector doesn’t match the available power supply. The MVP D-TEK multi-voltage loop detector ends that problem. Stock one detector instead of three — it works on virtually any supply you’ll encounter in the field.

MVP D-TEK — at a glance

  • Universal voltage: 12 to 220 VAC/DC
  • Operates in both fail-safe and fail-secure modes
  • 10 sensitivity settings for distinct detection needs
  • Built-in loop conditioner, loop isolation transformer, loop diagnostics, and frequency counter
  • Two relays (presence & pulse, or presence) with gold-plated contacts
  • Extruded anodized aluminum RF-shield housing · enhanced lightning/surge immunity

4. VMD202 Vehicle Motion Detector

Best for: free-exit applications — especially solar-powered installs.

Free-exit jobs usually mean cutting a fresh loop or, worse, digging up an old one to retune the probe. The VMD202 Vehicle Motion Detector skips all of that. Pair it with the optional VMD202-R sensitivity remote and you can adjust settings while the probe stays buried — settings are saved in non-volatile memory, so once it’s dialed in, the remote can move on to the next job.

VMD202 — at a glance

  • Ultra-low 70 µA standby current (25 mA activated) — great for solar applications
  • Wide power input: 12–39 VDC or 12–27 VAC
  • Watertight, direct-burial probe and cable assembly
  • Non-volatile memory keeps settings through power loss
  • 10 sensitivity settings via the optional VMD202-R remote
  • Single-piece probe with 50 ft. lead (100 ft. version also available)

Stock Smarter. Install Faster.

EMX has been designing access control, safety, and vehicle detection solutions for decades — and every product on this list is built around the same idea: fewer trips back to the shop, fewer callbacks, fewer compatibility surprises in the field.
