Intrinsically-Safe Wireless Keyboards Reduce Costs

The BT-87-TP-IS and DW-5K-IS intrinsically safe (IS) wireless keyboards carry Factory Mutual approval for use in Class I, II, and III, Division 1, Groups C, D, E, F and G locations. According to the company, the wireless IS keyboards are as safe as wired IS products but cost 35% because they do not require barriers. The DW-5K-IS requires three AA batteries and a USB dongle isolated from the hazardous location. It features an integrated HulaPoint II pointing device and measures 14.97” x 6.61” x 1.91”. The BT-87-TP-IS is a Bluetooth-compatible, submersible keyboard that does not require a USB dongle if the host computer is also Bluetooth-compatible. It needs two AA batteries, features an integrated touchpad, and measures 12.01” x 7.75” x 2.03”. Both keyboards have a 30’ RF range, are built with a sealed, industrial silicone rubber keypad and a rugged ABS polycarbonate case, and each meets NEMA 4X specifications. IKEY INC., Austin, TX.
