Front Panels & Mounting Accessories for 19” Rack Systems

M-Pipes - Light guides with embedded SMD LEDs

Front Panels & Mounting Accessories for 19” Rack Systems

A range of MENTOR Front Panels and Accessories are available for 19” rack systems. Typical uses include blanking-off unused sections of rack systems; connecting double European pc boards; and front panel handles. Various sizes of MENTOR Panels are available, to suit most 19” rack systems.


M-Pipes are the first machine-insertable SMD LED light guide system for use in fully-automated production processes. This MENTOR system combines the design advantages of SMD LEDs with the flexibility of light guide technology. The light guides are suitable for use on all infra-red and vapour-phase soldering systems. Optimal light distribution and efficiency is provided, combined with very good ESD protection

Toggle Switches

The MENTOR Toggle Switches feature a design that offers automated production machinery a large surface area for good pick & place suction, resulting in high production throughput rates. The solder tags are designed to flex slightly, ensuring good soldered connections in the production process. Additional fixing pins enable exact alignment of the switch during production.

Push-Button Switches

The MENTOR Push-Button Switches are available in single-pole and two-pole versions. In 19“ rack system applications, they can be used as panel-mounted switches or as PCB-mounted reset switches. A fixing pin ensures correct alignment onto the front panel, it also provides physical support for the in-use actuating forces. Control knobs are available in various colours.

Push-Button Switches

The MENTOR Top-Button switches are available in a wide range of actuator heights, with different colours and actuator sizes.

DIP Switches

The MENTOR range of DIP Switches includes these options: 4; 6; 8; and 10 contacts.

Rotary Binary Switches

The MENTOR range of Rotary Binary Switches use high-quality materials combined with a tried and tested contact design, ensuring reliable switching characteristics across a wide temperature range. The switch settings are simply made with a slotted screwdriver. Other types of Binary Switch are available on request.

Miniature Key Switches

These MENTOR Key Switches are designed for front-panel use, providing security against unauthorised use. Two fixing pins and a collar ensure that the switch is securely mounted. The key is provided with a chain fixing.

SMD Bridges & Fuse Holders

SMD Bridge – a 0Ω Resistance Switch

MENTOR’s smallest switch is the SMD Bridge – a 0Ω Resistance Switch. It has a wide range of 0Ω Resistance applications including service bridge applications.

Fuse Holder for G-Fuse Links 5x20mm

The MENTOR fuse holder is designed for 5 x 20mm G-fuse links. The generous soldering surfaces ensure reliable soldered PCB connections. To provide additional support for PCB mounting, a fixing screw can be secured through the central hole in the fuse holder body.

Fuse Holder for TR5 Fuse Links

This MENTOR Fuse Holder is the only front-panel fuse holder for TR5 fuse links. It enables front-panel fuse-changing with no additional tools.

Test Jacks

Test Jacks Ø2 and Ø4mm

MENTOR’s SMD series of test sockets are designed for use in front panel applications. They have proven to be highly-reliable over many decades.

Plugs for Test- Switch Jacks Ø2mm and Ø4mm and Short-Circuit Plugs

The MENTOR pin-and-socket jack connectors meet DIN 41649 T1 structural shape definitions. The jack connectors are suitable for fine-strand conductor cables up to 0.5mm² with a maximum insulation diameter of 2.1mm. The connectors are silver-plated.

SMD LED Display Systems

Single LEDs – Horizontally-Mounted - Ø2mm, Ø3mm and Ø5mm

The MENTOR horizontally-radiating LEDs utilise a universal clip-on system. They are available in different LED colours, diameters and lengths, providing a gap between the printed circuit board and the front panel, ensuring increased ESD protection.

Matrix LED Arrays – Horizontally-Mounted - Ø3mm

Various Array configurations are available: 1Row/2 Columns; 2 Rows/2 Columns; 3 Rows/2 Columns. Many different colours are offered.

Single LEDs – Upright-Mounted - Ø3mm and Ø5mm

This MENTOR Series of Single LEDs radiate vertically as opposed to horizontally. Many different colours are available and the cylindrical versions offer enhanced ESD protection.

LED Buttons with Graphics

Illuminated Buttons with Surface Graphics

The MENTOR range of Buttons with Surface Graphics offers both surface and background illumination. Many low-profile applications are possible due to their low overall height. The system is highly-configurable, by combining various modules with different graphics. Many different types of graphics are possible, including Bargraph displays and custom symbols.

LED Tester

This easy-to-use MENTOR LED Tester can be used to test colour, illumination and light intensity.
