STS-K002L is Contacta’s surface-mounted window intercom for quieter counters and booths. Separate customer-side speaker and microphone units work with an open-duplex amplifier, staff microphone/loudspeaker and counter hearing loop. It is not a network switch.

STS-K009-IP-L-B is Contacta’s entry intercom kit with an IP55 surface-mounted customer call unit, open-duplex speech amplifier, staff unit and hearing loop. The front call button alerts staff while the communication channel remains hands-free.

IR-RX2 is Contacta’s portable infrared receiver for assistive listening, supporting the manufacturer’s 2.3 MHz and 2.8 MHz transmitters. It uses rechargeable batteries and requires headphones or an assistive neck loop; it is not an Ethernet switch.

IR-RX2-DC5 is a five-position charging base for Contacta portable listening receivers, including IR-RX2. It is a charger accessory, not a network switch. Expansion to twenty receivers requires four bases and the approved higher-current power supply.

RF-DC6-865/915 is Contacta’s six-position drop-in charger and programming station for RF-RX1 receivers and RF-TX1 transmitters. Choose the regional 865 MHz or 915 MHz version to match the devices; the slash does not identify a universal dual-band unit.

Contacta STS-SJB is the 3.5 mm break-out box for a window intercom staff-side headset connection. The RJ11 version is a different product code, STS-SJB-RJ.

STS-K058 is a Contacta window intercom system with a bent, vandal-resistant customer microphone mounted to the screen, a staff unit and a counter hearing-loop facility.

V34a PRO is Contacta's constant-current, dual-output driver for phased-array hearing loops in large venues. It supports network-based setup and status monitoring, not general-purpose network routing.
Contacta buyers should validate exact manufacturer part number, interfaces, power and compatible accessories, condition, warranty, lead time and support status. Use the active catalog below to compare exact part numbers and open each product page for specification, condition, price and official-source details.
Start with the exact manufacturer part number rather than the marketing family name. Then compare the technical configuration, included licenses and accessories, product condition, warranty responsibility, lead time and destination-specific requirements. For replacements, validate interoperability with the installed software, optics, power and management platform.
YYST Global product pages provide model-level specifications and official manufacturer references where available. Procurement teams can use these pages to prepare a bill of materials and then request confirmation of quantity, serial-number availability, shipping and acceptance terms.
