Pet Door Collar with Digital MS-5 Transmitter for Compatible Doors and Indoor or Outdoor Sonic Fences

Keep your dog's compatible pet-access and boundary systems working from one rugged MS-5 digital collar. Its ultrasonic transmitter activates every Power Pet Door model as well as the Sound Barrier indoor fence and Yard Barrier outdoor fence.

Built for an active dog's daily routine, the collar combines stable digital signaling, a fully enclosed transducer, and a dedicated battery system. Choose the included-battery option or add 2, 6, or 12 extra batteries for future changes.

Key Features

• Digital circuitry produces a strong signal and maintains accuracy across temperature ranges, supporting consistent communication as conditions change.
• The extra-rugged construction stands up to canine roughhousing, making the collar practical for energetic dogs and everyday wear.
• A fully enclosed ultrasonic transducer is waterproof and immersible to 6 ft, providing added reassurance during brief accidental immersion.
• The B-3V1A battery lasts about three months, reducing frequent battery changes, while its design protects the circuitry if inserted incorrectly.
• One MS-5 collar powers all Power Pet Door models plus the compatible indoor and outdoor sonic area fences, keeping a multi-device setup straightforward.
