USER GUIDE
Panel Mount Digital Tachometer
Model 461950
461950-EN v2.4 10/13 2
Introduction
Congratulations on your purchase of the Extech 461950 Panel Tachometer. This meter displays
continuous readings from 5 to 99,990 rpm. Single pulse activation eliminates the need for special
gears when setting up the meter in any given application. Models 461955 (proximity sensor) and
461957 (photoelectric sensor) are also covered in this manual. Careful use of these devices will
provide years of reliable service.

Mounting Instructions
Panel Meter Mounting
1. The 461950 dimensions are:
 Meter: 3.78 x 1.89 x 4.33” (92 x 42 x 90 mm)
 Bezel: 3.78 x 1.89 x 0.2” (96 x 48 x 5.1 mm)
2. Prepare a panel cutout with the following dimensions: 3.62 x 1.77" (92 x 45 mm).
3. The Tachometer will fit a standard 1/8 DIN cutout. Mounting hardware is provided which
attaches to the sides of the meter. The screws attached to the mounting bracket should be
tightened to the back of the panel (avoid over-tightening which can bow the meter housing).
Proximity Switch Model 461955 Mounting
Use the mounting holes to secure the proximity switch to the desired surface. The sensor is the side
of the switch that detects a moving metal object such as a gear tooth or a fan blade. The sensor
side of the switch has an X on it and is located on the opposite side of the switch from the wiring
cable. Refer to the top view diagram below. The Proximity switch must be mounted so that the
object being detected passes within 0.16" (4mm) of the sensor side of the switch. The pulse LED
will light when the sensor detects a metal object.
Photoelectric Sensor Model 461957 Mounting
Use the mounting holes to secure the photoelectric sensor to the desired surface. The photo beam
is generated and detected in the groove (as depicted by the dotted line in the diagram below). The
object under test must pass in the groove so that the light beam can be interrupted.
