knitter-switch, now offers a wide range of switch types with additional patient and equipment safety features for use in medical applications.

A new electronic filter, designed specifically to allow monitored intruder alarm systems to connect to a DSL activated line such as Broadband, is announced by security components specialist Focus EDL.

Tyco's T9C AC coil power relay gives enhanced versatility for applications such as HVAC, power supplies, domestic appliances and measurement and control. The new device compliments the existing T9A series, which is currently only available with a DC coil.

The new 610 and 650 Series four terminal bare element resistors from Ohmite provide ultra low resistance values (to 0.005 ohms) for relatively high current requirements.

Designed to meet the exacting requirements of military specification MIL-R-93, the new P Series moulded precision wirewound resistors from Ohmite offers high stability and low temperature coefficient of resistance (TCR).

With ratings from 90-330 watts, the new range of WFH flat, heatsinkable, wirewound resistors from Ohmite offer cost savings, weight and space savings, plus superior thermal efficiencies over conventional aluminum housed resistors.

The new WH/WN/WL series miniature moulded axial leaded wirewound resistors from Ohmite uses the high purity (96% Alumina) ceramic cores with wire winding which are spot welded by CNC machine tools to ensure total operational consistency throughout.

Specifically designed and developed to absorb more energy than standard film resistors, the new TFS Series from Ohmite is said to be ideal for medical surge protection applications and for the replacement of standard carbon composition resistors.

The new HVC series high voltage chip resistors from Ohmite offer high voltage capability in a surface mount package. Meeting MIL-STD-202 specification, the HVC series uses the latest thick film technology to meet voltage applications of up to 3kV.

Bridging the gap between low power, high resistance potentiometers and high power, lower resistance wirewound rheostats, Ohmite’s new PE Series thick film potentiometers have a metal shaft and ceramic housing to provide a smooth linear operation and low noise performance.
