M172 and M172-i Durable Tag Deployment
The M172 and M172-i Durable Tags are particularly well-suited for hospital asset tracking. The tags can be deployed on
expensive medical equipment so that these valuable assets can be located quickly for use in life-saving and other
situations.
M172-i Durable Tag deployed on a “patient vitals” machine.
M172-I Durable Tags deployed on a wheelchair and underneath a patient bed.
Cleaning M172 Durable Asset Tags
The M172 Durable Asset Tag enclosure is injection molded from polycarbonate (PC) thermoplastic polymers.
Polycarbonate is a very durable material, with high impact-resistance and can undergo large plastic deformations without
cracking or breaking. This polymer is highly transparent to visible light and has better light transmission characteristics
better than many kinds of glass.
Tag Enclosure Sealing
The tag enclosure is sealed using an ultrasonic welding process. If the tag is subjected to sustained loads under harsh or
hostile environmental conditions, the enclosure may show signs of environmental stress cracking. The propagation of
cracks over time can result in cosmetic and functional defects (e.g., broken seal, water penetration, electronic failure).
Any product containing plastic material is susceptible to time-dependent viscoelastic cracking. Exposure to certain
chemicals [including ammonia, highly concentrated alcohol solutions (e.g., 100% isopropyl alcohol) and oil-based
products (e.g., mineral oil, vegetable oil)] can accelerate the stress cracking process. Customers are encouraged to
evaluate product performance and fitness for use in their operating environment before deploying large populations of
tags. RF Code, Inc. warrants all tags to be free from defects in materials and workmanship for a period of one (1) year.
