Mounting Instructions

Panel Meter Mounting

1.

The 461950 dimensions are:

Meter: 3.61 x 1.66 x 3.54 " (92 x 42 x 90 mm)

Bezel: 3.78 x 1.89 x 2.36 " (96 x 48 x 60 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.
